hey, I have a 93 acura hatchback automatic i am really looking into purchasing an AEM cold air intake for better performance, hence i have heard nothing but good things about it. I also am hearing an odd sound coming from my stock exhaust system (very possible there is a hole in it), and am eagerly wanting to replace it with a GREDDY MX CAT. BACK EXHAUST. advise me if i'm wrong or any better advice on any thing... i would like ne body to reply if you are looking for a good site, i found a well priced performance parts page... www.adventon.com later
