Flowmaster Super 40 vs. Original 40
Yea, I'm running the 2 1/2" Dynomax welded and they are loud with almost no restriction. You can easily tell that when you're standing behind the beast and your pant leg is flapping like a flag. But that being said I do have a harmonic right at 2400 rpm so ya just got to stay above or below it. I do love rumbling up beside the Stangs a shaking and a rocking. :burnout:
