Atlas Aluminized Steel DPF-Back Exhaust System with Split Side Exit (49-04080-P) by aFe. Single To Dual Exhaust Conversion. Exhaust System Type: DPF-Back. Exhaust Tubing Material: Aluminized Steel. Main Tubing Diameter: 4". Exhaust System Sound: Moderate. The ATLAS Exhaust System channels the exhaust from the engine to the rear of the vehicle on a racing diesel engine truck. It has the least amount of exhaust flow restriction possible to enable the engine to make more horsepower and torque and operate with reduced exhaust gas temperatures.

An off-road exhaust system must safely carry harmful exhaust gases to the rear of the vehicle, away from the driver. But it must do so with the least amount of restriction, for maximum airflow and power, under the most demanding conditions. To achieve this, the right pipe size and every bend must be carefully calculated.

aFe tests its systems on the flow bench and the dynamometer to determine the right pipe size and muffler construction. Then they mandrel bend the pipes to ensure they maintain their shape and size throughout the entire length, to provide smooth, unrestricted airflow. Tubes that are not mandrel bent can lose up to 20% of their diameter in sharp bends. A free-flowing 12" wide muffler is included in systems that feature a muffler. Some systems include a straight muffler delete pipe if a more aggressive sound and maximum flow is desired.

But performance is only part of the equation. A quality exhaust system should be easy to install and made to last. The muffler and all pipes of the ATLAS exhaust system are constructed from aluminized steel. To ensure a tight seal, slotted and swedged ends are used whenever possible. When used with the supplied premium quality band clamps, the tightest, leak-free seal is the result. Every hanger is thoroughly welded on each side to ensure a strong attachment and the hangers also feature swaged bayonet ends to lock in place once installed. The factory mounting locations are used throughout and a 2-piece tailpipe facilitates adjustment.

Fixes flats and old tires like a charm
Style: 1 gal
This stuff is awesome. If you have tractor tires, ATV tires, bike, tires, hell, any tires that hold air. This stuff is awesome. Awesome. Awesome. It does not work for highway vehicles, i.e. Cars and truck trucks. But anything else it’s great. Dollies, air compressors, wheelbarrows, the stuff is awesome dude.

slime is and has always been amazing for bike tires and other small pneumatic tires
Style: 1 gal
this is a great value, I have been using slime in my tubes of my bikes and a small inflatable pneumatic tires for probably 30 years, and I can say slime has only improved, and it works fantastic, this is a very good way to save money, and it works great on goat heads and several other ways your tires can get punctured, I still always recommend carrying a small air compressor or pump, but for the price point you just cannot beat slime, every bike shop should always carry this.

TireJect Product Featured on Youtube Channel "sixtyfiveford" Works Fantastic!
Size: 8oz MTB Tire Sealant Kit, Size: 8oz MTB Tire Sealant Kit
I recently had an opportunity to work on an old Troy-Bilt Snow Blower with a Carlisle Stud Bias Tire - 4.80-8 4 that had a continual leak and would not hold pressure for more than a day. After investigation, I discovered that it "Champagne" sized bubbles coming from an area on the sidewall that I circled in yellow "China" marker. Because of the size of the tire, I decided to purchase the "TireJect Mountain Bike (MTB) Tire Sealant Kit because I didn't require a lot of material to seal the tire. The TireJect Mountain Bike (MTB) Tire Sealant Kit came with an single 8oz container and I used 4 of those 8oz's in this single tire. The TireJect material sealed up the area beautifully. After the sealant cured, I was able to pump up the tire to 15PSI and it has held it's pressure for more than a week now. You can see from the photos, that the sidewalls in that yellow circled area were actually cracked (probably due to the tire sitting flat for more than a year). I highly recommend this product over previous products I have used in the past (Slime).
