## NHTSA's summary

Polaris has identified a quality issue affecting a small number of Slingshot mufflers, where insufficient penetration of muffler plug welds weakens the muffler wall, making it susceptible to fatigue failure. The first mode of failure is a loosening of the wall, distinguishable by a rattle during normal engine operation. If left unrepaired for an extended period of time, a hole may form in the muffler wall resulting in noticeably higher noise levels.
