I bought a couple of pieces of it from Orielly's and stuck them together. All you got to do is push them together and either clamp or weld around them. It did not take very much of it as I did not run my exhaust all the way out the back. I am running an LC Engineering Header it comes all the way back to about 1/3 of the way down the transmission. I stuck on two sticks of pipe and a Dyno Max muffler. I do not run a cat' on mine just a muffler and a resonated tip to take a little bit of the edge off the exhaust note.
