2011-2015 Duramax LML 5" Downpipe Back Exhaust No Muffler (531006)

Constructed out of 16 gauge aluminized steel or T409 Stainless, this exhaust system is designed to simplify installation with included clamps, preweld contour bends and improved flanges. Enjoy a noticeable boost in performance, lowered EGTs and amplified air flow with this Mel's system. For powerhouse performance, Mel's delivers - horsepower you can hear!

IMPORTANT NOTE: The turbo direct pipe on some of the 2015 models has a 3-bolt flange instead of a V-band clamp. These kits will only fit models equipped with v-band clamp and will not work for trucks equiped with the 3-bolt flange off the turbo direct pipe!
