Default Stock catback

How loud would my truck be with a set of headers and catless Y with a stock catback. Wanting to put a 6.0 with headers and Y on it but not wanting anything loud. Actually wouldn't want it much louder than stock.

I'm running a 5.3 with factory y and no cats and stock cat back. A little louder at idle i noticed and maybe a bit louder at cruise but you cant hear it over road noise so i would say it wont be much louder.

Thanks. I am wanting to get a set of headers and will probably go with the pacesetters but didn't know how loud it would be with a catless Y. Gonna add 6.0 later so not wanting anything real loud.
