Now i have a question for everyone:

what is your fuel economy of the of you with a catalytic converter and those of you who have removed it??????

I got 40 mpg with my car before the BP swap, and that was with cats. And before i did the swap I did full exhaust to it, no cats and a turbo cheapy muffler, and I got a couple mpg better.
I really didnt notice a whole ton a mpg gain, but it did run smoother and some power gain.

Thanks
Mike
