High Performance Cat

I'd opine that to get the hp that they achieve in the kompressor models, that the cat that came from the factory would be considered a "free flow" cat.

Call Ed at Ed Hansons Muffler Service in San Diego to back this up.

Cat removal

Guys trying to avoid the big-time federal fine associated with removal of a major polution device call the free flow cat a 'test pipe'. Every dyno study I've seen indicates no appreciable increase in power. Occationally If the ceramic element is cracked and causes an obstruction but the temperature goes up and your dash light comes on, or you hear cracked ceramic rattling around. I've always wondered why those determined but unconvinced individuals do not simply remove the ceramic element which holds the active chemicals?

"test pipe"

There are, actually, high performance catalytic convertors available. The ceramic element converters, as used on MB products, do not cause an appreciable restriction. There is a company which clung to the pellet bed style converter for many years (GM) and actual performance gains could be made by changing these to a creamic element style. The enlightened, MB (or DC as they now like to be called) included, have used the ceramic element style for many years, and I'd be surprised if a "hi perf." cat would cause an appreciable difference on a car that is more than likely optomized from the factory. There is a possibility that some gains could be achieved by changing mufflers.
