Give your 5.0L-powered F-150 a deeper, more aggressive exhaust note 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 6.5-foot bed and 122.8-inch wheelbase, this system combines 3.0-inch 304 stainless steel construction with CORSA's loudest Xtreme sound level and a balanced dual rear exit layout.
CORSA custom tunes its No Drone RSC® Technology specifically for the F-150 V8, helping the system deliver an aggressive exterior exhaust note while limiting unwanted in-cabin resonance. The dual rear exit configuration can be up to 17 dB louder than stock under heavy acceleration, giving the 5.0L V8 a much more commanding sound without sacrificing the refined cruising character CORSA is known for.

Xtreme Sound Level
CORSA's Xtreme system is designed for F-150 owners who want the most aggressive exhaust note available in this configuration. The Xtreme sound is noticeably stronger than the Sport system during both cold starts and acceleration while adding only slightly more in-cabin volume. With the dual rear exit layout, the system can produce up to 17 dB more sound than the factory exhaust under heavy acceleration.
No Drone RSC® Technology
CORSA's best-in-class No Drone RSC® Technology is custom tuned specifically for the F-150 V8 engine. The system is engineered to control the unwanted frequencies responsible for exhaust drone while preserving the aggressive tones enthusiasts want to hear, helping maintain a more comfortable cabin during cruising.
Dual Rear Exit Design
The 21143 uses a dual rear exit configuration with one 4.0-inch tip positioned on each side of the truck. This balanced layout gives the F-150 a traditional performance-truck appearance while pairing naturally with the more aggressive Xtreme sound profile.
Polished 4.0-Inch Tips
Each side of the system is finished with a polished 4.0-inch dual-wall stainless steel exhaust tip. The straight-cut design provides a clean, modern appearance while giving the rear of the truck a more substantial performance-focused look.
304 Stainless Steel Construction
CORSA constructs the system from 3.0-inch 304 stainless steel for excellent durability and corrosion resistance. Backed by more than 20 years of development around CORSA's Science of Sound©, the system combines durable construction, application-specific acoustic tuning, and aggressive performance styling. CORSA Performance exhaust systems are proudly made in the USA and backed by a Limited Lifetime Warranty.
