    Disappointing Sound

    It makes a humming noise that you can hear inside the car cabin that is really annoying. After trying it for just one day and trying to return it, the seller refused to accept the return because it had already been installed. I recommend future buyers listen to the sound in person because it sounds good on the phone and then when you install it it is very annoying not because of the loudness but because of the horrible humming sound.

    2024 Mustang Ecoboost MBRP Race Exhaust

    Item arrived in a quick and orderly fashion, everything was packaged very well. Install was straight forward and easy. Tone and sound of the exhaust is vastly better than the stock unit. Bit of drone at about 2k rpm but that was expected. Overall greatly satisfied. The videos do not do it justice, cold starts are beautiful with this unit.

    Don't let the words "race version" scare you.

    This exhaust produces a deep mellow tone that isn't too loud. Sure, there's no mistaking you have a 4 cylinder under the hood. But, your Mustang will never be mistaken for a ricer Honda Civic going down the road.
