REFLECTOR: Exhaust noise

[Scott Derrick]

I'm using a Custom Aircraft exhaust which is fairly similar to the 
factory supplied exhaust. Basically a 3 into 1 stack for each side with 
the outlet pipe pointing straight down.  The factory exhaust joins  the 
3 together under the forward cylinder. The Custom exhaust joins them 
under the middle cylinder.

I got a noise ticket(warning) in the mail from the KSMO operating 
authority last month.  They have a 95db limit that they somehow 
monitor.  They said I put out 95.1 db on one of my departures that day.

Anybody else experience this? Any solutions?
