Just got my cutout installed and it sounds awesome but it causes alot of vibration any long time problems from the vibration or just one of those it just shakes you silly sort of deals.

 

I’ve driven around with my cutout uncapped for about a year since the cutout was installed, there hasn't been anything that has broke because of it I don't think? The only serious problem I had with the car was the heater core blew about 4 months ago, but I don't think I would contribute that to the vibrations from the cutout. It does get annoying from time to time trying to talk on the cell phone in my car though

 

Just a bunch of squeaks and rattles.

 

Yeah, I've had a cutout installed and uncapped for about 2 months and noticed the same thing. Don't worry about it. The whole car vibrates.
