Ive made up my mine that i wanna build a set of stacks but i am having trouble finding the tubing for my cross pipe. I was wanting to use 6x3 tubing but all i kinda find in my area is 4x4 and 6x2 tubing. I am gonna run 5 inch stacks so would it be ok to use the 6x2? thanks for the help guys

You could use the 6x2, but I would personally go with the 4x4, thats what I have, and I welded plates on the topside of the tube, big enought to weld 5 inch pipe onto it, for the stacks[img=500x375]http://www.pavementsucks.com/forums/attachments/200507/attachment-837111.jpg[/img][img=500x375]http://www.pavementsucks.com/forums/attachments/200507/attachment-837112.jpg[/img]
