Which got me wondering, how does straight pipe size affect engine performance in a turbo'd diesel? I've heard different theories, but figured some of you guys would know the facts.

This guy evidently thinks his Dodge looks real mean this way, but he's got enough pipe for 1000 cubic inches. Wondering if he's trying to compensate for other things which might be smaller than average.

why would an inline 6 need dual stacks?.....and that guy probably doesn't know what a rain cap even is.

The redneck hillbilly stacks have been showing up around here for at least 5+ years. 
We got a local kid running around Minot that has dual 8" on his Chevy 1500 pickup. I have been quite tempted to go and drop a few kids size bowling balls down them when its in a parking lot some day.
So given the pipe size to engine displacement ratio I calculated that the 549 V8 in my old fire truck will need the culverts from my driveway for me to be cool!

I think they're ridiculous, but oh well, not mine. But I have a question. How do you install those. I mean you would have to make holes in the truck bed, no?
Or, are the pipes skinny or flattened to run up the gap between the cab and the box, and then get made large like that after they rise above the top edge of the bed's box? I've never seen a setup like that from up close in person, just from passing by on the road.

I personally think they look goofy. The guys that usually run them run chips and like to see them smoke. Gives the EPA and other tree huggers reason to push for tighter emissions. Eason
