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.
