Hey guys I have topspeed exhaust and my C pillars on each side in the back seat vibrate from the tone of my exhaust. I was wondering if any of you guys have had the same problem and what did you do about it? Any comments or suggestions please? Thanks.

 

Yes, I have an 06' sedan with a stillen catback and have noticed the same problem occasionaly. It seems to vibrate the pillar behind the front door. Not sure what causes it or what to do about it??

 

So I was thinking maybe some dynamat would fix the problem. I took my C pillar apart and checked everything out. VERY SLIM room for any type of padding to go in there so i dont think padding it will work. Any other suggestions anybody?
