has anyone ever put a cam in with the stock muffler on... like trying to be a sleeper kinda sort?? i know this is stupid but just curious

 

one of my exhaust systems is a 3" DMH e-cutout and stock muffler. There is no hiding my cam, lol. but it's still pretty quite. It's a raspy with no cats though. Seems to have a lot more tourqe, just a little slugish on top end.

I think I'm going to do a couple pulls on dyno when it cools off some. I just wanted to see the difference at the wheels
