Using aftermarket converters

[ncautoshop]

Any input on aftermarket vs oem converters. Just got bit for the first time. Wondering if anyone has any experiences. What's bad in this case is - although it was disclaimed that using aftermarket a code could reappear, I feel responsible. She asked what I would use - I said aftermarket. I've never had issues.

Secondly the converter we sold her was in the $590 range OEM is over $1,000. Only lasted about 1,000 miles.

The aftermarket carb compliant ones are fine, I had one come back on a 1.8l vw but I warrantied it and the 2nd one has been working for over 2 years. Before the NY law we used to weld in the $40 obdii cats which had about a 70% fail rate. But if a customer could spend $100 to pass inspection vs $1200 they didn't care if the light came back on in a month.

This is a federal emissions car with less than 1,000 miles on the cat.

We have had problems with aftermarket converters. We prefer to go OE.

We only use factory converters now. In the past we had nothing but problems with aftermarket and OEM converters.

being in NY. I find after market cats manufactures are not offering ny or cali compliant cats for a lot of vehicles so I don't like taking a chances.

Forgot to update - napa replaced the cat. No repeat failures.

Best thing to dois price the customer for the BEST qualitycat you canfind aka oem. Ifthey don'tlike the price, then allowthem to get they're own cat and offer no warranty. Don't let the customers wallet dictate your parts that your shop warranties.

Not all weld in obd II cats are the same. Normally your parts supplier can look up the proper sized universal cat. I don't do a lot of these, but I have never had a propey sized obd II fail, but I have seen plenty of wrong sized cats fail after a year or two
