Spot-weld locations securing the outer shell portion have been changed to improve overall rigidity. A gap may develop at the spot welded seam as a result of repeated thermal shock (heating / cooling) which occurs during normal use. The gap does not create an exhaust leak. In some cases, a rattling sound from the muffler may develop.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2016/MC-10111070-9999.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2016/MC-10111070-0001.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10111070","components":[{"id":"engine","name":"Engine","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":"SUBARU","model":"LEGACY","year_from":2015,"year_to":2017,"match":"exact","vehicle_ids":["2015_subaru_legacy","2016_subaru_legacy","2017_subaru_legacy"]},{"make":"SUBARU","model":"OUTBACK","year_from":2015,"year_to":2017,"match":"exact","vehicle_ids":["2015_subaru_outback","2016_subaru_outback","2017_subaru_outback"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
