No long-tube headers and definitely no cam
Drivability needs to remain 100% stock-like with little to no additional noise in Tour mode (muffler baffles shut); these are my self-imposed requirements.
As of right now the C7 guys are just porting the stock intake manifold as there is nothing yet available in the aftermarket (or simply leaving it alone), but results have been mixed and I've seen nothing mega concrete yet in terms of gains. The C6 guys either port the stocker (totally different design), or get an aftermarket and have that ported (FAST, MSD, etc.).
