Adding a new cat-back system to your F150 is the perfect way to achieve a better exhaust note, while allowing the opportunity to compliment your other mods such as a cold air intake, tuner or other bolt-ons. This 4” cat-back S5259409 is made of T409 stainless steel, is 4” in diameter and exits through a single 5” mirror polished tip just behind the passenger side rear wheel.

When releasing a new exhaust system, MBRP puts countless hours on the street, dyno and track to ensure that you are getting the best quality exhaust out there. They design their exhaust systems not only to last through the test of time, but to produce the maximum amount of power while balancing the perfect exhaust note throughout the entire RPM range. Since you know this system is made of T409 Stainless Steel, you can sleep tight knowing that you are getting the highest quality possible. Another factor that MBRP takes into account is building fully sealed exhaust systems. Since seams are a major point of rust on any budget exhaust system, it’s important to have as little seams as possible to ensure long lasting reliability.

The stock F150 cat-back sees 477 CFM but MBRP's cat-back flows 877 CFM. With an exhaust flow increase of over 70 percent, you can expect great gains in both horsepower and torque. Installation of the MBRP S5259409 4" Side Exit Cat-Back Exhaust System is relatively easy, needing only a few hand tools to complete.

The EcoBoost engines available on the 2015-2020 F150 make minimal noise from the factory. If you want to hear the turbo(s) better, then picking up this MBRP Cat-Back Exhaust System is the perfect choice. These systems pump up the decibels without making your ears ring. The exhaust notes are subtle and manageable when cruising down the highway but will roar when you mash on the throttle. Given all the pros of this system from MBRP, how do you say no to throwing this exhaust on your F150?!

Please Note: Extension pipe will need to be cut, or not be needed at all for some cab and bed configurations. Shortening of the front pipe will be required to fit smaller wheel wheelbase configurations. Please refer to installation instructions.
