Upgrade your exhaust system with this 3.5" Decat Downpipe for the Volkswagen Golf R MK7/MK7.5 and Audi S3 8V, designed to replace the restrictive factory OEM downpipe that commonly limits exhaust flow and performance.
We've gone the extra step and started ceramic coating these downpipes as standard. They now come in a black ceramic coat to reduce overall engine bay heat, and increase exhaust flow.
Featuring a 3.5-inch inlet design, this downpipe provides superior exhaust flow compared to the common 3" alternatives on the market, helping reduce back pressure, improve turbo spool, and increase peak power. Precision-manufactured from thick-wall 304 stainless steel and finished in a brushed stainless appearance, this downpipe is built for long-term durability under high heat and performance conditions.
Constructed using 100% TIG welding and supplied with quality hardware and clamps, this unit is a direct bolt-on replacement compatible with both factory and aftermarket cat-back exhaust systems via the included adapter sleeve.
Beware of cheaper, inferior downpipes on the market that use thin-wall tubing — these are prone to cracking, splitting, and premature corrosion over time.
