I can't wait.. My Rapid cooler version 3.5 is on its way and while I'm at I will do the flapper mod.Has anyone got a turbo exhaust housing I can use to get modded, which I will replace with mine, just so I can hurry the process up.This way the car is off the road for a day not a week.I also have a battery, which is only 3 months old, that will be replaced in the process.Should be worth a carton and I will even dig out the reciept to prove it.Any help will be paid for in cartons just to help stimulate the working mans economy
