Hi

I just got my IS 350 3 days ago and when i was on the freeway driving around 70mph, my dad, who drove behind me, said my mufflers were shaking very hard. Is that normal or abnormal? How can I fix it? Thx

Also can anyone point me a direction in where to buy different kinds of illuminated scuff plates and installation guide? ty

 

It has been discuss before, that's normal....

 

Apparently its normal but i hate it. I'm going to see if they'll be willing to change out those stupid rubber mounts with newer ones to see if it helps. I went to the dealer and shook other IS exhausts and mine seem like its the worse... More loose than other ones.

 

ah ty ty ty
im a noob at cars haha ^^
