Will a Cutout give a stock SS any gains? Anybody tried it?

There's got to be about 5 billion threads on this. Search my friend....it's a wonderful tool. A cutout will gain you 5-8 upper rpm horsepower on a stock ls1.

Yup, you might gain 5-10 rwhp. I would say go for it. This is one of the cheapest mods you can do. I have tried a cutout in the I-pipe and also the "Zed" style just before the muffler. I have the cutout in the I-pipe now, but prefer the "Zed" location. The horsepower gains of the two locations are probably similar, and installing it just before the muffler lessens the interior resonation.
