Shopper Award

Really stand out from the crowd with this super aggressive AR-15 exhaust tip from Sinister Diesel. Designed to look like the quad-rail handguard on a real AR-15, a gun that's been used and respected by military and police officers for some time, you can show your interest in this popular firearm. Even better, it works on any diesel truck exhaust system that fits the 5-inch inlet, while providing a more intimidating 6-inch outlet.

Stainless steel construction and powder coating helps ensure durability, while the dual wall design sheds heat efficiently. Installation is a breeze, requiring only basic hand tools and a few minutes of your time.
