So I installed Eibach several months back..and so far awesome...I have noticed that the rear tailpipes kind of vibrate going over bumps and such..only at lower speeds. Kind of intrusive into the cabin...anyone with springs have this? I'm pretty sure it's the tailpipe as i looked under that and gave the exhaust pipe a tap and seemed like the same sound.

 

I think I have this problem too, I hear a metal rattling sound whenever I close my trunk or sub hits. Definitely coming from the left tail pipe area. I can't replicate the sound by hitting the exhaust, and I can't get it to stop by holding my hand on the metal there. I didn't notice it before the Eibach's so maybe you're right it is related to that installation.

 

i also get this but only when my subs hit

 

glad to know im not the only one....ill be at my friends shop next week..ill have him take a look...

 

Hasn't happened to me and I always have my music on Max Volume. Def get that checked out.

 

btw i wasnt talking about the two subs in the back seat. i got 2 12's in my trunk
