So was riding today and all of a sudden the exhaust was extremely loud on the 2017 Z500, thought I lost a spring or two.  Not the case, inside the heat shield the exhaust pipe broken into two pieces.   Easy enough to remove, could not get the oxygen senor to come off however.    So, replace with factory exhaust or aftermarket?    First time for me that I am looking for a replacement part, machine has been great with no real issues up to this point.   Tried searching the forum for this topic and not too much came up.

[2015 Z Force 800 53/Trail EPS]

No aftermarkets so just get an OE, donuts/gaskets and I guess a new O2 sensor.

A little heat on the pipe will probably help release the O2 sensor.

Don't contaminate it with anything like penetrant.

Thanks for the feedback.

Picked up my new pipe assbly from the dealer today,  they have really beefed up the brackets with this new exhaust pipe.   Almost wonder if I could get CFMoto to reimburse me for the part as it was obviously a design fault that it broke.   Thoughts?

Mine broke under warranty was replaced with the upgraded one and it broke so just welded it . This is all under 6000km .2016 z 500

Wanted to provide an update, was extremely happy and somewhat surprised that CFMoto covered my pipe under warranty even though my machine is 4 years old   They did have me work with my local dealer to submit the claim which they were more than happy to do for me.   Great company and great dealer support!
