4″ and 5″ Turboback-Back DPF & CAT delete exhaust system.  Exhaust shown is a 2004.5-2007 Ram.
Vehicle fitment – 2004.5-2005, 2006, & 2007 Dodge Ram 2500/3500 Cummins 5.9L Diesel. Regular cab short and long bed, Crew cab short and long bed & mega cab. This will not fit the Cab & Chassis commercial style truck.  2004 is different from 2004.5 please make sure you order the correct year. They have a different turbo elbow.
Exhaust Material – Available in aluminized steel or T-409 stainless steel. Aluminized steel is our most popular but will eventually accumulate surface rust. T-409 stainless steel. Unlike T-304 Stainless its still magnetic. So if your testing to see if you actually got stainless; beware that a magnet will still stick to it. We suggest the stainless upgrade if you regularly operate your truck on salted winter roads. Use drop down menu to make desired selection.
Installation – Install takes approx. 1hr with basic hand tools done on the ground of your driveway or garage. Quicker if you have automotive style lift. Cutting may be be required to fit shorter wheelbase bed/cab configurations. Clamps, hangers and hardware are included. You may have to re-use some factory hardware.
Fuel Mileage – Expect to see a significant increase in fuel mileage. If your DPF is plugged up your probably averaging about 13-14 mpg. More or less depending on the severity of the restriction. After deleting the DPF/CAT expect to get a combined mileage of 18-19 mpg. Larger tires and poor driving habits will skew mileage downward.
Tuner Required – Removal of the DPF, CAT, SCR, and/or DOC involves removing and eliminating emission related sensors. A DPF delete capable tuner is required to prevent any check engine light or diagnostic trouble codes from setting. If you don’t already have a DPF delete capable tuner we recommend the Ez lynk here.
If you need multiple exhaust add to cart separatelyÂ

Good price for the stainless steel very easy to install and install went pretty smoothly. Nice to have extra hardware and tip with it. Makes the truck sound so much better give it a 10/10 for quality. Only problem I had is you gotta some how mount the transmission dip stick back away from the down pipe from the turbo else you get a little rattle noise.
