350Z HR / 370Z / G37 VHR 2.5" Manifold (Header) to Testpipe or Cat Flange
The AAM Competition laser cut T-304 Stainless Steel 2.5" VQ37VHR or VQ35HR Manifold (Header) to Testpipe or Cat Flange is perfect for building a custom exhaust or repairing an existing, damaged exhaust. This is the flange that connects the manifold (header) to the factory cats, test pipe, or high flow cats.
These flanges accept 2.5" OD tubing (the most popular exhaust tubing size used for test pipes and high flow cats on the 370Z / G37 / 350Z HR.
These flanges are made from true T-304 stainless steel -- don't settle for mild steel flanges which will start to rust in short order.
Flanges sold individually. We also sell the gasket for this flange here.
