Give your 5.0L-powered F-150 a louder, more aggressive exhaust note and a balanced performance-truck appearance with the CORSA Xtreme 3.0-Inch Cat-Back Dual Rear Exit Exhaust System. Designed specifically for 2021-2026 Ford F-150 5.0L V8 Regular Cab trucks with the 8-foot bed and 141.5-inch wheelbase, this system combines CORSA's loudest Xtreme sound level with a dual rear exit configuration and polished dual-wall stainless steel exhaust tips.
The Xtreme configuration is noticeably more aggressive than CORSA's Sport system during both cold starts and acceleration while adding only slightly more in-cabin volume. With the dual rear exit layout, this system can deliver up to 20 dB more sound than stock under heavy acceleration, giving the 5.0L V8 a significantly more commanding exhaust character.
