Scorpion Cat-Back Exhaust System - Renault Megane RS (Mk4) 280 / 300 Trophy - 76mm
Scorpion's cat-back system for the Renault Megane RS (Mk4) replaces the factory silencer section with 76mm (3") T304 stainless pipework and uses the OE tailpipes, so it sits neatly in the factory diffuser. Scorpion lists it for the RS 280 GPF model and the RS 300 Trophy, and it fits the OE front section or a Scorpion front pipe.

Resonated versions keep a centre silencer for a deeper, more refined tone with less cabin drone; non-resonated versions replace it with straight pipe for a louder, rawer note.
Note: Australian-delivered Megane RS 280 and 300 Trophy have no GPF. Scorpion lists this version for the Trophy and for GPF-equipped (UK/EU) RS 280; for an Australian RS 280, Scorpion's non-GPF RS 280 cat-back (SRN031 / SRNS031) is the matching version – contact us to confirm. Fitting requires cutting the OE silencer, unplugging the rear parking sensors and removing the rear valance; the OE valve is removed on the Trophy. Installation by a professional is recommended.
