HA........some people really like that noise( and my wife is not one of them). It's now a matter of me or them!
Yes, dual exhaust with old split exhaust manifold no cross over pipe. The good news is that I'm armed and ready for battle. Vacuum gauge, flat blade screw driver, tachometer and no fear, well maybe just a little. If I make it out alive maybe I'll have answers for those that are interested. Exhaust farts be dammed full speed ahead!
Thanks, Steve
