The T1R Racing Converter is a fully resonated Test Pipe designed for maximum exhaust flow. The T1R Racing Converter features 76mm (3") SUS304 stainless steel piping. The inner diameter of the T1R is 73mm (2.9") compared to the stock cat's ID of 53mm (2.24"). The T1R Racing Converter includes a resonator to help exhaust noise, both for daily driving, and to help avoid exceeding race track noise limits. This test pipe can be used with the stock down pipe and b-pipe, or aftermarket pieces which can connect to the stock cat, such as the T1R 76S and 90R exhausts. For off-road use only.

Fits Evo X and 09+ Ralliart.

The Version 2 test pipe now includes a second O2 bung for the addition of another wideband O2 sensor for meters or tuning. A plug is included with the test pipe if the second bung is not used.

The Version 1 test pipe, which is identical, except for the second O2 bung, is now discontinued.
