Looking to get exhaust for my 05 GT.I hear Borla has a great sound to them. Can anyone give me some input?

 

If you have the funds, Corsa makes a droneless muffler that is a little louder and deeper when new and quite a bit louder and better after about 500 miles.

For a truely mean sound, match them with a pypes off-road h-pipe:

Yup do a search on you tube with all the brands you want to hear. I have magnaflows with magnapacks (straught thru design) and they are great. Very little drone (1800 RPMS for a sec) and they sound like NASCAR @ WOT! I love it!!!! JMO J link to website...http://www.magnaflow.com/
