MBRP’s name is one of the big ones in the world of off-roading – a well-merited fame that comes from the consistent quality of its 2007-2018 exhaust components for the Sierra. MBRP started out with a limited snowmobile market but soon branched out to all kinds of performance exhaust thanks to their skill at making highly functional parts. The company’s 2007-2013 cat-back exhaust systems are organized more neatly than those of most competing companies. All their cat-backs use an identical design – a high-flow muffler, mandrel-bent tubing, and so forth – that generates +5% to +10% gains in horsepower and torque, along with 200° F cooling of the exhaust gases. Where their various 2014-2018 cat-back exhausts differ, however, is in material – you can get lower-cost, less-durable aluminized steel cat-backs, mid-cost and mid-durability T-409 stainless variants, or more expensive but rust-proof T-304 stainless systems. American Trucks stocks all “levels” for your convenience.
