5.9 Magnum exhaust/intake combo help

Pista, I agree to a point. I'll just say it is amazing what some people do and make power and/or go fast. We have here a stock port cruiser, then the M1 dual would get my nod.

I'll be using the RPM on my Magnum with a mildly upgraded cam and a little converter w/3.55's on a 27 inch tire. Even the stock cam that's in the '99 Magnum now works very well.
