Probably not too many, maybe 5rwhp. GMHTP gained something like 2rwhp with the B&B and I doubt the LM flows much better.

Question

Didn't GM High Tech get 2HP with the B&B compared to an SS system? If I remember they said that it should do close to 10 RWHP on a Z28...

My cutout added 6 rwhp "over" my 3in american thunder cat back. So im guessing a cutout adds 10-15hp over a stock application...

It was actually a T/A but I don't remember if it was a WS6 or not.

I believe it was a WS6, and they gained between 1-2 hp. That is why I went with an SS exhaust. It was free, and the gains would be better then my stock one. When I go to the track I hope to have my cut-out installed. That should give the most gains at the track, while the SS exhaust is plenty good for around town driving.

I want to intall an electric cut-out, so that any time I want, I can pick up those extra Hp.
