The COBB Tuning 3″ Stainless Steel Catless Downpipes are the same downpipes that helped power our COBB Motorsports Redline Time Attack Modified Class GT-R to a Class Championship in 2010! Designed to bolt up to the stock turbos or stock-location upgraded turbocharger kit, this downpipe kit has been rigorously track-tested and proven reliable at power levels beyond 800whp.
Take your Stage2 GT-R with upgraded Y-Pipes to the next level with the COBB Tuning 3” Catless Downpipe Kit. Consistently improve turbo spool-up by 250-300RPM and open the door to maximum stock turbo power output when coupled with complementary modifications including; injectors, fuel pumps, intakes, boost tubes and intercoolers.
These high-flow, mandrel-bent, 304-stainless downpipes remove the restrictive stock catalytic converters for better flow, faster turbo-spool and improved transient response. This downpipe kit is a direct OEM replacement and will bolt up to the stock exhausts system or aftermarket systems alike.
