Thoughts, Opinions Wanted
I kind of had the same idea with my fender well headers. Mine have a slip-on merge collector and was thinking about making a slip-on 4 tube collector to replace the merge collector this way it would give me zoomies. I may still do it even though it will probably hurt performance a little but it really doesn't matter in bracket racing anyway.
Mine is a race only car so I don't have to run muffs.
