Here's my problem, whenever I'm coming out of first from a dead stop I hear this sound that sounds like metal straining/kind of rattling. It is coming from the front of my car. I just put in a new 5zigen Fireball but I don't think that's the problem. Anyone have any ideas?

 

Heat shield could be loose and rubbing/bumping exhaust.
Shift linkage could not have enough clearance and bumping exhaust.

I have it too, I am just to lazy to get under the car. 1500-2000 BUZZZZZZZ

 

heatshield..when i got my fireball..the stock heatshields rubbed it sometimes.its all good just bend that away..or have a muffler shop remove the piece thats hitting

 

heatshield... mine did the same when i put a new cat back on. it should go away if not just take the heat shield off

 

Could be throw out bearing on tranny, mines going out, and sounds rough when I leave a stoplight.
