Hmmm ...
Gtc are you concerned that your car may be to loud?
If your car runs any type of street mufflers then you should have no trouble at all even if you consider it to be to loud for the street. The way it's measured for the street is completely different to the track.
There is a db meter in the middle of the track so if your car is too loud as it goes past it you will soon know about it by one of the track stewards. In saying that though i have seen many loud street and track cars run there without any issues. Andy's car ran there last time with no issues and Boschies track car complete with a side pipe had no problems either.
A mate once got pinged there for noise in his rotary powered sports sedan but it was f*&%! loud. The rest of the field of sports sedans which mostly run V8's had no issues.
