    Affordable Performance Boost. Aluminized steel construction makes the MBRP Installer Series 3-inch Split Side Exit Cat-Back Exhaust a cost-effective option for your 2014-2018 GMC Sierra, while retaining all the premium design features of MBRP's aftermarket exhaust systems. Gains from the system's improved flow amount to +5-10% horsepower, a similar percentage boost to torque, better throttle response, +1-2 mpg, less chance of a breakdown, and improved lubricant longevity. Apart from all these improvements, the Installer Series also makes your truck sound more adventurous – creating a vigorous, deep rumble that is still pleasing and drone-free, and not harsh or grating.

    Aluminized Build. The MBRP Installer Series Cat-Back features thick 16-gauge aluminized steel for its 3" piping, and T-304 stainless steel tips to ensure brilliant, rust-free looks. The aluminized steel is further corrosion proofed via aluminum silica applications to the seams and welds. Your investment is protected by a 3 year limited manufacturer's warranty.

    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 Installer Series 3-inch Split Side Exit Cat-Back Exhaust is designed to fit with all of the cab and box configurations available for the 2014-2018 GMC Sierra's with the 4.3L engine.
