It might hurt someone's ears standing next to it

Really, I've not come accross anyone saying it does so far.... My next exhaust has a muffler, but no kitty

no, it won't hurt it, just move some low-end torque up through the power band.
Now, you can hurt an engine running nothing at all, as in,( no exhaust headers or
mufflers). And I'm not sure but, I don't think it's safe it is to run straight headers
or manifolds.

I just put a 4" pipe from the turbo back, nothin' but great sound and what seems to be a lot more performance, no kitty, no muffler just a mean soundin' truck that twists heads!

Diesels really don't need a lot of back pressure and may help it.
I would highly suggest keeping either the kitty or the muffler as it may be too loud?
