Has anyone here put stacks on an 07 2500 5.9L crew cab 8ft bed? What the install easy? Did it make your truck louder than say a 5" MBRP turbo back systerm? Looking for a loud system with at least 6" stacks, was maybe thinking of 7" not too sure how it would look on the truck Is it the bigger the stack the louder the sound or would it be the same with any size stack?

 

I have 6in stacks on my truck. Before that was a straight pipe out the side. Yes it is louder because you have the stacks right behind the cab. With the windows down it is loud, but is not "horrible". With the windows up you can hear it, but can easly have a conversation in the truck. Conversation in the back seat is a little different though but its not mind killing by any means.

And, you earn a BA factor!
