I didn't dyno it beforehand like I wish I had. They're supposed to make 330-350 at the wheels stock, which I'm assuming mine was on the high end. There was only one problem I encountered with the headers, the primary that passes by the steering shaft will need to be dented to clear. Other than that, they look great, the welds are holding up excellent, they make such awesome sounds, and it is a worthwhile mod

What did you make before the headers? Do you like the OBX pipes so far?

Thanks
