The Flo~Pro 5" DPF Back Single Exhaust is a direct-fit exhaust upgrade built specifically for the 2007.5-2010 Chevy/GMC 2500HD/3500HD 6.6L Duramax. Fabricated in Alberta, Canada from U.S.-sourced heavy-gauge steel tubing, it replaces restrictive factory piping with a full 5" flow path to help lower EGTs, sharpen throttle response and give your diesel a deep, clean, aggressive tone.
A DPF-back system bolts on behind the factory diesel particulate filter and replaces the rear section of the exhaust through to the tailpipe, upgrading flow and sound while keeping the factory aftertreatment in place.
