Update from my 11/2/17 review. Again you be the judge! Since my visit to Ken's where I was told I needed a catalytic converter for $900., I have driven over 5,000 mi. with no issues. On December 28, 2017, went for a State emissions test for renewal of my registration and PASSED! On January 4, 2018, took my vehicle in for an oil change and asked while they had it if they would check my engine on their analyzer. When I picked up my vehicle, they said they could find no issues with the analyzer. Why do I need a CATALYTIC CONVERTER for $900.00? I just don't understand!
