Kyle, not a lot of options for the 230 as far as exhausts go!
Your options amount to stock, Cobra, DG xcellerator, or a universal fit silencer like the megamax from FMF, HMF, or supertrapp.
The DG gives it a lower exhaust note, which amounts to a quieter sound...doesn't really lower the db.
Cobra makes it louder, and the megamax is adjustable.
Oh BTW, glad you got it fixed up!
One thing I can't stand is putting everything back together after not finding anything wrong...and the problem is magically fixed.
...great, so that means it could magically break itself again for no reason whatsoever
