The C4 LT1 seems to have some wicked smog stuff bolted to each exhaust manifold on the topsides. What headers (long or short) are you guys running that is drilled and tapped for this emissions equipment, and is a direct bolt on?

Re: LT1 emmisions hook ups on headers. (BlackBeast2)
SLP Shorties also have the emmissions bung (threaded hole).
exotic Muscle long tubes have them as well. Although when you go to a long tube, you have to worry about a custom setup with cats (if you're worried about staying emmissions-legal).
