ef4life, how many horsepower you think your exhaust is now pushing to the wheels?

 

go look around at muffler shops and see what price it will be to put a catback on there.....on my old cobalt, i had a flowmaster put on there...for 120 bucks for muffler and installation, saved up money and went to get them to replace the pipe between the cat and muffler(for a catback) price was 50 bucks, but i added a resonator so it was 90. so about 200 bucks for a full catback 2.25 ....if you just put a muffler on there, especially a straight through one, you will sound like crappy rice. the piping is so small its gonna be high pitched, if you put a whole exhaust it will be really deep and a lot better.
