I'd like to design a nice system. So far I have two designs, and need help picking one:

1) Stahl headers (1 3/4") dumping into a glass-packed free-flow (thru-flow) muffler, which takes an immediate 90* turn, and dumps out of a resonator tip in front of the rear wheel.

2)twin pipes (1 3/8") coming out of the stock manifold, dumping into seperate Supertrapp adapter tips, just behind the front wheels.

I have the Stahl, but pipe-size wise,it's more restrictive, so I feel I could pass more air thru the stock manifold, down-pipes! What do you think? Josh
