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.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2018/MC-10178803-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2018/MC-10178803-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10178803","components":[{"id":"engine","name":"Engine","parent":null},{"id":"equipment","name":"Equipment and accessories","parent":null},{"id":"exhaust-emissions","name":"Exhaust and emissions","parent":null},{"id":"exhaust-pipe","name":"Exhaust manifold, pipes and muffler","parent":"exhaust-emissions"}],"codes":[],"topics":[],"vehicles":[{"make":"POLARIS","model":"SLINGSHOT","year_from":2015,"year_to":2018,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
