Product Description

The CORSA 21040 Xtreme Cat-Back Exhaust System is a premium performance upgrade engineered for 2018-2023 Ford Mustang GT models with the 5.0L V8 engine that do not have the active valve exhaust option. This direct-fit system replaces the stock exhaust from the catalytic converter back with a 3.0" stainless steel pipe and dual rear exit layout that enhances both performance and exhaust tone. CORSA's patented Reflective Sound Cancellation (RSC®) technology is built into the design to deliver a deep, aggressive exhaust note under acceleration while keeping drone to a minimum during cruising.

Constructed with mandrel-bent stainless steel tubing and outfitted with twin 4.0" polished Pro-Series tips, the 21040 exhaust improves flow by up to 48% and reduces weight compared to the stock system. The aggressive Xtreme sound level makes it a popular choice for Mustang GT owners who want a bold exhaust note and enhanced performance without sacrificing comfort on highway drives. Installation is straightforward with included mounting hardware and instructions, and no welding is required.
