There was a rumor not to long ago about Road Atlanta's days being numbered but it kinda died down, but I assure you it will come up again. The positive thing is that Don Panoz still owns the majority of land out here so no one can get it and try to rezone and restrict our track until it's non existant.
Chris-
Is this what you're referring to?

It looks like this may be the whole system that would just attach with a set of clamps.

It amazes me that "greedy developers" will build on that land (and people will buy it) knowing damn well that it is in the backyard of a racetrack and then after moving in claim that the noise is intolerable and must be stopped. It's the same BS we kept hearing on the news in Vegas while I lived out there about the community that in the flight path of the airport trying to get the planes diverted so the noise didn't affect their "quality of living". WHY THE F DID YOU BUY THERE IN THE FIRST PLACE KNOWING THE DAMN PLANES FLY OVERHEAD!!!!!

I have an issue with my 928 running Magnaflows and and a dual 2 1/2 inch...so far I just know where the monitor is and short shift through that area....but it's not a good fix. This year several of the places that I autocross will also have requirements.
Has anyone tried these inverted cones ? http://store.summitracing.com/egnsea...1&autoview=sku
They would be easy to insert at the tip and then remove.

I shoot sporting clays as a hobby and this is the same issue we have had with the gun clubs around Dallas. The legislature passed a law grandfathering the existing clubs so the the local municipalities could not shut them down because of housing developers moving in. However the developers have found it is just easier to buy the places and just shut them down than to fight in court. It is land values that are really going to be the problem.

On my 944 spec car I just run a stock muffler. I have noticed no power differences between that and various other car's set-ups. For 944 NA DE car I would suggest a stock muffler. I run it without a cat and I believe that makes a power difference, but it only very slightly increases the sound levels. That said I have never run the car at a noise restricted track so I can't say where I am on the dB scale. I would suspect only slightly lowerer than a stock street car.

This is what i have with a short piece of exhaust tubing welded to it. I can't tell if the one you link to allows for plates to be removed/added.

If you go with the Supertrapp disks, you might want to consider using the 5" disk model instead of the 4" model in the link. The 5" will flow better than the 4" one.
