hi I'm picking up my new car hopefully Thursday. Its a 1998 turbo wagon and covered 71000 miles, full service history and not long had the cam belt done, i want to modify it a little but am not hunting for big BHP so am really just wanting a better exhaust, louder as i love the noise these engines make and want to enjoy it a little more, also i guess a better panel filter and maybe a dump valve and that would be about it. So and help or point in the right direction would be great thanks for any help
