down pipe

  1. Engine Modifications
    Hi everyone, Few quick questions.. I have a 18’ WRX which I purchased 5k miles ago. It had a Subispeed axleback exhaust and wheels. I’ve added Cobb Big SF and AP my question is I just purchased a Cobb catted resonated J pipe and wondering if I just wait to put it on or install it this week...
  2. Personal For Sale & Wanted
    I ended up not needing the Perrin down pipe and never got a chance to even install it so it is still brand new. http://www.clubwrx.net/forums/sws-local-sale-only/134340677-perrin-subaru-wrx-sti-catted-downpipe-down-pipe.html In case anyone was wondering the cost without looking at the link...
  3. Engine Modifications
    Hey any of you think if its worth getting just the down pipe on a stock exhaust for 04 WRX? Will it make any performance changes or sound improvements?
