I've seen noise limits of 90db, 92db, and 103db for LS.

90db: Hooked on Driving, NCRC
92db: PCA events
103db: Racing

Yes, but most days are 90. Who can contact shark works and get the, working on this problem? I would pay a good bit of money for a solution, and I am sure there are hundreds of other cars that would as well.

I got black flagged 4 times during the Porsche Parade weekend in a stock Boxster S and that was with a 92db limit.

Yes. All 5 cars were on the stock exhaust. One even had a diverter.

I doubt the valves will knock 10dB off, and I'm sure there would be a fairly unfortunate loss of power due to it (if not a larger failure).

So who can make reliable muffs that can easily be attached for a track day and pass the 90dB meatball test ? That could be a real money earner...Sharkey, GMG, Evoms, ect....just say in'

Aren't the valves closed all the time when you don't have the PSE button pressed?

If that's true, I still had no trouble hitting 100dB. I didn't have the PSE button on the whole day.

Here is the cup car in front of me at Laguna. check out this exhaust system, this will look good on your new GT3.
