THE FULL STORY:

The Honda CRF450R is a serious threat on the track. With their mean 449 cc, single cylinder 4-stroke engine, incredible handling, and light-weight, durable design, taking down the competition never felt so good! Honda has certainly designed a spectacular motorcycle with their CRF450R, so it's easy to see why so many riders call this bad boy home on the race track.  

When you want to take your CRF450 up a notch, install a Barkers Full Single Exhaust System! A Barkers Full Single Exhaust System will increase overall performance by increasing horsepower and torque across the entire power curve. Eliminate that sudden fall-off that occurs near redline with the stock exhaust system when you install a Barkers Full Single Exhaust System. Not only does the Barker Full Single Exhaust System weigh less than the stock exhaust, it will deliver that deep, throaty sound you've been searching for! 

 

Here is our Dyno information, provided by Alex at LaBaron's Power Sports 

These are the results for the 06 crf450r. These charts and jetting specs should be applicable to all CRF450r bikes from model year 2003-2008. Final results are as follows Green: stock pipe and jetting, Blue: Barkers exhaust with no QC and stock jetting, Red: barkers exhaust and dyno tuned jetting setup. Jetting recommendations are : 165 main jet (168 stock), 45 pilot jet (42 stock), stock needle in 5th position from top (4th stock), 100 pilot air bleed (stock), #55 leak jet (stock).


Did you look at the dyno? Did you see that unusual blip? That's from the Rekluse aftermarket clutch!

All of Barkers Exhaust Systems are hand-crafted right here in the USA from premium materials. While most other after-market exhausts are mass produced from automated assembly lines, Barker's Exhaust systems are hand-welded one-by-one by skilled craftsmen. The head pipe portion of the Full Single Exhaust System is 304 stainless steel that is Tig-welded with seam-reduced interior surfaces for smooth flow. The can is comprised of 6061-grade aircraft aluminum and comes standard in a brushed aluminum finish. For a more customized look, you may also choose to have your can powder-coated in a black or red finish. Further enhance the look of your new system by selecting which color Barker's tag you would like. Barker's tag color options include: black, blue, red or yellow. To harness your new system to your machine, a strap kit is included with your purchase.

 

At Barkers, we have an extreme amount of dedication and respect for the off-road lifestyle. And we understand that owning and maintaining a performance vehicle is no joke. That is why you can expect only the best in Barker's craftsmanship and design. All Barker’s exhaust systems carry a limited one-year warranty against defects in workmanship and/or materials. See Barkers Terms & Conditions.

ADD-ONS:

Other options available for the Full Single Exhaust System for the Honda CRF450 machines are the Barkers Quiet Core Insert and Spark Arrestor. The Barkers Spark Arrestor will help to keep our trails safe by eliminating any flammable emissions from escaping the exhaust. The Barkers Quiet Core Insert is ideal when riding in those sound sensitive areas and will reduce sound by up 5 dB. Heck, with only a loss of .5 to 1.5 horsepower you might want to ride with them in all of the time.  

For serious riding, we highly recommend purchasing a fuel controller for your new system. A fuel controller will drastically improve the way your new exhaust system and Honda CRF450 performs. As your new system will require the added fuel flow, a fuel controller is essential for your CRF450 to perform at it’s best. For optimal results, your dealer or a skilled technician should program the fuel controller prior to installation. If you are interested in learning more about why you should purchase a fuel controller, please feel free to call us! We promise you will talk to a real person who knows all about it!

Pawesome variety box!
Size: Large, Color: 9 Packs, Size: Large, Color: 9 Packs
I’m a big fan of this box of tug toys. My dog loves to chew and play tug-of-war, and these have been a great fit for him. The quality is solid, and one box typically lasts us around 6 months. He’s now 3.5 years old, so he doesn’t chew as aggressively as he used to, which helps them last even longer. You get a great variety in this box. It’s honestly like Christmas for him every time I bring out a new toy. I usually grab a couple and let him pick. The different shapes and sizes keep things interesting, and he enjoys all of them. The toys are lightweight but very durable, even for an aggressive chewer like mine. The material is made of thinner rope strands, but they’re tightly woven, which makes them ideal for both tugging and chewing. I also think the texture helps with his teeth and keeps them a bit cleaner. I do keep an eye on them once they start to unravel, since I don’t want him swallowing loose strings. That said, it takes a while for him to break them down, so I’m comfortable leaving them with him when I’m not home. I’ve bought several of these boxes over the years. For the price, it’s a great value—about the same cost as a single tug toy at most pet stores. My dog is about 55 lbs, and these are a great size for him. Even the smaller ones get a lot of use. His favorites are the looped ones and the ones with balls—he gets excited every time I pull one out. I’ve tried other tug toy variety packs, and they don’t compare to this one. If you’re looking for a reliable variety pack for your dog, I’d recommend this one with confidence.

Revenge is sweet
Size: Large, Color: 14 Packs
The package arrived promptly. The puppy was ecstatic. She leaped into the pile of toys and went crazy. She tore through one after another. In mere minutes she devoured everything in sight. They never stood a chance. Within an hour or two she had consumed the entire pile of toys. Not to worry they had their revenge. She puked multi color string for days. Overall the toys were fun just not durable.

Very very durable
Size: Large, Color: 9 Packs
So after spending quite a bit of money on toys for a 1-year-old long-haired dachshund because she's a very aggressive chewer I took a chance and bought this rope set and it's been 2 months she still has all her ropes everything I must say this is a very durable set well worth the money well worth the play time she loves tug of war these ropes are great for tug of war she has not chewed through any of them she has tried to take them apart which she had succeeded on one but I put a few knots in it and other than that I would recommend this rope set to anyone that's got a dog that likes the fat especially play tug of war or is a very very aggressive sure
