034Motorsport Cast Stainless Steel Racing Downpipe, Audi 8S TTRS and 8V.5 RS3

This cast stainless steel downpipe with an integrated racing catalyst suits the 8V.5 Audi RS3 and 8S Audi TT RS with the 2.5 TFSI EVO DAZA engine only. It uses dual 70mm downpipes, 17% larger than the factory 60mm pipes, and a 150mm Euro 4 200-cell racing catalyst in the factory location, which 034Motorsport says helps the catalyst light up quickly. The cast, TIG-welded and back-purged 304 stainless steel build includes an integrated V-band turbo flange, a factory-location oxygen sensor bung that needs no harness extension, OE-style flex bellows and hangers, and a sand-blasted titanium-look finish. 034Motorsport recommends an ECU recalibration to make use of the extra flow, and its in-house car made 577 HP and 538 ft-lbs with the downpipe on its Stage 2 E85 software, against 407 HP and 371 ft-lbs stock.
