Clean, simple, does the job.
They do as advertised. The best part is, they have a hex head so you can torque them properly. The pictures show them as being round but the set I received were hex head. Good, clean stainless steel.

didnt use
The exhaust system suggested to buy these, but we're already included with the exhaust. Although I am sure they work fine it's a plug.

Needed for 16 Fatboy for Reinhart 2-to-1 exhaust
This should have been included with the exhaust system and not a separate purchase.

When I put what kind of motorcycle I had, it should have triggered or someone should have called that I needed the adapter. My mechanic told me there was a problem and had to contact RevZilla to find out there is an adapter that had to be purchased separately. for the price of the exhaust system, they should include this in every box so there is no questions of "need or not"

Poor poor having to purchase an adapter that should have been included

My o2 sensors are too small for my short shots, this will allow me to use my sensors with the short shots.

Can i use it on my 2015 883 the exhaust I have the o2 port is too big for the small o2 sensors?
A C on Jan 13, 2016
BEST ANSWER: This is the solution to your issue; there are typically two different sizes and this is the typical adapter. Don't over torque and strip the exhaust theads.
I bought V&H Short shots, the o2 sensor port on the Short shots was too big for my o2 plugs on my 2014 HD Iron 833. Would these be a solution for this?
Ron Q on Dec 1, 2014
BEST ANSWER: Yes...this is exactly what you yoy need and i had the exact same problem. They screw into the O2 port and then you screw the sensor in. Makr sure to use some anti sieze on the sensors before installing them
