Description
For 2021-2024 Ford F-150 5.0L V8 – Regular Cab – 8FT Bed – 141.5" Wheelbase
The CORSA Performance Xtreme 3.0" Cat-Back Dual Rear Exit system is engineered for Ford F-150 Regular Cab with 141.5" wheelbase and 8-foot bed. This system replaces the stock exhaust from the catalytic converters back, delivering aggressive performance and commanding sound.
The Xtreme sound level is the loudest CORSA Performance exhaust available. It produces a deep, aggressive V8 tone, noticeably more pronounced than the Sport system on both cold start and during acceleration, with minimal in-cabin drone. Dual Rear Exit configuration achieves up to 20 dB louder than stock under heavy acceleration, giving your truck a bold, high-performance presence.
Constructed from 304 stainless steel with mandrel-bent tubing for optimized airflow, the system includes dual-wall stainless tips with polished or optional black PVD coating. It reduces overall system weight by approximately 13 lbs compared to stock and installs with a simple bolt-on design—no welding required.
All CORSA Performance exhaust systems are acoustically tuned using 20+ years of proprietary Science of Sound technology. Proudly made in the USA, each system comes with a Limited Lifetime Warranty.
