Can anyone rank the best Cat-back systems for the 2005 GT. I have Mac long tube headers, prochamber H-pipe w/hi-po cats and the Mac Catback system right now. I've had a lot of problems with it ie doesn't fit right and rattles. The power is good, but I don't really like the sound. It is so loud at highway speeds that your ears are ringing after a long trip. I'm thinking about getting my money back on the h-pipe and cat back system and getting a Corsa x-pipe and cat back system. What can you tell me about the Corsa products. Any help would be appreciated.

and check it out. I've been told they are very good. The MACs sound great, but they just don't seem to fit right, and the hi-po cats that come with them keep making my engine light come on. I don't mind them being loud when I get on it, it's just cruising on the highway in fifth gear that starts to make your ears ring. I am going to keep my MAC long tubes.

Thanks for the response.
