5" Exhaust System | Ram 5.9L Cummins | 2004.5-2007

The 5" DPF Delete Exhaust for the 2004.5-2007 Ram 5.9 Cummins is built by P1 Race Pipes from high quality, thick aluminized steel. It's a full-length exhaust system that removes the emissions parts from your exhaust and lets the 5.9 run unrestricted.

This one is designed for perfect fitment across all trims of the 5.9L Ram Cummins. As a full-length replacement, it swaps the entire exhaust path with a free-flowing pipe, taking the emissions parts that have been choking your diesel right out of the equation.

In the box you get the 5" thick aluminized steel full-length pipe from P1 Race Pipes, the hardware for installation, and a step-by-step installation guide. It's designed for perfect fitment with no welding required. It fits the 2004.5, 2005, 2006, and 2007 Ram 2500 and 3500, but not Cab & Chassis models without modification, and not the 6.7L Cummins.

With the restriction gone, exhaust gas temperatures drop under load, your turbo spools faster and builds boost more efficiently, and pulling the emissions system that's been suffocating the engine can improve fuel economy. You'll also hear that classic Cummins growl come through more clearly. A delete tune is recommended to clear any ECM codes, so call (888) 830-2588 and we'll confirm what your 5.9 needs before you order. Free shipping on every order, though Alaska, Hawaii, and some Canadian locations may carry additional freight charges.

For off-road/competition use only.
