I was wondering if anybody here is running a test pipe, and for those who don't know what a test pipe is.... a pipe that replaces the catylatic converter with holes for the O2 sensors.
Just wondering if anybody has done this and if there is any noticable power gains.
Active Autowerke sells a test pipe, which they call a track pipe. Mine should be here Tuesday...
AA has dyno charts online...you can check them out and that should answer your questions..
