I still want to add boost, but my plan at this point will be to get the car finished first. Roger, it will be similar to Steve's.
The headers are 1.75" and they're uncoated. I'm evaluating what I want to do. Run them as is, cut the primaries and have a local fabricator create stepped headers by welding 1.875" primaries tubes 6" past the flange, or perhaps try a different header all together. We're very fortunate to have Art Morrison involved with Lateral-g as they are willing to bend over backwards for their customers.
The ATS headers are very nice but are cost prohibitive to my project.
