track days and hi-flow cats

[hagar]

Just wondering, if I go and put the hi-flow cats on the car, is it likely the car will be over 95dB? I ask as I am doing more track time in it this year and don't want to be turned away due to noise.

 

Also can anyone explain what the noise increase is like? Is it really noticable in the cabin?

 

Thanks

never heard anyone with just cats and oem zorst mate, so can't help mate

 

But i'd say you should be still within the limits, maybe?? as the measurement is @ 4000rpms isn't it?

I think you would be fine. 95 is one of the lower of the db limits. Donington are very strict and have a 98db drive by limit. I always get black flagged in the Cossie there, but this car is loud and I mean LOUD!!!
