Re: single stack-how to?
Get yourself a 7 inch stack, 5 to 4 adapter, 4 foot flex pipe get a couple band clamps. Contact Grand Rock for the upgraded clamp that bolts to the bed, no need to weld anything, get yourself a 4 inch hole saw to drill your hole from there you run the flex pipe from inside the bed down to your exhaust cut excess flex pipe as you go till you get a good tight fit.
This is how I did my single stack a while back. Wasnt hard at all for me. Less holes in my bed the better, I'll try and take some photos of it when I get a chance.
