Well, there's no better choice than mandrel bent dual pipes. Are you going 2" or 2.25" piping? I don't know how well side-exit will work, but it'd sure look sweet.
BTW, no cats on your new exhaust plan? It'd help quiet the noise (not to mention clean the air). summitracing.com has good prices on high flow cats.
FWIW, that's my lame critique!
