This exhaust was a great choice! If you're looking for an exhaust that isn't too loud but still has a great deep tone, this is the one for you! It isn't too loud where it scares people but it's enough

    long term update

    Great fit and sound, but does not hold up long term. A baffle came loose in one of the mufflers after 3 years (rattles) and a pipe rusted through at the H pipe joint at 6.5 years. This is with full time use in Kansas weather.

    Gives your V6 a deep sound

    I have installed this along with BBK Headers and off-road pypes x-pipe and with these 50 series give my 3.8 a nice deep tone that i love. Fitment...take some elbow grease to get it fit nice, i had the back exhaust slightly touching my axle but not too big of a deal. Real great product, good shipping and good quality. I would deff buy this again. The tips look great out the back and the sound is deff a head turner. Thank AM!

    A great product for an amazing price.

    This exhaust was a perfect fit for my '02 GT. I jacked the car up and was still able to install it with no difficulties. It looks great ad sounds nice a throaty, just like a mustang should. It isn't very loud so you can actually hear other things inside the car, but is still loud enough to stand out from others.
