The 2020-Up Chevrolet/GMC 2500/ 3500 Duramax 6.6L is a workhorse of a truck that deserves some luxury, show your truck your appreciation by upgrading to MBRP's S6059304 Cat-Back Exhaust System. MBRP's Cat-Back exhaust systems have multiple benefits, here is why you should consider upgrading your OEM exhaust system for one of ours:

Durability: Constructed from T304 stainless steel, our systems are rust resistant and built to last. T304 Stainless steel is optimal for harsh or mild environments, because stainless steel has a lower carbon content and higher amount of chromium, it resists corrosion better.

Performance: A full exhaust system can significantly improve engine performance, with our exhaust systems all of the tubing is mandrel bent for maximum exhaust flow. Mandrel bending ensures no rippling in the bends. The end result is that it gives you more fresh air inside your engine's cylinders, allowing it to produce more power and improve vehicle performance and longevity. For the S6059304 we have also improved your exhausts cooling with our vented tailpipe.

Sound Quality: Our designs create a signature MBRP exhaust tone. For this Cat-Back we have developed a full body mellow exhaust tone, perfect for long drives.
