[Tom and Marj Green]

when I went to buy the Flowmaster dual cat-back exhaust system for my 2006 GT Turbo, the exhaust shop said Flowmaster makes good power but on the PT Cruiser is very noisy for the street. he recommended Magnaflow, which he said made equal power, but had a softer rumble for the street. I want both more power, along with a richer sound. anyone have experience with one or both of these, and what is your evaluation about the noise - yes, I know we all have our own acceptance level, but would like to hear what you have to say. many thanks, Tom Green, Los Altos Hills, CA
another thought - have any of you in California replaced the catalytic converter with a free-flow cat? your thoughts? they have them that meet California regulations. thanks again
