Test pipe is one of my favorite budget mods, was wondering if anyone was selling a bolt-in unit. Any thoughts/expieriences with it?

 

Cheapest option would be to have a muffler shop make you one. Minimal gains on NA setup.. Be sure to get a 5-wire o2 simulator if you don't want the CEL coming on.. The 3-wire ones don't seem to work with this car. The ECU randomly does some extra checks to make sure you have one
