Competition 12 V Head Flow Bench Numbers

Competition PA boys....pulling at Smithton Hole?

Getting some parts together to build a stack for my truck, and need to ask you guys with a stack what I should do. When tying into the existing exhaust, should I use a standard 90* radius, or should I use flex hose to allow the exhaust to flex between the body and exhaust?:confused:
 
Whats up bud? What kind of set up were you going to do? You dont have to use flex on a stack but I would. It lets water drain out, allows for movement a little, and usually makes it easier in some cases. The only dowside is that you cant make tight bends..... btw i have a single stack kit I would sell if you are interested?
 
I was planning on a single 5-6" in the pass. corner. Basically all I need is a 90 off my current exhaust and the stack. I'm going to get some 6" box and make the S pipe myself, basically a 4" sleeve through the bottom of the bed and a 5-6" sleeve sticking up. I plan on painting the stack black or gray, so I was planning on just miter cutting some exhaust pipe for the stack. But let me know what you got, would be a good reason to finally get together and drink some beers:-laf
