Quick question. I have the Varex full system and car is blown and cammed. How much louder will the car be if I remove the centre muffler. Ideally I want a louder idle, much louder.

I do have Varex mufflers and thinking if I want the car quiet, I can simply close the valves (which I never do now). Will that quieten it down if I choose to?

Any advice or feedback?
