Remus Sports Cat Back for Seat Leon Cupra 5F 2.0 TSI CJXC 221 kW 2017 onwards, dual outlet with angled oval chrome tips

Unlock the sound and character your Seat Leon Cupra deserves with this premium Remus stainless steel cat back system. Featuring a resonated centre section paired with a non-resonated rear section, it delivers a purposeful Cupra tone and improved gas flow while remaining ECE type approved for road use. The twin oval 142 x 72 mm angle cut chrome tailpipes fill the valance beautifully for a factory-plus look.

Hand built in Austria and finished in a shot-blasted surface, this 70 mm bore performance exhaust is lighter than stock, reduces back pressure and is engineered to fit perfectly on the 5F platform. We run Remus systems on our own cars and our customers consistently praise the fit, finish and sound quality.
