Just thought I would post in here for anyone that was curious. I helped my cousin install a set of the M2 Headers from ebay that runs around $110 shipped. I can honestly say I was more than impressed with them. Fitment was great and the welds looked very nice. They came with nice gaskets, we did use the factory exhaust manifold to head studs over the bolts they offered. The headers did change the exhaust note some on his Flowmaster Force II catback. He said he also noticed a slightly increase in fuel mileage with the headers too.
