Exhaust valve still works brilliantly. And the car is nice and quiet at idle and around town!

What type of muffler configuration will the catted version be designed around? Any chance running a center delete gets the catted version to perform similar to the catless version? That configuration would probably be too loud (louder than the catless with a center delete)?
