I've posted this before somewhere, so I just cut and pasted it in here, but try some of these sounds. I pretty much only listened to axel back exhaust (easy swap) without any changing of the stock H-pipe or headers etc.

Welcome.

Sound is really a personal thing and many people have different opinions on what would sound good. Listen to some sound clips and go to a few swap meets in person. I too have been looking for the perfect sound - actually obsessing over it. Tried one exhaust which sounded very good (FRPP stingers), but was a little loud for me and not quite what I was looking for, so I kept looking. I have recently ordered the FRPP GTA mufflers and will try these out.

Here are a few of my impressions:

Flowmasters are a chambered aluminized muffler, sound good, slight louder than stock at idle, slight deeper, wide open throttle (WOT) scream pretty good, but not excessive. Slightly tin-cannish (many people like). They don't have as much of the original flowmaster sound, since they were trying to minimize drone which can happen in these cars at 1300-2100 RPM. A few sound clips.

IMCOs are chambered aluminized and have true old throaty muscle car sound (old Flowmaster), Extremes moderately loud, Pros not as much - tradeoff is more drone.

Borla Stingers = FRPP (Ford racing) are straight through stainless type, and have an aggressive wonderful sound, deep, mod loud, mod drone peaking at 1800 RPM. Aggressive scream at WOT. I had these but really wanted something just slightly louder than stock with not as much drone and more mellow sound. Alot of people have these and the fit is good, but there is moderate drone.

FRPP "GTA' mufflers (made by Supreme Performance). Ford Racing sells these which are standard equipment stainless with X-pipe on the GTH and Shelby Mustang. Slight deeper, slight louder than stock. I have yet to hear a good clip with them on stock Mustang H-pipe but I hear it is similar. Here are a few with the X-pipe on the Shelby GTH:

Corsas are slight expensive stainless, straight through design stainless. Not much louder than stock or around town, but really scream at WOT and absolutely no drone. Alot of people like these, but don't expect muscle car sound down low.

SLP loudmouths - enough said. Straight through design, Very loud. Wicked. Many clips if you do a search

There also other muffler that I did not look much (JBA, Pipes, ...), and many people change out the CATs, Powerchambers, headers, etc which can totally change the sound. I did not want to do anything but change the axel back so that is all I looked at.

Enjoy and good obsessing.

thanks for all the help guys. the stock exhaust is actually quite impressive on the new GT's. and now that i'm getting some miles on the car (close to 4K) the mufflers are starting to break in and get a good rumble to them. if there's no power gains from a muffler swap then i'll probably do the CAI and tuner first then mufflers on down the line
