your numbers on a mustang dyno or dyno jet?i have macs lts (mid-lengths) and i have no problems with fit or finish, and the install wasnt bad at all. I dynoed 305whp and 317wtq with these headers, an offroad mac x pipe and an intake and tune. Here is a link to my thread about the headers which has a video and a review.
