Im having the hardest time trying to find so 4" pipe to remove my cat and muffler. Every shop I have been to so far tells me they cant work with anything larger than 3" cause thats as big as their machines go. Does anyone in the north east side of Houston know of a place that has 4" pipe and can expand it for me? And does anyone know of a place online to order 4" or 5" mandrel U-bends from?

A straight, 8 foot long, piece of 4" pipe will span the length from the clamp in front of the cat to the clamp behind the muffler. No bends needed. I just need the raw pipe with one end expanded to slip fit and a 12" long piece with both ends expanded to connect the other end.

Im not going to buy a premade part when straight pipe will work just as good. Im gonna do stacks once I get all the parts gathered up so Im not gonna buy another exhaust system first.

I found a site..

..But my computer got sick and I have lost the bookmark. I am looking for it again right now. They had everything, different size bends, lengths, and sizes.

I know its not the best info but you can also google it, that is what I am doing.

Hmm. I hadn't thought about just going to an auto parts store. I will check out NAPA this afternoon and see.

I know what you mean about the computer man.

I have heard, but have not checked it out yet, that you can get 4" exhaust pipe in various bends at a big rig shop.

...will sell you the whole 5" exhaust and maybe the strainght sticks but will not sell the tail pipe and over the axle bends. I asked him and he told me he only sells the kits.

Still looking for the web site

Try Dynaflex Chrome Muffler Stacks | Chrome Stacks | Rubber Intake Elbows | Donaldson Mufflers for components. If you've got some fab skills you can buy the pieces and make your own kit.
I had Pinnacle Power (Jardines) in Wyoming bend me a muffler delete for factory muffler. They were cheaper than RPM Outlet and Genos. No clamps or hangers but the pipe was perfect. And I wasn't a number. I was Mr. Lewis when I ordered and when I called to get the tracking number for shipping. Good folks.
