    Shelby offers a Watts link option for these GT500s'. I have the Shelby Watts Link. Will this System work with that Watts Link? The stock exhaust seems to have plenty of room over the axles.


    • The Magnaflow Street Cat-Back Exhaust has not been tested with the Shelby Watts Link, but this is expected to fit.

    Will the Magnaflow Street Cat-Back Exhaust w/ Quad Tips (13-14 GT500) fit my 2014 Mustang GT? Thank you.


    • If you have a Performance Package Mustang with a Roush quad-tip rear valance, you will be able to install this Magnaflow Street cat-back on your GT.

    How is the fitment on lowered vehicles?


    • The Magnaflow Street Cat-Back Exhaust w/ Quad Tips (13-14 GT500) should not be touching the ground with a lowered vehicle to a certain extent. If you are touching gravel, then there could be some issues with the exhaust possible hitting. Other than that, this exhaust shouldn't give you any issues!

    • There should be no issues of the exhaust not being align. There is a possibility of a bent hanger that could affect the position of the exhaust. If you are still having issues, I suggest taking it to a shop and seeing if they can help.
