Hey I have a 91 chevy caprice. I makes some kind of rattling noise whenever I accelerate. It does it around 10 minutes after I start the car up. I just recentley took out the catalaytic converter and the stock muffler and repleced it with straight pipe running through a flomaster. I also just recentley got my oil changed and fliuds checked and eveything and it is still making that rattling noise. Any help?

Can you pinpoint where the rattling noise is coming from ie. Exhaust or the engine or chasis.
If its a metalic rattling sound it may be a heat shield that may have gone loose and is rattling.
