See my previous posts about removing the cat. Doing so increases emissions, and adds no performance (and may even hinder it). Just because you can't see the extra pollution doesn't mean it isn't there, and backpressure is part of the overall exhaust tuning. The only reason to remove the cat is due to malfunction...and then, only to replace it. If someone has a dyno test that demonstrates a measureable improvement in performance by increasing pollutants, I'd like to see it. If you want to pollute more, that is your choice. I just don't think there's a point. Gus Schlachter VIN #4695 Austin, TX On Sep 21, 2005, at 3:12 PM, Qume Fox wrote: > Your not alone.
