Remus Turbo-Back Non-Res Exhaust for SEAT Leon Cupra 300 Mk3

Unlock the soundtrack and flow your Leon Cupra deserves with this Remus full system from turbo outlet to quad tailpipes, engineered for the 5F platform 2017 onwards with the CJXC 2.0 TSI engine.

Handcrafted in Austria from premium stainless steel and finished in a shot-blasted texture, this high-flow upgrade replaces the factory pipework from the turbine housing all the way to the rear, delivering a sharper throttle feel, a deeper motorsport tone and beautifully finished quad 76 mm straight-cut chrome trims. The straight-through, non-res centre section and mandrel-bent 70 mm tubing reduce restriction, helping the turbo breathe while keeping cabin refinement on a cruise. The integrated 200 cpsi sport catalyst balances performance with compliance, and the Left and Right split exit gives a purposeful OEM-plus look.

We have installed this system for Cupra owners across the UK and the feedback is consistently positive. Customers praise the build quality, the fit, the aggressive yet refined sound and the noticeable improvement in response.
