i was looking to spend around 400 for my exhaust, i found a borla 2.5" cat back from modern performance, did you say what i need to add more boost, also sorry for all the questions but what did you use to cap off your intake nipple from where you put that breather. also, i only have the mods that i said earlier and my gas milage is absolutly horrible, it got bette once my intake was put on, im getting 190 miles out of a tank of premium, and i think my tps might be going out, is this normal?
