So it would be ticket loud huh? Sounds good to me. Since the LM is straight through then no muffler would sound similiar to a LM. I cant find any clips of a stock LS1 with no muffler anywhere. I have the straigh pipe with a cat set up on my 350 pickup and its deep but since the LS1 is aluminum I know it doesnt sound like that.
As long as you bring a pipe back from the y-pipe and bring it all the way to the rear bumper with some tips, it should sound like SLP LM. My car is pretty much stock with the LM on and it is loud and sounds pretty good.

I've gone !muffler with cats on my other 2 LS1s. Sounded decent IMO. However, I like my current setup with the stock catback. It's still quiet when the cutout is closed, but pretty loud when it's open. I'm just waiting a little while before I do TDs with 1-chambers again
