CORSA Performance's 2021+ F150 Exhaust Offering Has Arrived! Featuring a wide range of exhaust systems and exit options (Front of Tire, Side Exit and Dual Rear), CORSA's catback exhaust assortment has an exhaust system for every F150 owner. Made from 3.0 in. 304 stainless steel construction and featuring CORSA's Best-in-Class No Drone RSC(R)Technology, we've customized two unique exhaust sound levels for the F150 customer. CORSA's in.Sport in. sound level offers an aggressive cold start, moderately aggressive exhaust note under acceleration while maintaining stock levels of in-cabin volume. CORSA's Xtreme?¡?¡(TM) 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. 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 chasing the in.Science of Sound in.?? and are proudly made in the USA and backed by a Limited Lifetime Warranty.
