The T1R O2 Housing - Down Pipe is the key to unlocking the full power potential of the Evo X! Our own tests, and those of other tuners have confirmed that aftermarket down pipes do not make significant power gains at all as the stock down pipe is very efficient already. However, when the down pipe is combined with the O2 Collector Housing to make a one piece unit, the exhaust flow velocity is greatly increased. Substantial power gains are instantaneous, and there is even further potential for more power to be gained through tuning.

Note: ECU tuning is strongly recommended! The T1R O2 Housing - Down Pipe can cause overboosting, which needs to be addressed through tuning.

The Version 2 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 pipe if the second bung is not used.

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