The very first mod I did to my car was tondeill out the internal bafflesnof the muffler. Even with such a minor modification there was a drone.

I had my car straight piped for a while earlier this year. Don't do it. It's too loud. Like permanent hearing damage loud. I had to wear gun muffs while driving and it was still loud.

Interestingly, even straight piped, there's a drone. Like a crazy loud one. 2500-3000 rpm.

My conclusion here is this - there's a reason Porsche made a boat anchor of ankuffler for these cars - its the only way to cancel out the drone. The drone is inherent to the m96. I don't know what they did in the 996, but anything other than the factory muffler will reveal the drone.

Now, whether keeping the stock muffler and going with catless headers will do this also, I'm not sure. But I think that's the only possible modification that wouldn't produce the drone. Maybe someone who has done that can chime in.
