Never got to wrap this up -- it ended up being a loose bolt with the RMM, caused the mount to vibrate/shake... make sure everything is nice and tight ladies!
Hey Guys, is this the headunit at hand here? https://www.joyingauto.com/joying-high-resolution-10-1-car-gps-stereo-plug-and-play-for-honda-civic-2016-2017.html
Update: The RMM was installed without fully securing both bolts, so there was a little bit of flex in the RMM causing vibration when initiating load on the engine! Anyone experiencing similar issues PLEASE recheck your RMM Bolts! Shops make mistakes sometimes!!
Thanks Sara, I actually did not have a rattle with the CBE prior to getting a RMM and DP installed, so I am thinking it might be something in that area
You are probably going to rub at 35 offset, I would advise not going above 38 if you want to run 255+ sizing... But it will look super good at 35 ngl lol
100% agree, they had the car on the hoist and were under it while I made the noise and they weren't able to diagnose where the sound was coming from - they said it might be engine movement?
that is quite plausible, I do concur that it sounds metal on metal noise, I will have to give this a shot next week, interesting that it gets louder and more frequent the more the car is driven and the hotter everything gets (but doesn't do it at all in cold start)
So I actually did this with my mechanics, they propped the hood up and I drove it slowly forward for them to listen with their heads in the engine bay, and it still happened... but that would have been such an interesting reason! lol!
@everyone please see above for a sound demo off my phone in my driveway... as you can see, warm, on idle and forward/backward it makes a loud vibration sound...
Full catback was on before FBO install, FBO being DP, IC, HVI, TIP, RMM, I actually had them hoist the car up and I made the sound happen on the lift with then underneath it and they couldn't figure it out?
Mechanic just installed my FBO mods + 62A RMM from Hasport, and immediately after installation I am hearing this VERY annoying metal on metal vibrating noise that is happening from under the engine bay it sounds like? I had my mechanic take a look after a few hundred KMs and it still hasn't...
