The MBRP S6032304 is a 4-inch Armor Pro filter-back exhaust for 2011-2019 Chevrolet Silverado and GMC Sierra 2500HD/3500HD crew cab and extended cab pickups with the 6.6L Duramax. It is built from T304 stainless steel, finishes with a 5-inch OD tip and carries a lifetime warranty. You buy it for a bolt-on stainless system that holds its looks in tough conditions.

Fitment

Fits 2011-2019 Chevrolet Silverado 2500HD/3500HD and GMC Sierra 2500HD/3500HD pickups with the 6.6L Duramax: the LML (2011-2016) and the L5P (2017-2019). MBRP's application note: All Crew & Extended Cabs applies to GM 2500HD/3500HD Pickups. This system is not designed for use on Cab & Chassis models.

It is not listed for regular cab trucks. If your truck is a Double Cab, call us to confirm before you order. Exhaust routing changed with the 2020 frame, so 2017-2019 DPF-back systems like this one do not fit 2020-2023 trucks. Verify fitment by VIN before you buy.

Why this part

A filter-back system replaces the exhaust behind the factory diesel particulate filter. On 2017-2019 L5P trucks, exhaust upgrades are DPF-back: the DOC, SCR catalyst and DPF stay in place. This system follows that layout. You get 4-inch T304 stainless pipe from the filter back and a 5-inch OD tip with MBRP's stamped logo.

Armor Pro, formerly called Pro Series, is MBRP's T304 stainless tier. MBRP calls it the product of choice for owners of lifted trucks, show trucks and trucks that operate in severe environments. T304 stainless is easy to clean and maintain, and it keeps looking its best. MBRP points buyers toward its stainless tiers where road salt or brine is used and toward aluminized Armor Lite for dry climates. It is one of the DPF-back exhaust systems we carry for the Duramax.

Frequently asked questions

Does this system keep the DPF?

Yes. It is a filter-back system, so it starts behind the factory diesel particulate filter. On 2017-2019 L5P trucks, the DOC, SCR catalyst and DPF all stay in place.

Will it fit my 2020 or newer Duramax?

No. Exhaust routing changed with the 2020 frame, and 2017-2019 DPF-back systems do not fit 2020-2023 trucks. This system is listed for 2011-2019 only.

Will it fit a cab and chassis truck?

No. MBRP says this system is not designed for use on Cab & Chassis models. It is listed for crew cab and extended cab 2500HD/3500HD pickups.
