[BUIZILLA]

FWIW, I researched the hell out of this for 2 cars of mine, an L78 Camaro and my 69 Nova... on my L78 Camaro I used the Flowmaster 2.5 kit with balance pipe and crossover muffler behind the axle, dumps behind rear tires like original, GREAT setup, quiet with some nice tone, verry efficient... you'll be very happy... on the Nova I bought the same Fmaster front pipes, but used dual 2.5 stainless steel Magnaflow mufflers, an x- pipe in front, and Fmaster tail pipes over the axle exiting behind the rear tires, this sytem has a sound that must be heard to be believed at 7400 rpm with a small block.... but it's nice and quiet...
