Frequently Asked Questions
What is the CORSA 14398?The CORSA 14398 is a 3.0-inch Sport muffler upgrade kit for the 2017-2020 Ford F-150 EcoBoost Raptor 3.5L Turbo. It replaces only the factory muffler section while retaining the factory mid-pipes, delivering CORSA's RSC drone-free performance sound at a lower cost than a full cat-back replacement.
What is the difference between the 14398 muffler kit and the 14397 cat-back?The 14397 replaces the entire exhaust system from the catalytic converter back, including mid-pipes, muffler, and tips. The 14398 replaces only the muffler section, retaining the factory mid-pipes and using factory tip connections. The 14398 is a lower-cost option for those satisfied with the factory tip routing.
Does the 14398 come with exhaust tips?The CORSA 14398 muffler kit is designed to pair with the factory exhaust tips or aftermarket tip kits. Tips are not included in the base 14398 kit. For a complete tip upgrade, CORSA offers separate Pro-Series tip kits.
Does installation require cutting or welding?No. The CORSA 14398 is designed as a direct bolt-on replacement for the factory Raptor mufflers using factory mounting points. No cutting or welding is required.

Is the CORSA 14398 drone-free?Yes. The 14398 uses CORSA's patented RSC technology, which cancels the low-frequency resonance that causes cabin drone during highway driving. The result is an aggressive note under throttle and a quiet, comfortable interior at cruise.
Is the 14398 legal in California?The 14398 does not modify catalytic converters or emissions equipment, making it street legal in all 50 US states. A California Prop 65 warning applies regarding chemical exposure.
