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.

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

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

Sent two different sized pipes.
I received the package and was excited to install it until I set it up and saw that one of the pieces is 2-3 inches longer than the piece on the other side. The pipes were also dirty on the inside and scratched up. Your better off spending the extra $40-50 on the actual slp website if you want your exhaust to show up correct and in brand new condition.
