    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.

    will this work with the fuel management system without sounding like a putt, putt machine when only 4 cylinders are firing?

    buds

    • The MBRP 3 in. XP Series Dual Exhaust System is a standard exhaust and will not change any part of its configuration when your truck goes in to active fuel management/cylinder cut off mode.

      Review from MBRP 3 in. XP Series Dual Exhaust System - Rear Exit (14-18 5.3L Silverado 1500)

      Sounds and Looks Great

      Just had this system installed on my 14 Sierra All Terrain and it has a Great Sound and I also Added 5in tips which make it sound even better... NOW ONE NOTE, it is NOT a full 3in system!!!!!!! From the muffler back to the bumper the pipes are 21/2in, NOT 3in... Aside from that, it seems to be the best bang for the buck that I have found so I'll see how it works out... I'm a MAGNAFLOW user, but this shinny muffler seems to have that same mellow sound, unlike that other flow hollow beer can sounding muffler that seems to be so popular...Also with my KandN cold air intake, when you put your foot into it wow, makes you want to do it all the time...
