I've said it before and I will say it again, if you drive it on the street leave the catalyst in it. Unless you drive the car in the top 10% of the rev range all the time, you will see no benefit. If you do drive it in the top 10% you will see very little benefit. Regardless, all of the driving done without a catalyst will result in unacceptable amounts of emissions. Its on there for a reason and that reason is not to rob you of gobs of power.
