DC Sports Y pipe for the 350Z/370Z/G35/G37 is constructed from premium 2.5" Stainless steel mandrel bent piping. Tig welded and mated to CNC machined flanges, this will bolt directly to your OEM equipment, making installation quick and easy. The larger diameter piping allows for increased exhaust flow, leading to improved performance. Our Y-pipe eliminates the factory flex section, removing the risk of leaking flex sections while improving ground clearance.
