No Exhaust, Please respond

[Harlee&Tahoe]

Will I damage my motor if I drive around with no exhaust hooked up?
I tore off from muffler back (hollow) cat still there. Will having no backpressure promote engine damage or piston slap. I need to drive over mountain passes
Thanx Harlee

You should be fine. Just loud, thats about it.
