11-16 Duramax DPF Delete Pipe by P1 Race Parts Competition Exhaust Systems is an ideal solution to pair with a race tuner and delete your Cat and diesel particulate filter (DPF) off your diesel pickup truck. You must use a tuner when removing the DPF off of the vehicle.
This is a DPF Delete Pipe only, not a full Exhaust Kit.
This pipe is the V Band Flange. If you have the V Band Style please order the 11-16 pipe. You can see which type of flange you have by looking at the downpipe through the passenger wheel well.
