VEHICLE FITMENT: 2021-2022 Ford F-150 5.0L V8 Regular Cab with 8 FT Bed 141.5" Wheelbase. 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 F-150 owner. Made from 3.0" 304 stainless steel construction and featuring CORSA's Best-in-Class No Drone RSC Technology, we've customized two unique exhaust sound levels for the F-150 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. "Xtreme" system is the loudest exhaust note we offer, noticeably more aggressive than the Sport system on both cold start and during acceleration while only inducing slightly more in-cabin volume. Dual Rear Exit style is up to 20dB louder than stock under heavy acceleration. All exhaust systems come with dual wall stainless steel exhaust tips and are 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.
