Message	I run the 5 bolt SZ 3" stainless expansion DP's. I doubt that a 4" Downpipe would be better than SZ's current 3" Expansion downpipes.... They are engineered and designed for maximum performance on our Zs. Would this "custom" 4" DP be just a straight shot single pipe? Thats where the expansion style 3" trumps by separating the wastegate portion and the turbine portion maximizing efficiency and decrease LAG! Even if you had the 4" DP's I doubt itd make much of a difference even at the 6-700whp level unless the whole exhaust was custom made and 4" turbo back... which I think would be overkill and not much of a HP difference for the effort involved! src="http://i47.photobucket.com/albums/f192/drk93tt/Picture6.p ng">
