Cat back systems? Which one are the best?
 

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.

corsa is a straight through muff...
so that means its gonna be LOUD... like slp catbacks...
i know nothing on corsa... never heard of it til now

want something quieter...
i would say flow master 70's or like...
something chambered...
or borla (chambered)
I LOVE MY BORLA but thats $$$...
I recomend borla for the performance + sound

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.

yeh... i read that... googled it...

well... those will be loud...

so if ya want something quiet that gets Loud when ya get on it so with flow masters... they sound really good... ya'll probably only need the muffs

from what ive heard borla is the shi* if you can afford it

borla is very good...the thing is about borla if you kno anything about anything you can pick the borla exhaust tone outa anywhere
