i dont no much about exhaust systems so can someone recommend something good. I heard about cat back is that a good idea or what else is there.
The best is a very QUIET system since the Celica sounds like a giant fart cannon instead of cool with a loud muffler. Unless you want to live a lonely life with no women keep it silent since women aren't into fart cannons Get a Mustang for the cool sound you are seeking. .
Cat back. Is only the cat and muffler. The most effective part of the exhaust system for aftermarket is the start of the exhaust the extractors/headers. Get that as well as in a full exhaust. Start with headers only and you will feel a little difference and a K and N filter or any other brand of cotton. Get catback after the headers it will become a full exhaust system or if you got the money get it all at once. Keep the diameter 2inch to 2.5inch any more is no good for a NA engine. Big diameter is only good for turbo cars.
