I found this old thread. I am looking at getting Hooker exhaust. I purchased the car with stock exhaust but with FlowMasters. I run 12.00 @ 112 at 21 lbs of boost.
Last night I ran the car for the first time with open exhaust. I looked down and it was at 29 lbs of boost in third. Needless to say, that was short lived. Thankfully the motor wasn't hurt. Thanks to Alky.
Anyway, what MPH gain did you see when going with the Hooker exhaust?
I am seeing a 8 psi restriction.
