My question is about the Sports Exhaust option. To some this might be a dumb question , but anyway....

I plan to get the sports exhaust option on a C4S. I know you can turn the sports "sound" on and off from inside the vehicle. I plan to put on aftermaket tips. So, where does the "sound" originate from? If they come from the tips, and by adding the tips, will I be able to turn it on and off still, or will the new tips result in hearing the exhaust constantly?
Do you know what I'm trying to say? I want to add aftermarket tips and still be able to turn the "sound" on and off.
