Default Cat Delete Pipe

So far after looking for awhile im unable to find a cat delete pipe for my 3500. All Im able to find is the muffler delete.
If anyone knows a really cheap or great price pipe please let me know.

BTW the state I live in doesnt have the emission standards.

stock exhaust? if it is just cut the cat out, measure how long of pipe you need (add 5" for the flares if i remember right) then go to any exhaust shop and they will hook you up. stock exhaust is 3.5" btw
