  1. Up Pipe Concern

    Engine Modifications
    I own a 2005 WRX and am looking to mod it slowly. I have been doing research and think that the up-pipe would be a great place to start.

  7. DETAILS on IL emissions test!!!

    North Central States
    PASSED TODAY!! YADDA!! I was nervous my baby would spit a 'fail'... SO -- IL is no longer using the tailpipe sniff test... at all, never again. They solely did a 20 second OBDII scan. As long as you don't throw a CEL or readiness codes, you are golden. I have a seriously modified exhaust...
