hi local guy.
You can get a open end air filter like Green, Cobb, or Mountune, and get some intake/by-pass valve whoosh noise when you shift.
I'd recommending picking up a dead pedal to save the carpet on the left. Boosted By Design makes a nice one, there are others available.
If you want the exhaust to sound like it should from the factory without getting too loud, and without breaking the bank, have a muffler shop do a resonator delete. I plan on doing one once I get my car.
We'll have to get together some time.
