Remus Axle-Back Back Box Upgrade with Quad Straight-Cut Chrome Tail Trims for Seat Leon MK3 5F Cupra 2.0 TSI 221 kW (2017+, CJXC) - ECE Approved - Non-OPF

Give your MK3 Cupra the soundtrack and presence it deserves. This Remus rear section transforms the character of the 2.0 TSI with a deeper, more purposeful tone and a sharp, motorsport-inspired finish. Hand-crafted in Austria from full stainless steel and media blasted for longevity, the twin left and twin right silencers pair with four 76 mm mirror-finish straight-cut tips to fill the diffuser perfectly and elevate that OEM plus look.

We have fitted and run this setup ourselves and customer feedback has been superb. Fitment quality, sound quality and the overall refinement are exactly what you expect from Remus. ECE approval means it is road legal in Europe while offering a more engaging exhaust note and improved flow characteristics.
