    SW Headers

    Purchased this system including the long tube headers and am 100 satisfied. I listened to many systems but you never really know until you sitting in that driver seat. First I like a little rasp in the sound but enjoy the pure muscle sound. These hit the mark perfectly. Best sounding system I have heard. Sure that's coming from me, but when your at the shop with all the other mustang owners and they say that's what I should have put on mine that tells it all. These will not disappointment.
