RE: Removing Catalytic Converters

[glen powell <gpowell@acacianet.com>]

I don't have HP numbers but I do have very accurate 1/4 mile times.

Example: 85 ur-q, with then stock K26, K&N, 2 1/2" open exhaust, IA Stage II, stock cam,
with cat and with 2 1/2" test pipe = ZERO difference in ET and trap speed. Measured at
New England Dragway, NH, on two different nights, not exact same ambient weather
conditions, but pretty close. I expect that there will be a difference when I test again with
the new KUQEFH.

Can anyone provide accurate (ie tested) figures for bhp increases resulting from removing catalytic converters from engines such as 280bhp 4.2 V8 or 230bhp 2.2 turbo?
