Does anyone have a set of original exhaust manifolds for the PRV laying around that I can either borrow for a while, or if need be buy outright? My last dyno runs with my new intake manifold and EFI setup tell me that any additional HP gains need to come from the exhaust system. It'll make fabricating a set of custom manifolds a lot easier and I won't have to lay up my D while I'm at it. Details on how it's done of course will be free to the list if and when I'm done. I'd like to drop the stock manifolds, cross over pipe and the cat, and go with twin 10 inch stainless steel Supertraps on custom headers. Both independently exiting the manifolds directly towards the rear of the car and terminating in the stock rear valance exhaust tip cutouts. Thanks, Jim VIN 6147
