Description
Durable Power Boost. Voicing a deep, smooth growl that rises to a moderately aggressive, deep-throated note when you step on the gas, the MBRP XP Series 3-inch Split Rear Exit Cat-Back Exhaust vents exhaust strongly for maximum scavenging from the cylinders and headers. Sweeping away this fume buildup makes big positive dividends for your pickup’s performance, helping the engine run easier and with less strain – and a resulting +5-10% jump in torque and horses. You’ll likely also notice gains in throttle response and +1-2 bump in mpg. The twin 4.5″ polished stainless steel exhaust tips showing one on either side under the rear bumper gives your truck a dose of rugged good looks.
All-Stainless Construction. The MBRP XP Series Cat-Back uses stainless steel from front to back, including T-409 stainless for the 3″ tubing and the chambered, welded muffler, and premium grade T-304 stainless steel for the tips so they stay bright and untarnished. A limited lifetime warranty applies to this rust-proof component.
Easy Installation. 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.
Application. The MBRP XP Series 3-inch Split Rear Exit Cat-Back Exhaust is designed to fit with all of the cab and box configurations available for the 2014-2018 GMC Sierra’s equipped with the 5.3L engine. The kit will only work with a 1-piece drive shaft.
