Thanks a lot Steve /phpBB/images/smiles/icon_wink.gif But as far as I was aware, they made changes to actually make the 02's less restrictive?

I am unaware of any difference between the 01' and 02' cats. I have had experience changing the cats on other cars though and found that going from one cat to another makes little or no difference, even if it is a high performance cat. Unless obviously you are switching to a larger diameter pipe with larger diameter cats. I had a trans am in which I first switched to a high performance PFP cat and I noticed absolutely no difference. I then hollowed out the original cat and put it back on, in place of the aftermarket one. I noticed an immediate difference. This mod also dropped my 1/8 mile times by over 1 tenth. The moral of my story is, it's either cats or no cats, there is no difference in between.
