I have a toyota celica gt with 1.8L 1zz fe, what catalytic converter should i replace it with, and should I replace the O2 sensors while im doing so or should I use the old O2 sensors? which O2 sensors should I use the universal ones or the denso ones? or does it matter?

You could get a performance catalyc converter or just the OEM one. Myself I don't like universal catalyc converters, because sometimes there has to be a mod. done. Are your O2 sensors throwing any codes yet?? But, is really up to you. you can replace them anyways. The denso, should be good. :)
Hope this helps..
