ok....here is my problem. when ever i accelerate, especially b4 the engine is at operating temp, i hear a rattle of metal. the guy i bought the car from claimed that it was the heatshield on the header, but i dont think it is. i got under the car and noticed that it came from where the header pipe hits the CAT....is there a gasket or something down there? i hope its not too costly, bc right now i need to save for a timing belt replacement!
THANKS!
