I have an Arrow header on it's way to me... without the cat...

The problem happens when unburned fuel contacts the catalyst and then ignites. This will cause the monolith to melt and block flow. I would not suggest doing this unless you remove the catalytic converter.

I also have a Arrow pipe on it's way without a cat and will be interested to see what you come up with. That is one ugly system that has to go :)
