Remus Non-Resonated Valved Cat-Back Exhaust System for Ford Mustang GT 5.0 V8 (2017+) S550 - Quad 98mm Tips, Stainless Steel, ECE Approved

Performance catback for Mustang 5.0 Coyote S550 with valve control and quad 98 mm outlets

Turn your 6th gen Mustang into the V8 it should sound like with this Austrian-built sports rear system. Crafted from premium stainless with a shot-blasted finish, this straight-through, no-centre-resonator setup unleashes a deep burble at idle, a crisp bark under load and a refined cruise when the factory-controlled valves are shut. ECE homologated and engineered to work seamlessly with the original drive mode valve operation, it delivers everyday civility with track-worthy character when you want it.

We have installed this upgrade on customer cars and our own builds at MJ Modifications. Fit and finish are superb, tone is addictive and feedback has been consistently positive from owners who wanted more character without the tinny rasp. If you are searching for a Mustang GT exhaust upgrade in the UK, this is the premium choice that looks as good as it sounds.
