Default Lowering your Track Day exhaust noise?

Anyone used any products or got any trick ideas for getting the dB down for track days?

Mine measured 109dB on the static at Bedford so looking for a way to reduce it for other tracks?

I am going to get the exhaust repacked that should help a bit but any other ideas or tricks?

Doesn't this make the exhaust more restrictive, thus making the turbo work alot harder????

Not if they are designed properly. Only makes it more restrictive if you start adding bungs etc...

cant you use earplugs? or muffs........

depends to what benifit your after, if its for yourself i would use earpieces before i put any kind of restriction into a tuned engine, but if its the car in your siggy then wouldnt any sound muffling be deminimous due to the tailpipe to driver distance?
