I just did some testing today. My 964 3.6 L engine has Rothsport headers at the GT three muffler. It’s 75 miles an hour in cruise at fifth gear at about 3000 RPM. The car is 86 dB in the cabin. That’s loud, too loud for a street car, and that is on the quiet side of the mufflers.

Thanks again for the inputs.

I think I will go with the premuffler and exhaust. Maybe the active exhaust version.

Appreciate you all.

Any updates on your decision or final product?
