Description
Boost Your Sound. Growling aggressively and throatily when accelerating and subsiding to a pleasant rumble when cruising, the MBRP XP Series 3-inch Split Rear Exit Cat-Back Exhaust gives your 2014-2018 Silverado an exciting new exhaust note. The same features that make this system sound great – mandrel-bent tubing and a high-flow muffler – also make it an exciting performance exhaust. Under optimal conditions, the XP Series Cat-Back dishes out an extra +5% to +10% horsepower and torque by bleeding off backpressure and lowering exhaust gas temperature (EGT) by up to 200° F. To top it off, this cat-back is made from T-409 stainless to last your truck’s lifetime.
High Endurance Part. MBRP builds its XP Series Cat-Back Exhaust as a middle option between aluminized and T-304 – the T-409 won’t rust through, but may discolor with surface oxidation over the years. The tip is mirror-polished T-304 stainless steel, which will stay bright and clean looking. The tubing is 3″ diameter and mandrel-bent for smooth flow, with thick 16-gauge walls for extra sturdiness. This is a bolt-on system that comes with all hardware, clamps, and a limited lifetime warranty.
Application. This MBRP XP Series 3 in. Split Rear Exit Cat-Back Exhaust is designed to fit on all cab and box configurations available for the 2014-2018 5.3L Silverados. It will only work with a 1-piece drive shaft.
