If its time to give your Duramax some added sound, performance, and a clean exhaust outlet (instead of the factory trumpet), then get ready to mount up an MBRP Dual Outlet 4" DPF Back Exhaust Kit.  This system comes complete with all necessary hangers and a pair of polished exhaust tips for a simple and complete installation.


Aluminized Features:
Built from heavy duty aluminized steel, the Installer Series performance exhaust systems offer a value price without compromising on the quality built into every component. While the seams are a major point of rust through with some budget systems, this fully sealed tubing adds years to your system. Constructed to the same specifications as MBRP's top of the line Pro Series, they back this line with an industry leading 3 Year Warranty.

T409 Stainless Steel Features:
MBRP's XP Series is the performance exhaust of choice for the enthusiast who needs a system that can take anything that the road throws at it. This system's rugged sixteen gauge T409 construction can be counted on to withstand everything from salt to rocks, tar to grime. MBRP even backs it with a Lifetime Warranty.

T304 Stainless Steel Features:
MBRP's Pro Series is the best performance exhaust system that money can buy. It is a series designed and built for the serious enthusiast who will settle for nothing less. Constructed from T304 stainless steel, it delivers you optimal durability that keeps on looking its best. Easy to clean and maintain, this is the product of choice for owners of lifted vehicles, show trucks, or who operate in severe environments.
