What’s up everyone! My question is, has anyone had any experience with dented resonators. My issue is that i was driving down the road (spirited) and hit a large bump. I’m lowered on BC coilovers. Ever since then I’ve gotten a vibration/noise mostly while deaccelerating around 2.5k and 4K rpm. My exhaust does not seem any louder while accelerating other for than a short moment at 4k rpm, which made me think i had a leak. I lifted the car up and triple checked for leaks in the exhaust and nothing. I checked the brackets which were all good and also looked to see if the exhaust could be touching something to make the noise but no luck there either. My resonator has a pretty large dent in it about the size of a golf ball. I’m just wondering can a resonator make this happen? I’ve looked online and they say sometimes if a baffle breaks inside the resonator it may make noise. Just was curious if any of the people on this forum have had or seen a issue like that.

Thanks I’m advance !
