THE LOWER (REAR-SIDE) OF THE PRE-SILENCER MAY BE THERMALLY DEFORMED DUE TO INSUFFICIENT RIGIDITY (FEWER WELD SPOTS). THE DEFORMED PORTION MAY RESONATE EXHAUST GAS PULSATIONS, WHICH CAUSES NOISE. A REINFORCED PLATE HAS BEEN ADDED TO THE PRE-SILENCER TO INCREASE THE RIGIDITY, THEREBY ELIMINATING DEFORMATION.","document":null,"url":"https://open.wenmarpro.com/bulletins/10105647","components":[{"id":"equipment","name":"Equipment and accessories","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"MAZDA","model":"CX-9","year_from":2010,"year_to":2015,"match":"exact","vehicle_ids":["2010_mazda_cx-9","2011_mazda_cx-9","2012_mazda_cx-9","2013_mazda_cx-9","2014_mazda_cx-9","2015_mazda_cx-9"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
