There are a few guys on BB dart who have used them. I think they are just like every other header out there. Sometimes they fit great and sometimes not at all. All depends on you combo and car. I know that the collectors do not go throught the exhaust cutouts in the trans crossmember,so you lose ground clearance. They are primarily designed with the track in mind and are a slip tube design. I contacted the designer/builder some time ago and have some pics for you.
I think they were designed with aftermarket heads in mind,and if I recall they need a mini starter.
