I love my 5 inch stacks they sound so good !! I started with dual 4inch and then switched to dual 5's and the tone went down to a nice rumble!! LOL love it!
my splitter is under the truck, at the end of the transfer case skid plate. the pipes then go across the truck, to a 90º elbow up outside the frame, to another 90 pointed back. at the front of the bed, there is another 90 going up into a 3-4 adapter through the bed, and the 4 inch stacks go into the adapters.
in this rendition, the stacks are clampet to brackets on the headache rack. originally, they were bolted to the front of the bed. but that setup was a PITA to get to the nuts to put the pipes on though.
