people run cutouts all the time, havent heard of too many backpressure problems. i have lt's and true duals, and theyre as free flowing as a cutout and i dont have any problems

i have FLP long tubes, NO CATS, and my numbers went from 380rwhp 360rwtq (closed)
to 400rwhp and 375rwtq (open) it was hard to beleive because it reals faster with it closed.... its DAMN loud when open!!!.... sounds AWSOME at low speed and idle....

i believe there is a loss of tourqe below 2500 RPMs with the cut-out open...but once you get up in the higher RPMs the gas flows much better so it can tac out and accelerate easier... I could be totally off on this but this is what i've heard...

The only issue I had was listening to the noise which sucked. I didnt like how the car sounded with the cutout open. With stock manifolds it will not be so bad.
