where should i put my cut out(s) .... one right after the y pipe or 2 after the headers before the ypipe meets?
any suggestions... stories...anything

yes and yes. if you want 2 they go in the y pipe after the headers, one on each side.
if you want one, goes in at the end of the y pipe after it connects from 2 to 1.
im getting dual electronic DMH cut-outs with flow-techs. good price on their site. only heard good things.

well yeah see i want to know is there a good gain other than more noise for the 2 cut outs vs the 1 cut out, or is it a waste of money and im leaning towards 2 cut outs tho

You'll likely note a modest gain on a dyno depending on your application. On a bone stock LS1 with the stock catback, you might see 10 - 12 rwhp, however if you already have a better flowing catback and aren't running a H/C/I, N2O or forced induction setup, you'll likely only see a nominal gain.
Aside from a slight performance gain, I LOVE my cutout mainly because of the sound. I went with an electric cutout and I usually keep it around 50 - 60% open -- just enough to add a little volume to the exhause note and keeping it only parly open helps cut down on the rasp a bit.2002 Camaro SS M6, 2.5 PRC 5.3L heads, TFS 228/230 cam, FAST 92, bolt ons + a 10 lb bottle in the back.

Yeah man i'd just go with one in the i-pipe. I can't feel gains but i know they are there for sure. As far as sound goes my buddy had the same mods and two cutouts instead of one and we sounded the exact same.2001 SS M6 black
