I wanted to throw this out there for anyone considering the eastern catalytic converter. I bought and installed a couple months ago and it did get rid of my check engine light! Great news! Shortly after though, I started to get a rattle under the Jeep. It starts as soon as I start up the Jeep and doesn’t go away throughout all gears. I re tightens all of the bolts on the two main cats, but still rattles. I had my buddy get under with heat gloves and with a very small amount of pressure it goes away, at least at idle and when pressing the gas in neutral. The Jeep runs fine, but I thought I would throw out a warning and see if anyone has had similar issues with this brand? Also if anyone has had any luck making it go away. I thought about adding an additional hanger closer to the passenger side bend to see if that helps. Any help or input would be appreciated.
