hmmm, well id agree with everyone above, check the intake pipeing, IC pipeing if its turbo'd. also check all vacume hoses. a lacking muffler wouldnt cause it to drop the rpms hell alot of us are running with no cats and 3 inch pipeing and have no problems at all. if the muffler is plugged i doubt it would cause that kind of problem, if thats the case just chop it off. and put an exhaust tip on it. its not missfireing at all? any codes? <<< you need to put a paper clip or wire or somthing inbetween termainals T and E1 of your diagnostics box in your engine compartment... does it have the stock Bypass valve?
