It is so easy to get cat out. Take a straight edge and mark on pipe some marks with a awl. This will help in lining up to weld. Measure gap thickness of cut and weld it back with the same gap space. Do not cut pipe where heat sheild clamp goes. As this would cause a heat sheild fit problem. Cat is about 1 1/4 .. 1 1/2 inches from welds front and back. Drill hole thru cat against the inner wall of pipe. This makes it easy to get a long saw all blade in. Take a saws all and saw around the cat against the inside of the pipe wall. Once sawed , cat will come out easy. I will try to post some pics in the near future.

Or if you dont want to do this , I will sell you my fuel moto header.

Thanks for the info and offers. I would like to keep my stock headers with the cat around. You never know what a liberal government might do next, so to be safe, I will probably keep it and hang it on the wall... Thanks to all of you.

Gutting the cat on the newer pipes (small o2 sensors) can cause cross talk between the sensors. Even though they are separated by a length of pipe the cross talk happens from the negative pressure wave, the one that is heading back towards the valve. This is not such an issue with the '09 pipes with the 18mm sensors up by the heads. The 2:1:2 pipe from Fuelmoto is a great replacement pipe. I have heard soon they may also be ceramic coated.
