Purchased converter and took it to a local independent muffler shop for the install. No problems so far.

I’ve had a couple converters stolen from Late model F450 V10 box trucks. This converter is the correct size and was fairly straightforward weld on installation. The reason for One Star Review.. I found out after it was fully welded on… the two removable plugs which I assumed would be to install the O2 sensor, are 1/2NPT thread pitch.. why anyone would do this boggles the mind. Most common O2 sensor thread pitch is 18mm. So keep that in mind when you order yours.

Even though the web site says it can be used in CO, it's not true. Must be original parts to be compliant. Returns subject to restocking fee, so BEWARE.
