I'm looking at this Flowmaster exhaust for $280 + shipping......
and also this mac one......

for $300 + shipping....
Which one would be a better exhaust system for my 2002 GT 5 speed? By better I mean more power, and i guess the loudest. Would both or any void warantee? All I have right now is K & N drop in filter.
Also, does anybody communicate threw AOL Instant Messanger? It's a hell of a lot faster then talking through message boards...Thanks again...
