Guys I am having this rattle sound coming from my underbody whenever I was in Drive while idling, things are normal when my car is moving, it happens when I come to red lights, it doesn't make noise when I put in Park or Neutral, at begginning sounds just like heavy exhaust notes, but that was few days ago, now just this rattle, I posted video below if somebody can tell me wasupening with it thanks!

06, 6 speed paddle shifter

 

It might just be the heat shield on the exhaust.

 

sounds like the heat shield to me. try killing the car. then shaking the exhaust tips(when cold). That's how I found mine.

 

thanks guys, I ll check it out.

 

Same, the heat shield on my cat rusted out and then started chattering. Eventually it actually started dragging on the ground one day while driving. Check it out before it falls off!

 

guys think this would do? I want to try to get it fixed miself,

 

ditto on heat shield rattle. just ripped mine off today.

 

Get your sweeeet dremel and cut the lil welds on this damn shield and rip it off !! if your feel like working even more rip em' all off. The area they protects wont prevent the non protected areas, the non protected parts that might wear/rust faster ''little bit'' will require the whole section to be replaced, yes even the part that is ''protected'' lol.. its connected to it m8. The first one i'd rip off is the cat shield, that way you'll know whats what.

BTW: I laugh my azz off with the '' Blawwwblwawawaaa'' part you did slowmoooo LOLLL

 

My heat shield just fell and was dragging for a bit till I got home. Gotta use some hose clamps to get it back up in the morning.
