flowmasters don't break in. there is no packing in them so there is nothing really that will ever change. what motor is it?

Take it off...

a new glasspack would make it louder

high-flow cat made my flowmaster 50 series roar

On my 22re, I initially put a 50 series on and it almost sounded like a diesel tractor because there was no resonator after the muffler. I chopped it off and put the 40 series on and it worked, but I don't like for people to hear me coming. Nice deep low sound, but not obnoxicious.

Try putting a resonator on after the muffler...?

smaller pipes and a different muffler. OR just remove the cat..

I put dual flowmasters on my chevy and thought the same way as you. Not loud enough...I'm now looking at "Race Mufflers". Dynomax...(I think) makes one called bullets. There mufflers only reduce the sound by 3-4 decibles. Just FYI. Heres the LINK

change the dual to a single pipe or dual small pipes, she will be loud!!!

If i did that I would be sacrificing power wouldn't I?
