With my mods below, future forged 347ci going in, possible aftermarket heads. Would a single cutout at the I pipe or possibily dual cutouts after the headers be any useful power wise?

Sound wise would sound sick, but I wouldn't do it for that reason alone.

dual cutouts at the headers will not help your torque. put a single one further down

I have heard you can pick up anywhere from 3-4 hp

as prviously stated 2 right after the headers will just make u loose hp. put 1 at the i pipe not only gain hp but it will sound sick as hell

any reasons why people put them on the i-pipe and others put them by the axle? which is better? I was plannin on puttin one in the i pipe with a turndown, . . any suggestions??

If you put it as far back as possible (right before the rear end), it will minimize the cabin noise while it's open.

Yeah just throw a single in the I pipe.
