I'm currently running Mac Axle Back Exhausts on my 07 GT, are there any other suggestions or does anyone think I should just keep it as is?

what are you looking for? if you're going for a very aggressive tone, i'd suggest slp loudmouth or any other muffler delete (magnaflows MD isn't that aggressive though) or even boomtubes axleback system isn't bad

Something not too throaty, something that when idling still sounds like it's ready to take off. Do you have any video links of the slp loudmouths?

go to americanmuscle.com they have clips of several exhaust systems...to hear the boomtubes, search youtube for "2007 mustang gt boomtubes"

I have Flowmaster American Thunder Classics and love them, but I've heard they sound similar to the Macs. Why are you deciding to switch?

Stainless Works

Change out to our S-Tube mufflers which are known for a clean race car sound, with a deep rumble at lower RPM's

At first I just had Borla Stingers and received a lot of complements on how my car sounded. I then after watching a ton of exhaust videos online I decided to go with the pypes off road H-pipe and WOW! My car thunders jwhen I put my foot in it, but the drone isn't terrible. I love the set up and still receive complements. The Borla's by themselves were a huge improvement, but now my car turns people's heads.

Recent vid of my ride at a Dyno day. Hopefully, the sound quality is good wherever you are. 06 GT 5-speed with Borla Stingers. Not obnoxiously loud, but still loud enough to have people ducking for cover and kids start crying.
