Sounds amazing
Bought these for my 99 mustang gt. Got these on and man do they sound amazing. If you don’t like something that’s loud and raspy then this isn’t the exhaust to look for. But these came earlier than expected and cheaper than American Muscle!

Wouldn’t recommend
Bought and installed per the instructions. The couplers that connect are not the best. Lost one side 1/2 back and they don’t offer replacement parts. Complete waste of money

Great item
Product as described. Fit on my 2004 Mustang GT and it sounds perfect. JEGS was a great seller to work with and their customer service was exceptional.

Made my son's car sound like a dragster
Put 'em on my son's '99 MGT and was very impressed with the sound and performance. Very easy to install.

A must for 99-04 mustangs !
The media could not be loaded. Sounds amazing on my 01 gt and crackles and pops when down shifting but I do also have a x pipe and long tube headers
