I am about to put a full exhaust system and headers on my 06 GT and I wanted some opinions on which exhausts you guys liked the most and which headers I should use because honestly headers are not my forte. I've listened to some sound clips but sometimes the quality isnt that great, but it does seem that the flowmasters actually dont sound as good as some of the others. Thanks guys your help is appreciated

 

I love my Flowmasters, cant go wrong with them, they sound amazing! I always get the thumbs up wherever i go.

For headers, it depends, recommendation, longtubes. Brand name I've always trusted, Hooker!

 

IMO, you need to decide on the headers/midpipes before you choose the axlebacks. Based on all the input I have read, as well as my own experience, if you go with any header/midpipe setup that eliminates the stock cats, you will probably get the dreaded trumpeting. Then you will need to get specific axlebacks to negate that effect. If you get shortys, and keep the stock cats, then your choices on axlebacks are wide open. Just my 2 cents.
