        2002 sonic blue gt

        Easy install. Only had to cut down one pipe for fitment. Sounds great with my sve cat delete x pipe. For the price definitely recommend. Took about hour and a half to install. Installation tip if you're doing it on the ground, remove rear wheels pipes slide right over the axle.

        Great product at a great price

        Good bang for the buck - most economical system on here. Fit was decent. Just wish the tips were a little larger diameter. Mellow sound, not too loud.

        Awesome sound

        I ordered and had it quickly. Went together easily. It has the sound I was looking for. Together with the BBI shorty headers it sounds like a mustang should.

        Great overall product

        Install was fairly easy, and it sounds great. Not the loudest exhaust out there, but for the price you just can’t beat it.

        Did not fit

        I bought this for my 04 mustang gt and the arc that goes around the axel was too big, almost like it was ment for a truck. But ended up buying an arc from AutoZone and using them anyways.

        1 2004 GT - Keane Installation Time: Afternoon

        Terrible

        The product requires heavy modification if your vehicle is lowered. The exhaust does not go over the axle correctly and your tips will not align properly. After cutting and welding on multiple different pieces I got the system to fit and it sounded terrible. I have no cats and the system still makes no noise. Very disappointed, you get what you paid for.

      Does the SR kit drone on the highway with the stock H pipe for the GT? I like to change my stock mufflers but also want to have a conversation in my car with a passager at 70 MPH. Thanks!
