    1 Top Rated Question

    Long story short. Had to buy 2018 mustang that came with active valve exhaust. Can this cat-back without active valve be installed on this mustang. I like the "soft" throaty sound this makes and have no desire to manipulate its tone. I have concerns about the computer. If this will work, should I preset the computer valve settings for a particular mode before install. I know of the magnaflow valve that's designed for said system but I don't know what exhaust notes I'll get with that option. It would have been simpler to have ordered a mustang without active exhaust but there was a midyear change, 2018 to 2019, and my color choice was discontinued! So I had to get what I could get. Sorry for lengthy question. Thank you.

    • Yes, you are able to use this exhaust with the 2018 GT with an active exhaust. You will need an added part made by Magnaflow in order to have this exhaust set up work properly on your Mustang and you will be able to find that part here: With the added part for your Mustang, you will retain the factory active exhaust functions as well as keep the sound/tone of this exhaust that you like.
