PRODUCT DESCRIPTION

CORSA's catback exhaust assortment for the F-150 offers a wide range of exhaust systems and exit options (Front of Tire, Side Exit, and Dual Rear) for every F150 owner. Made from 3.0" 304 stainless steel construction and featuring CORSA's Best-in-Class No Drone RSC® Technology, we've customized unique exhaust sound levels for the F150 customer:

"Sport" sound level offers an aggressive cold start, moderately aggressive exhaust note under acceleration while maintaining stock levels of in-cabin volume.
> All exit styles are up to 14dB louder than stock under heavy acceleration.

All exhaust systems come with dual wall stainless steel exhaust tips and come available in both polished and black PVD coating. CORSA Performance exhaust systems are made possible through a 20+ year commitment to perfecting the "Science of Sound©" and are proudly made in the USA and backed by a Limited Lifetime Warranty.
