REMUS performance rear box with twin oval chrome tips for Seat Leon 5F ST 2.0 TSI Cupra 2017–2018

Give your fast estate the soundtrack and finish it deserves. This REMUS axle section replaces the factory rear box on the Seat Leon 5F ST Cupra 2.0 TSI and delivers a fuller, deeper tone under throttle while remaining civil at a cruise. Precision built in Austria from stainless steel with a shot‑blasted outer, it uses 70 mm pipework and striking twin 142 x 72 mm angled, oval chromed outlets that sit perfectly in the valance for that OEM plus look.

We have fitted this system on customer cars and the feedback has been consistently positive: great fitment on OE mounts, quality welds, noticeably richer sound without drone, and a premium finish that lasts. ECE type‑approved for road use and designed for non‑OPF cars, it is a straightforward, high‑quality rear section upgrade that enhances both tone and styling.
