pegged at 94.6 dB at Seca today
stock exhaust with the baffle switch disconnected. I reconnected it and had to stay just under 4k rpm in 4th to keep her quiet. That sucks coasting up to turn 6. What other options are there so I can go wot up that hill? baffle? another person with a GT3 had a 90 degree pipe on his exhaust and also got meatballed so I guess that doesn't work.
forgot to mention this was during a sunny and clear afternoon.

if you short shift to 4th gear, stay track left, you might make it at WOT if it's sunny.
how wet was it today? see you tomorrow.

why don't you guys put a direct 12v line to both vacuum valves? you can actually put a switch on that line. That will keep the exhaust quiet regardless of throttle position and RPMs. There might be a small change on the power curve at high RPM, but most likely a few Hp.
I just can't justify not driving such a great car at Laguna Seca, Lime Rock and all the other sound challenged venues.

Roaming sound check! I want to go to LS in my 997GT3 but I have the Sharwerks exhuast bypass and am worried it would be a wasted day if I can't pass the sound police. I figured if it was just turn 4 I could let off the throttle while going up the hill, but if they have a "roaming" sound station it seems like it will be futile to even try and pass the sound station. What is the rule for sound? three strikes and you are out or?

With an exhuast bypass, you may not even be able to get this technique to work. In fact, if the sound police are "roaming" you will be too noisy in any gear. Hence, there is a very good possibility you will simply be wasting your time if you go to Laguna for a 92 db event. IMHO
