Mufflers, Which Flowmaster? Options

[Randal]

II'm getting busted for loud exhaust at Alameda where we have to be quieter.

I currently have a delta force flow master (single chamber) welded on to the extension pipe to my header. This muffler is small (3" high by 7 or 8" case).

Performance wise it works. You can't tell any difference from running an open exhaust; nice but loud.

Here are the alternatives.

If any of you have experience please post your experience.

Flowmaster 40 series - two chambers (4" high - 13" case). Single input, single output

Would you say this produces 95 db or less? Any feeling for power loss as compared to an open pipe.

They also offer a single input, dual output, which looks pretty cool, but (my guess) is probably noisier.

Flowmaster 50 series - three chambers (4" high - 17" case)

Would you say this produces 95 db or less? Any feeling for power loss as compared to an open pipe.

Flowmaster's are pretty nice as you can get 2.25 pipe inputs on any of the above. I think that all of the above will fit without sticking out of the back of the car, one just has to be a bit creative with the installation.

Thanks.

I have (2) 40 series mufflers on my v8 car (one for each bank) and really feel they are to loud for the street. But my exhaust is really short. I would say it's under 95 decibles but it's louder in the car then out of it (it seems). I have no idea how they would behave on a 4 cyl. 914 My friend has a flowmaster on his 91 integra and i think it's the 50 series b/c it's not very loud and gives a nice tone to the exhaust. I would go with the 50 series.
