Q300/Slight rattling sound on cold startup
Hey guys I'm wondering if anyone can help me out with this. I started to notice that at a cold startup I hear my exhaust rattling a bit.. When I apply slight downward pressure on the left exhaust tip the rattle disappears.. The moment I release it starts up again. Only last for about 20 secs and then its gone. Any suggestions? Could it be my hangers (stock)?

Mine does a similar thing... has done it since day one. Once its warmed itself up for about a minute its gone so I stopped worrying about it. I chalked it up to cold start resonance in the metal that changes once its expanded. Who knows. I do love my setup though.
