DESCRIPTION
Upgrade your exhaust system with this 3.5" Decat Downpipe for Volkswagen MK7/MK7.5 Golf GTI, Audi A3 8V, and TT MK3 (FWD models). Designed to replace the restrictive factory OEM downpipe, this high-flow design significantly improves exhaust flow and helps unlock increased power and faster turbo spool.
Featuring a 3.5-inch inlet, this downpipe offers superior flow compared to the common 3" alternatives currently on the market, reducing back pressure and improving overall engine efficiency. Manufactured from thick-wall 304 stainless steel and finished in a brushed stainless appearance, it’s built to withstand high temperatures and demanding performance conditions.
Constructed using 100% TIG welding and supplied with quality clamps and hardware, this downpipe 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 made from thin-wall tubing, which are prone to cracking, splitting, and premature corrosion over time.
