My recommendation is leave it alone. Removing the muffler won't change the sound or sound level and tampering with anything else will set codes and cause you to fail a real inspection.

Exhaust modifications will do nothing for performance or fuel economy.

x2 all it did for me was waste money.

I installed the "muffler delete" pipe on my '08, it made no difference whatsoever... Leave it alone x3 (until someone makes an entire emissions/computer friendly system).

The only thing you can do would be to install a different muffler, or stacks, or one of those "dual" exhaust systems. If you have emission inspections, and you want to remove the emission stuff, you're playing Russian Roulette with a Glock. Not very wise...
If you want more sound, I think you may be out of luck, since the emission equipment pretty much kills all the sound.
