Notable side-effects include, faster than before jump to the shift light indicator, and a meaner exhaust note at idle.

^ That's interesting, something I'd wanted to try too. The cat-con I guess is in the root of the 'Y' splitter pipe section. Another guess: its an interference fit so removal is the hard way - hammering. The honeycomb can probably be drilled out easily but the sleeve would need an arbor and a mallet.
Nice to know about the reduced heat build-up. Seems relevant though as the gas flows out freer now. Wonder if the drastically reduced back-pressure is accommodated well within the envelope of the ECU. The lambda readings would be quite different without the cat-con.
The frame heating is the result of direct heat transfer from the engine body so I don't think it will be any different with/without the cat-con.
And now that it (the cat-con) is out for good
, will sure like to give the un-constipated '1 a try when we get there on the trip.
Keep us posted on anything unusual post c-c removal.
