Rated 5 out of 5 by from Very loud!!! Pur based and installed the Roush axleback for my 2018 Mustang with a resonator delete and all I can say is WOW!!! Personally I love the way it sounds it's got some rasp but no drone at all. Its definitely not for everyone though. Install took 30 minutes with a lift and sawzall and it fits like a glove.

Rated 4 out of 5 by from Great for the value but..... Great for the value. Very nice product and look. Easy to install. I kept my factory resonator. A little more power and throttle response. No drone. Very cool at idle and cruise. But very loud when you kick down or drive agressively

I noticed that the description stated that this system will not fit 2015-2017, regardless of valence. Do you know the reason why it will not fit? Different hangers, different dimensions, etc. Thanks.

Asked by: TonyT
Dimensionally they are very different.

I have a 2018 Mustang GT with the active exhaust system. Will this exhaust fit my car? I know that I would lose my active exhaust, but will it fit? Also, does it come in black tips instead of the crome?

Asked by: 2018 Stangit
It would physically fit.
