i got a few questions about performance parts here. im kinda new to all of this, but i was told that a "turboback" is a much better exhaust then getting just a cat back, with the full up and down pipe. i was trying to see what is a good brand to get. and whts usually the general price range for one. and any other suggestions like blowoff valves, AP , anything else that would be usefull. im sure im missing some stuff. but its 5am and i r tired lol. but any help would be very greatful. thanks.
