Greg,

I see you offer the Stromung 3" cat-back for the Spec V. I was wondering if the price on your web site also included a 22" or 24" (I forget the largest size the B15 can fit)? The reason I ask is because the picture does not show a resonator. If a resonator is not included, is there an additional cost associated with adding a resonator?

Is there also an option to add an O2 sensor bung to the exhuaust?

If adding both of these is considered special order, what is the turn around time?

The exhaust is available with resonator. Add another $85. It is 18". add a day or 2 extra. A bung is already included.
