Remus Sports Cat-Back for Seat Leon Cupra MK3 5F 2.0 TSI CJXC (2017 onwards) with Twin 142 x 72 mm Angled Chrome Oval Tips
Give your MK3 Cupra the soundtrack and flow it deserves. This Remus straight-through, non-resonated sports cat-back is a direct-fit performance upgrade from the catalytic converter back, delivering a richer, motorsport-inspired tone, crisper pedal response and lower restriction while remaining ECE homologated for road use. Precision-crafted in Austria from full stainless steel with a bead-blasted finish, it is built to last and to fit the 5F platform perfectly.
We have fitted this system for customers at MJ Modifications and feedback has been outstanding. Owners praise the deep idle, clean upshift bark and the freer-revving feel that comes from the 70 mm bore pipework and high-flow design. If you are searching for a premium MK3 Cupra exhaust upgrade that looks, sounds and performs superbly, this Remus sports system is a winning choice.
