“Improper Muffler”

Hi everyone

i got a ticket for improper muffler/too loud S75 (1) last year and took it to court and my date is coming up soon.

i have never been to court either so any tips there would be nice too.

i have changed my cat-back exhaust on the car to this one:

its a magnaflow muffler and i also even added a resonator on it. so its got a catalytic converter, resonator and muffler and still got a ticket

what can i use to help me in court? Should i print out the magnaflow page?

Thanks!

any ideas? 42 views? please
