What u need?

 

KuNtRy BoY: well ive been lookin into it for a lil while now but i cant exactly figure out whats the best way to mount the stack. i just want a single cuz i have a duramax and theres alot of bs under there that i dont feel like messin with. ok should i use flex pipe and just connect the stack with clamps or should i put the up pipe just sitting inside of the stack to allow movement between the cab and bed, or should i just weld it all together and just saddle mount it an be done???? i do everything myself i just dont know which one is the correct or best way? please help.

 

I have a welded up pipe, clamped to my Y-pipe inside the bed and then clamps bolted to bedsides for the stacks. I clamped after my up pipe so its got some flex. I didnt use any flex pipe, and I did it all myself.
