Milltek Decat Downpipe Golf 8 R and Audi S3 8Y

The Milltek Decat Downpipe features a 94mm / 3.7-inch ID turbo outlet that tapers down to 80mm / 3.15-inch pipework, designed for a perfect fit between the turbo and centre pipe on Golf 8 R and S3 8Y models, requiring no modifications. By eliminating both the OEM catalysts and OPF, this downpipe increases power by around 35hp when used with a Stage 1 tuned EA888.4 engine. It also enhances the exhaust note with a more aggressive tone.

Constructed from premium T304 stainless steel, this downpipe features precision handmade TIG welds, ensuring excellent durability. It comes with two options for the cat-back connection: one for OEM cat-back systems and one for Milltek cat-back systems, which are made in the UK.
