Not to get off subject, but what is this rattle you are talking about? Mine rattles whenever i let off the gas. You can't hear it at high speeds (i think just too much wind noise going on) but when im slowing in gear it rattles. Also reving up the motor with or without the clutch in, it rattles as the revs are dropping. I have a completely stock exhaust.

Sounds like your precats. Do a search and prepare to do some work or drop some coin. Start checking your oil level regularly, hopefully they haven't done any damage
