    Does driving a car without mufflers hurt the engine in the long run? I had an '11 Mustang GT that I ran with only an x-pipe with no mufflers or resonator.After about a year, the engine developed a serious knock that could never be explained by a number of mechanics. One mechanic said I should never remove mufflers and resonator because every engine need some back pressure. What's your take on this?

    • We would not recommend this setup as this can be bad on the pinon rings and may also not be legal in your area.

    With a GT350 Rear Valance Diffuser on my 2017 GT, would this then be compatible with the 2017 model?

    • Unfortunately we have not tested this exhaust with the 15-17 Mustang GT models so we would be unable to guarantee fitment.

    I have active exhaust on my 2018 ,Will I be able to install this axle back?

    • Unfortunately this exhaust will not work with 18-19 Mustang GT models that are equipped with active exhaust.

    I have a full 3 inch system now from the headers back. I want to change my axle back to this, but these seem to have 2.5 inch pipes? Would i need a reducer to make these connect to my 3 inch pipes?

    • If this MBRP Black-Series Axle-Back Exhaust was to be paired with your existing 3" exhaust system, you would need a 2.5" reducer in order for them to work with each other. Minor modification and cutting may be required for this kind of application.

    Does this system cause a lot of cabin drone?

    • You will experience some cabin drone with this system but it will not be excessive and will mostly be noticeable at higher speeds.

      Loud and louder

      I have catkess headers installed but kept the stock resonator and axle backs. I got these and dang they are loud at cold start. A bit excessive. They low grumble is nice but it will upset my neighbors during the early mornings. With stock headers and resonator I imagine it sounds amazing. There is some drone at certain RPMs but nothing horrible. Easy to install. Took under an hour with stands.

      Deeper Rumble

      I listened to a lot of exhaust videos online. This gave the rumble I was looking for without overdoing it. I could not have had the sound custom built any better. Thanks to American Muscle for the review video!

      Great exhaust

      Easy install and sounds great! It really wakes the car up and a tiny bit of drone at low speeds but I mean it’s a mustang. You are suppose to hear that 5.0.

      Great sound for the money!

      Easy install, takes about an hour if you have a lift. Sounds great and is a lot louder than expected but not too crazy. I would recommend to anyone who wants a more grunt out of there 2018 Mustang GT.
