Remus Valved Racing Cat Back Exhaust for Ford Mustang GT 5.0 V8 S550 (2018-2023) - Non Resonated, 3in (76mm) Stainless Steel, Fastback & Convertible

Remus valve-controlled performance system for Mustang 5.0 V8 S550 - non-res sports sound

Turn your 2018 to 2023 Mustang 5.0 into the V8 it always wanted to be. This Remus valve-operated rear system replaces the factory cat-back with a freer-flowing 76 mm layout, unleashing a harder-edged, motorsport-inspired note while retaining switchable valves that work with the car's original drive modes. Non-res configuration for maximum presence, precision-built in Austria from premium stainless steel for durability, fit and finish you can trust.

We have installed and run this system ourselves and our customers love the deeper idle, crisp upshifts and serious bark under load. Expect a noticeable step up in character and response compared with the stock setup thanks to the larger diameter and low back pressure design, with everyday usability preserved via the OE valve control.
