I've been contemplating a new exhaust setup for a while, and i really want a new sound. I have hooker shorties and y pipe, to single 3" pipes all the way back to a flowmaster 40 in the back, and a single out.

My question is:
Would i see any power gains at all going to hedman longtubes, to 2.5" x pipe, to dual moroso spiral flows dumped before the rear axle? or would it pretty much just be a more aggressive sound?

 

no, you are perfect where you are at, that is overkill for your 200hp 305.

 

i know its overkill, but im kind of going for sound now. im tired of the flowmaster sound, and id like to go a little louder as well.
any power gained at all would be a plus.
