"this not only sounds great but the performance is awesome!!!" —Maryanne H from Orlando, FL bought a Flowmaster Exhaust Systems for a 2003 Ford Mustang.
"I think this is a great exhaust system, but I did have some trouble with the fitment.The main problem I experienced was attempting to install the tips. The metal hanger rods would not fit through the hanger rings on the tips, even with very heavy hammering, so I was unable to install the tips. Otherwise, great sounding system." —Patrick M from Alpharetta, GA bought a Magnaflow Exhaust Systems for a 2003 Ford Mustang.
"Just remember to jack the body away from the frame to get the pipes in and you should have your new Flowmaster system installed in less than an hour.Great sound, I love it." —Nick S from Rochester Hills, MI bought a Flowmaster Exhaust Systems for a 2003 Ford Mustang.
"Good exhaust. Easy to install. Great sound, though a little louder in the car than I'd hoped for." —John B from Arroyo Grande, CA bought a Flowmaster Exhaust Systems for a 2003 Ford Mustang.
"Installation:Very nice kit made installation fairly easy. If you have any machanical ability there is no reason not to do the installtion yourself. Was able to do the installation with all hand tools in 3.5 hours. Power tools would have cut it in half, plus I had to do some modifications to the tips.Only problem I really had was the tips. I had re-drill and boure out the welded mountings as they were way too snug to get the mounting rods in them. Since, I didn't want to ruin the tips this took some time, but would have been faster if I had a 1' drill bit. I initally figured this had to do with a temparture change and the pipes just expeanded, but even after putting the tips in the freezer for 15 mins didn't help.Sound's nice!!! A bit louder then I thought it would be from the reviews, but not an issue. Sounds like a kitten crusing on the HW. Sounds like a modified Cobra in the city.Performance, defenetly getting more HP. After one week. I got slight more gas milage, but don't think this has anything to do with the exhaust. I just stating using brand name gas again, and added 6 lbs of air pressuer in the tires over the door rating. Had alot of rain this week and the added tire press seem to perform better with my tires. Their max rating is 45 door rating is 34. So I'm running them at 40 lbs. Gas milage went from 17.2 to 17.9 some route I always do, but still too many other factors to state the exhaust improve gas milage. But I would bet if I was not punching the gas as much to hear the new exhaust, I would have topped 18." —Robert P from Sicklerville, NJ bought a Magnaflow Exhaust Systems for a 2003 Ford Mustang.
"sounds good. looks good. adds hp" —James J N from Burlington, WI bought a Borla Exhaust Systems for a 2003 Ford Mustang.

"it sounds great until you go over 3000 rpm's then the sounds dies off. but until that, it sound great and i can fell the gains in power." —Robert G from Philadelphia, PA bought a Heartthrob Deep Tone Cat-Back Dual Exhaust Kit for a 2003 Ford Mustang.
"I was extremely happen with the sound of this system!" —Ron H from Mesa, AZ bought a Flowmaster Exhaust Systems for a 2003 Ford Mustang.
"Great sound and looks. Borla is first quality start to finish. May cost a little more but worth every penny." —Larry M from Henderson, NV bought a Borla Exhaust Systems for a 2003 Ford Mustang.
"Even better sounding then I expected. I have never heard a better sounding exhaust on a mustang, sounds just like the early 90's GT's. I like that the tips are welded to the pipes so there is no rattling around and everything fits nice and snug. Looks and sounds great, bolted up real nice to the BBK o/r pipe. I would highly recommend this combo (o/r x-pipe & Flowmaster 40 series) to anyone looking for that great unmistakeable Flowmaster sound!" —Tom H from Des Plaines, IL bought a Flowmaster Exhaust Systems for a 2003 Ford Mustang.
