If you only remove the 3rd CAT you'll be fine. Make sure you get a third CAT pipe with the threaded bung for the O2 sensor. Mine will be up for sale in about 8 weeks time when I fit the sports CAT.

Ok, thanks.
I just opened the third cat, removed all restrictions, and close it again!
Now i´m ready to put it on back, i just was afraid of cel light.
But like you said will be ok.
One more thing did you get any gain or just more noise?
