i have always used bbk and have never had a fitment problem.. i love the way that they sound/look and how they hold up.. i also have used mac and i like their 3 piece design.. it gives you more adjustments to getting it tucked up on the car better so it doesn't drag.. espically if you lower your cars like i do... hehe
I have bbk with no issues.when you ard ready 4 header than u need schooling.i have bbk lt and didnt know trans cant be pulled im on my 3rd tob and header install is a pita.these guys will help better than u can expect.
I had BBK's on my last Mustang. They were nice, but do pose problems with the tranny. I think I am going to either run the Bassani Mid-Lengths or the SLP's
