if you add the xpipe it will be mildly louder.
It really depends how loud you want the exhaust to be. I know if you just throw straight pipes it will be really loud but i think their have been issues with rattles and maybe a loss of power. An x-pipe wont be as loud but still give you more sound than stock.
If It was my truck i would do the xpipe and see how i liked it. The pipe is like $80 and install around $60-80 . Good Luck
