Guys,

I'm having some problems getting by the noise limits on couple of our race tracks. When measured from the exhaust at 4500rpm, there's no problems, I'm at about 90dB there, but when they are measuring the drive-by noises, I'm clocking at little bit over 100dB and the limits are 95dB. So a little problem here as 4 out of 8 races this season will be held on 95dB tracks.

I'm running a 48mm CF-DTM intake with Lee's filtering setup. Any ideas how to get the noise down about 5dB's? I'm going to try a some kind of a sound reflector in front of the collector/Lee's filtering panel, but would be interested to hear how you guys have come around this problem?

Thanks!

Mikko
