Would you see that much of a benifit with a cut out and nitrous? I have a series 3 muffler, LTs, and a good ole nitrous cam.

 

yup, sounds like a good route to me

 

Well to give you an idea ti what I'm running. Stock manifolds( I'm cheap waiting to get a good set used then just recoat them same as new but cheaper) ORP, 4in catback with a magnaflow muffler and one spintech in line. With a 200 shot my car was dyno tuned to 457rwhp and 588 rwtq. With the i-pipe unbolted (same as cutout ) I made alittle more hp but less tq
