don't pay $500, that is way too much.

You can buy two catco high flow cats. I think they are about $75 each.

I went to a muffler shop and they welded the new cat on the car for $30.

Do not go to the stealership.

 

Thanks for the feedback. Of course the SES goes off 24 hours later and everything seems normal. I just may go and do the O2 sensors anyway... steve c
