Vehicle Fitment

Rated 4 out of 5 by from Sounds mean I purchased this cat back about 2 weeks ago, and installed it 2 days ago. Went together very easily and the sound is unbelievable. Not as loud as I would have liked but hopefully once it breaks in it will open up. My only complaint I have is the hanger on the mufflers is too long on the driver side causing the tip to rub the valance. Easy fix but spending $1100 on an exhaust shouldn't result in this issue. Would recommend to anybody with a S550 mustang for easy assembly and pure sound quality.

Rated 5 out of 5 by from Worth the money I bought it a month ago and it sounds amazing! If you want something quieter this isn’t it. In 3rd gear under 1300rpm is about the only time it’s “quiet”. Super easy install and parts came really well packaged!

Do you confirm it will fit convertibles (it's written "Fits 2015-2017 GT Fastback and Convertible" and "*This cat-back exhaust system will not work with convertible". Moreover, what size is the parcel ? I'm thinking about bringing it back to UE by plane

Asked by: Wharfedale
This is not compatible with convertibles.
