Pacemaker Full Twin 2.5" Performance Exhaust System with 1 3/4" 4-into-1 Tuned Headers & Hi-Flow Cats for Holden Commodore VE & VF Sedan (6.0L & 6.2L V8) - PP5381-11
Unleash significant torque fields, optimize mid-to-high RPM cylinder scavenging, and deliver an aggressive, deep Australian V8 muscle note from your small-block engine with the Pacemaker Sport Systems complete twin 2.5-inch performance exhaust solution featuring 1 3/4" 4-into-1 tuned primary extractors. Meticulously engineered to balance optimal exhaust gas velocity tracking with excellent total volumetric flow, this 1 3/4" primary setup serves as the ideal high-efficiency configuration for standard to moderately modified or daily-driven street performance builds. Specifically configured for the high-performance Holden Gen IV 6.0L and 6.2L V8 engine architectures, this premium full system is precision-molded to trace the sedan floor pan lines, clear standard wheelbase chassis channels, and map perfectly around the multi-link independent rear suspension geometry of the VE and VF series architecture. By upgrading your stock layout to high-flow competition 4-into-1 headers paired with smooth, mandrel-bent twin 2.5" plumbing and 3" high-flow metallic catalytic converters, it maximizes gas velocity tracking to completely eliminate power-robbing backpressure under heavy acceleration. As Australia’s premium exhaust innovator, Pacemaker integrates elite structural engineering with patented V-Tex technology and signature double-skinned mufflers, producing an authoritative performance roar on throttle while actively engineering out harsh interior cabin boom or sedan body resonance to preserve a completely clean, drone-free highway cruising experience.
Note: Fits Holden Commodore VE and VF Sedan variants built from July 2006 to October 2017 equipped with the Gen IV 6.0L or 6.2L V8 engine layout; does not fit Utility (Ute), Sportwagon, or long-wheelbase Statesman/Caprice platforms due to structural floor pan, intermediate pipe lengths, and rear hanger assembly differences.
Features:
Precision-manufactured in Australia to deliver a high-velocity flow upgrade, maximum structural longevity under intense heat, and a refined performance acoustic profile for the iconic Holden V8 sedan platform.
- Complete Performance Kit: Comprehensive track-and-street performance solution incorporating high-flow 1 3/4" 4-into-1 headers, 3" metallic high-flow catalytic converters, and a full matching twin 2.5-inch performance intermediate-to-rear exhaust layout.

- Premium Materials: Constructed completely from durable, heavy-gauge Exhaust Grade 409 Stainless Steel to ensure superior structural longevity and resistance to thermal fatigue under extreme loads.
- Mandrel Bent Tubing: Rigid twin 2.5" (63.5mm) pipe structure guarantees a smooth, uniform internal diameter through all bends to eliminate gas turbulence and prevent restriction.
- V-Tex Technology: Advanced internal patented anti-drone configuration filters out harsh, low-frequency cabin resonance typical of sports layouts without creating any power-robbing flow restrictions.
- Signature Mufflers: Heavy-duty double-skinned 409 Stainless Steel mufflers offer premium outer case reinforcement, preventing case distortion and internal packing blowout under heavy thermal load constraints.
- Direct Bolt-On Layout: Engineered as a comprehensive, vehicle-specific full bolt-up kit that mounts directly onto existing factory rubber hanger positions—no custom fabrication required.

Awesome robo-vac/mop with rotating mop head/no pads.
Size: E25 Black
I owned a Narwal Freo for 1 year and it died right after the warranty period was up. Tried replacing the battery but that did not fix the issue so I had to purchase another one. I noticed this eufy had high reviews and the 1 star reviews seemed to be just isolated issues so I purchased this one. Right away I noticed that the instructions/setup was much more simple. Second this one has a big wide mop roller on the front and after mopping I didn't see the mop streaks in circular patterns on the floor like I did with the Narwal as it had two rotating mop heads on the front so the single mop roller seems to be a better solution. Setup consisted of removing protective wrappers off of the tanks and base station, filling up the clean water tank, installing the detergent bottle and plugging it in. Next I downloaded the app and connecting the vac/mop to my network. This was SIMPLE to say the least. From there I could have just clicked clean on the app and it would clean the entire house. However, mapping gives you more flexibility when planning your cleaning ritual. You can define no go zones and clean rooms in any order you choose. I have a shedding dog so I have a separate robovac to clean up the dog hair prior to vac/mopping. This is a MUST with any robovac/mop combo as the dog hair on the floor will mix with the water and detergent and eventually prevent the mop from doing a good job. It will make a mess in the bottom tray of the base station too. I learned this through experience and reading all the one star reviews from customers. Robovac only cleaners last a LONG time. I had one that is still working great for over 3 years. All I had to do was replace the battery so it doesn't have to pause the job to recharge. So the mapping only took 4 minutes and it was pretty accurate. After the mapping I defined the room boundaries and renamed the rooms. Next I sent it off to clean and it did a FABULOUS JOB! No streaks and the floors are clean. The noise level is really low and more quiet than the Narwal. The other thing I noticed is it didn't use up much water to rinse the mop while cleaning. The Narwal used a lot of water and I was always dumping dirty water and adding fresh. I will always have a robomop and robovac as they save me so much time by not having to do this job twice a week. Connectivity to my network is excellent as it's in a location far from the router. This vac/mop is a good value for the money if IT LASTS BEYOND 1 YEAR. I will update this review as necessary and if it fails right after the warranty period I will report and downgrade this review to 1 star. These companies need to learn the importance of reliability and correct these issues. When I first reviewed the NARWAL it had almost a perfect 5 star review from all customers. After the year was up and it failed that star rating went down to 3+ stars. Most reviews reported their robovac/mop just died like mine did after the warranty period. I downgraded my review and reported the issue. I'm hoping this one will last because at the moment I am VERY satisfied with it like most customers. This model has been on the market much longer at the time of purchase so I would suspect if there were any reliability flaws they would have been addressed and corrected by now. We shall see. At this time I highly recommend!!

Excellent Robot Vacuum, Especially for the Price
Size: 11S, Size: 11S
I have been an iRobot Roomba buyer since 2007. My last Roomba bit the dust this month, and I did a ton of research before buying a replacement. I went with the Eufy for a few reasons: price point, cleaning power, quietness, and sleek design.
Price: Very reasonable. Almost reasonable enough that I'd consider getting another one for my second floor. For now I'll just carry it upstairs.
Cleaning power: This thing sucks... It's suction is much stronger than my Roombas have had. It picks up so much dust and pet hair. We do a full vacuum every other week with my Dyson, so I think of the robot vacuum as a supplemental vacuum. I was shocked at how much was in the dustbin after it's inaugural cleaning! The picture attached to this is from that cleaning. It also gets a ton of dust in the little dust filter. In one of the video reviews I watched, the reviewer said it didn't pick up anything in that dust filter... So maybe my carpet is particularly dusty, because it has a thick layer after each cleaning.
Quietness: I work from my home office, and this thing is quiet enough that I don't even turn it off during conference calls. This might be the thing I am most impressed with. My last Roomba was LOUD-- you couldn't even have a conversation with someone in the same room, let alone someone on speakerphone.
Sleek design: I love/hate this. It definitely looks modern and cool, and more like an art piece than an appliance, but it shows all my finger prints, and now I keep a glasses cleaning cloth nearby so I can rub it down. I suppose if I only use the remote and never pick it up, this won't be an issue.
A few considerations: I was hoping to find a robot vacuum that wouldn't eat my carpets' tassels, but I don't think that vacuum exists. I have only used the Eufy 4 times so far, and it doesn't always get its brushes wrapped around the long tassels, but it does sometimes. It seems to realize it sooner than my Roomba did at least. The Roomba would sometimes rip gobs of them off in a single cleaning. I try to tuck them under the edge of the rug and that doesn't seem to bother Eufy. It has pulled off probably 2 tassels so far.
The cleaning pattern seems pretty random. I saw some other vacuums that chart out complex maps of your home, and Eufy doesn't seem to do that. But, it doesn't seem to matter, because it still hits every spot in the rooms.
I'm a little concerned about durability. My Roombas ran for many, many years with easily replaceable parts. We'll have to see if Eufy has the same longevity.
All in all- I'm very happy with my purchase and definitely recommend it!

Robot Vacuum With Decent Cleaning but Too Much Maintenance
Size: E28
This robot vacuum was fairly simple to set up, and the battery life is actually pretty good. When it comes to cleaning, it does a solid job picking up dirt and debris, and overall the suction works well for everyday vacuuming.
However, the navigation and sensors really missed the mark for me. It struggled to recognize certain items around my house. For example, the mat under my cat’s food bowl kept getting caught because the vacuum didn’t detect it properly. It also had trouble recognizing furniture like my ottomans and would repeatedly run into them.
Another issue was how it handled different floor types. It’s supposed to be able to recognize surfaces like carpet versus hard flooring, but that didn’t always work correctly. At one point it even tried cleaning my carpet when it shouldn’t have. It also struggled with room detection and didn’t consistently recognize different areas of my home, even when placed directly in them.
I bought this hoping for more of a “set it and forget it” type of appliance since I work a lot and wanted something that would keep my floors clean without much attention. Unfortunately, that wasn’t my experience. I often had to redo the mapping or move the vacuum around so it could recognize spaces and objects properly.
There were a few positives though. The app is very helpful and easy to use, and the vacuum communicates clearly through notifications. It lets you know when things like the water level or cleaning bin need attention, which I appreciated. Maintenance like emptying it isn’t required very often either.
It’s also a little noisy. Not extremely loud, but it talks frequently and you definitely know when it’s running. Since I work third shift and sleep during the day, that was a bit frustrating.
Another issue was that it struggled to cross small entry thresholds between rooms. Even a small lip between rooms would sometimes stop it from moving into another space.
In the end, I decided to return it. While it does vacuum fairly well, the navigation issues and constant adjustments made it more of a hassle than a convenience. For the price, I expected something more hands-off, and unfortunately it required more attention than it was worth for me.

Great and Easy to Use!
Size: 11S
Background: I have a shedding dog, so I bought this in hopes that by running it every-day, it would pick up on some of the dog hair on the floor.
What I like:
-VERY easy to use.
-easy to follow instructions
-has a sticker on the bottom so if it ever stops and beeps, you can flip it over and it says exactly what the beeps mean (one beep means one thing, two beeps means another--which is SUPER helpful!).
-color on top clearly shows what mode it is in (blue-ready to go, orange-needs to charge, red-problem to fix-such as emptying the tray).
-very quiet. I can work on stuff with it in the room and it does not bother me at all (my dog also does not mind it).
-works great on white carpet and easily transitions from my living room to dining room (which has a slight bump).
-when its low on battery, it does not die where it is at, it just turns off the vacuum then finds the home doc and charges itself.
-just works really well. I run it everyday and I am impressed by how much stuff it gets (especially when it goes under things such as the couch).
-if it gets caught on a cord, it usually takes 5-10 seconds but then it stops the suctioning and moves away (releasing the cord or other item). However if you have a small cord you should put it up (and you should regardless, I just noticed it doing this a few times and thought it was neat, but I do try to pick up all cords).
What could be improved:
-nothing really in particular to this.
-It does not work well on anything black, but this is true for all robot vacuums. It sometimes gets stuck when it goes on the black carpet we have with the black chairs (I suspect because it can not detect them), but this has not happened often. My dog has a black mat for her food and water and it always bumps into it and spills the water, but again, this would occur with any robot vacuum.
-Also, make sure the doc is against a wall because otherwise it will move and never charge (self explanatory, but I did not do the first time and it kept trying to doc and was just pushing the doc around the floor).
-Finally, you do have to dump out the vacuum particles almost every time you run it (if you do a full circle/battery cycle). It is really easy to dump and beeps when it needs to be emptied. Again, nothing really negative, just something to note.
Overall, I really like this! It does a nice job cleaning up the dog hair and other things that get on my floor and saves me a lot of time not vacuuming daily. If you have a dog, I would watch them with this first before you use it. My dog was initially scared of it but sniffed it's "butt" and now they are cool and she does not mind it at all. Pleased with this product and would recommend! :)
**UPDATE**
On another note, Eufy has amazing customer service! I received an email from them addressing each of my "what could be improved" components with more information on the product. Very impressed.

ROB is amazing.
Size: E25 Black
I have to first explain that I have named my E25, his name is now ROB and will be referred to as ROB going forward.
ROB has been an amazing addition to our family and yes I said Family. ROB was easy to set up, all instructions were clear and easy to follow.
The first day, I followed ROB everywhere afraid he would get stuck on a rug, or would have difficulty making it over the transitions of our flooring. But ROB had no problems what so ever. And honestly, I found myself amazed at the quality and endurance of ROB. He was jumping over transitions, flipping from mop to vacuum at the proper times and would suck up a dog hair bunny from 3 feet away! As a home with 2 big dogs (over 100 pounds each) that looses enough fur to make a new sweater everyday, ROB has done an amazing job! It’s been a week with ROB and I have found that he takes no prisoners, there was an area that I didn’t want him going into because I had boxes laid out, I was lazy and just made a make shift barrier so he wouldn’t proceed through the area, but ROB was persistent and was able to move the barrier so he could do his job. So, if you want a robot that will jump a shoe wall, ROB is your man! ROB navigates around a dog toys, around dog bowls, and can even get rid of the doggy dribbles when they drink.
I have ROB set up to vacuum during the day and at night, he vacuums and mops. My 2 dog sons and my family are all happy with ROB as he is quiet and doesn’t scare them. Most days they just watch ROB do his magic on our floors. ROB also cleans himself, he will run home to clean his butt after mopping and will empty his own debris from his vacuuming. I really don’t know how I survived without ROB this long!! I waited 6 months before I finally purchased ROB after seeing his brother BOB in action at my Cousins house. So don’t be like me and wait, just make the purchase. You won’t regret it.
