2011-15 DURAMAX 5IN DOWN PIPE BACK DUAL EXHAUST 5IN - WILL NOT FIT 2015 GMC DENALI HD TRUCKS

Ever hear someone say; "BIGGER IS BETTER"? We like to think so! The Flo-Pro R&D team has been cutting and bending the impossible to bring you the world's first 5 inch dual exhaust kits for the most popular trucks on the road today.



The 6.6L Duramax LML has its own clearance issues which make a true 5 inch dual system difficult, but not impossible.This down pipe back kit features a 4 inch front pipe which then converts into a 5 inch pipe that connects to our original 5 inch Y-Pipe. The tailpipes are designed to go up and over the rear axle and exiting evenly on either side.



The spare tire will have to removed for installation.



RACE ONLY / OFF ROAD USE ONLY / CAT & DPF DELETE.
