Seat Leon

The SEAT Leon is the sporty compact of the Spanish brand, a technical twin of the Golf and Octavia, also available in high-performance Cupra guise.

Fitting a Milltek performance exhaust to the Seat Leon means unlocking more from its engine: the sound gains character, weight drops versus the original and throttle response becomes more immediate — all in T304L stainless steel, made in England and tested at the Nürburgring.

For the Seat Leon, Milltek's catalogue includes: Additional parts, Cast Downpipe with HJS High Flow Sports Cat, Cast Downpipe with Race Cat, Cat-back, GPF/OPF Bypass, HJS Tuning ECE Downpipes, Large Bore Downpipe and Hi-Flow Sports Cat, Large-bore Downpipe, Large-bore Downpipe and De-cat, Particulate Filter-back. Exhausts with road homologation state so in the product description and are delivered with the relevant certificate.

Browse the products below to find the exhaust compatible with your Seat Leon. Looking for another Seat, find the full range here: All Seat models by Milltek.
