Open down pipe ?

How loud will it be if I would just unbolt the rear part of my exhaust?

and will it mess anything up ?

Where are you wanting to remove just the tail section or from the front pipe back.

I unbolted everything after my frontpipe and it was loud. But all the diesel soot starts to build up under your truck and you can feel the exhaust, plus it felt like I lossed some low end torgue. I did gain alittle mpg too. But just get stack or a 5" exhaust if you want loud and not to loss low end torgue. IMO- O it goes downpipe, frontpipe, muffler, tailpipe

Other than the possibility of filling you cab with fumes and covering the underside with soot it wont hurt anything.

The underside will get full of soot and the cab will vibrate. It will annoy the crap out of you and kinda sound crappy from outside.
