I searched around, but once again the sheer quantity of useless hits is staggering.
I just bought a bone stock '02 WRX wagon, and want to A) Make it sound a bit meaner and get a few extra HP and B) Get an aftermarket up-pipe on it to eliminate the possible cat issues.
Which would you do first, a 3" CBE, or an up-pipe and down-pipe ? My experience tells me that a Up-pipe & Down-pipe would make the most sense (eliminate cats 1st, then do CBE). Thoughts ?
What up-pipe is recommended ? Some have flex sections, and some do not. I like flex, but also know that it can sheer off. Any input is welcome, because I'd really like to get the ball rolling on this.
Thanks a lot, guys.
