I went 9.49 on some tti 2 1/8 and 3"pipes w/two chamber flowmasters.
I bet it'd be close to two tenths quicker w/ something less restrictive though.
A pro stocker would probably run 7s w/ some Super Turbos on it. Does that mean super turbos are gonna work good for a 9 sec car since they went 7s on something real fast? They're still horribly restrictive.
normally I run the 3.5 pipes w/bullets., I put these on for something else(can't remember what tho.)but decided to make a pass and was surprise at the et can't remember the mph.
