The 0FG is a 3 T304L stainless steel Cat Back configuration featuring AWEs patented drone-canceling 180 Technology. Together, combined with precision fitment, class-leading rigidity, and tailored tip options for all bumper variations, you're looking at the Best Sounding Exhaust on the Planet for the 4th Gen RAM. American-sourced T304L stainless steel with a wall thickness of .065 runs smoothly from front to back, connecting right after the factory emissions equipment. After exiting the 180 Technology resonator, the exhaust splits into dual 3 piping up to the tips. Perfect tone, compliments of AWE 180 Technology. Keeping the aggression at the rear of the RAM, and out of the cabin, is AWEs patented drone-canceling solution, 180 Technology. This system is the dual rear-exit, 5 double-walled straight-cut tip'd system, in Diamond Black. And check this out: the AWE BashGuard comes standard with this system, and is designed to provide drivers who frequently crawl rough terrain peace of mind with a simple conversion that shortens the exhaust, so it ends up and over the rear axle. Just unbolt the rear section of the exhaust, and pop the included Bash Guard in its place, and you've got protection from rocks and the occasional comet. Tips when you want em, protection when you don't. Easy. The AWE 0FG Dual Rear Exit Cat Back Exhaust is the last exhaust you'll ever need for your RAM. Guaranteed for life.
