Catalytic Converter As Part of Exhaust Collector
Catalytic Converter As Part of Exhaust Collector
(OP)
Hello,
It would seem that if the converter is minimally restrictive that it could be incorporated into the tuned length of the collector.
The second thought would be what proportion of restriction would require a change in the collector length?
Could the converter be created in similar fashion to straight through mufflers coordinated to work along the length of the header?
Thanks,
Jason

Not that you couldn't do something interesting with them, but the results may not be what you expect.

The main problem I see with the idea of putting it in a header is that the substrate requires shock and vibe insulation that takes up some of the available space, and also is easiest to do with a two-half welded assembly. That can just be a bolt on thing, rather than incorporating it.
The back pressure associated with it would have to go into the calculations for tuned length, and there may be some reflection at the interface, but honestly, I don't think many header manufacturers care much about actual performance, as long as it's better than stock (which isn't always the case). As long as people buy it, they'll sell it. I'm sure there's a few exceptions.

I know I would.
RE: Catalytic Converter As Part of Exhaust Collector
also I think tha ta high flow metal substrate cat in the pipe after the headers (midpipe?) would be more effective and have longer life.
RE: Catalytic Converter As Part of Exhaust Collector
I agree putting them after the headers would be better, except I don't think they would be close enough to the "stock" location for the inspectors. I also think they may have lost enough heat at that point to not be effective enough (purely speculation).
At any rate Mercedes Benz has the ability to put 700+ lb-ft of torque through their exhaust system. They must have some sort of solution that has some applications outside their programs...
