Description
High Performing Cat-Back. Jaunty styling in the form of a single, massive 4.5″ exhaust tip with a mirror finish gleaming behind your 2009-2013 5.3L Sierra’s rear wheel is matched by the mellow but sporty exhaust note of the MBRP XP Series 3-inch Single Side Exit Cat-Back Exhaust. If you’ve been craving a more virile sound for your pickup, the XP Series supplies it, deepening and enriching the sound of the exhaust flow. The unrestricted flow of exhaust fumes out the tailpipes also frees up the system’s potential, letting more air/fuel mix reach combustion faster without having to fight backpressure – translating to +5-10% HP and torque gains, plus +1-2 mpg fuel economy.
Quality Upgrade. The T-409 stainless steel of the MBRP XP Series Cat-Back’s construction, from the 3″ mandrel bent 16-gauge pipes, to the chambered and welded muffler, gives this system long-term endurance free from rust-out. The limited lifetime warranty proves the T-409’s effectiveness at making a rugged, lasting system. The tip is even higher grade T-304 stainless that won’t discolor.
Ease of Install. The installation process of MBRP Cat-Back Exhaust is easy and the exhaust system can be installed with common hand tools. The bolt-on, no weld design provides you with a hassle-free installation process that can be completed in approximately 1-2 hours. Depending on your cab and box size, some cutting to the piping may be required.
