Guess there won't be a before and after dyno... I'm still a bit skeptical of "shorty" headers.
What are the diameters on the primaries of the momentum headers vs OEM? Is the merge collector nicely polished?
Either way, wrap looks fine, and good luck!
EDIT: The collector interior looks a bit rough on the inside to me, but if the primaries are overall wider, especially with VVL tuning, it should make some decent gains.
