356 Muffler for Laguna Seca

["Trenholme, Phil" <Phil_Trenholme@affymetrix.com>]

Hello,

I am looking for a muffler for my 356 racecar that will get me past the 92db
requirement at Laguna Seca. My intent is to race there more often and many
of the events have the 92db requirement. Previously I have just bolted a
street muffler to my Bursch racing exhaust but this really slows the car
down. I am hoping there is muffler that I can get that will hurt my lap
times too much yet still keep me competitive at Sears Point and Thunderhill.
I have heard a Phase9  muffler will accomplish this. Does anyone know if
this will work or where to get one? 

Thanks
