hey all, this weekend im going to pick up a car im purchasing. a 04 2.5 body with a sti engine. i saw that it still had a stock exhaust on it. i want to order a aftermarket but im not sure if i should be looking for one thats made for a sti or 2.5rs. or if it even matters. its all the same body right? how reliable are these engines? lots of other people are saying they went through a couple engines already. i thought sti trannys are the best.
