lowering my db readings

billyboysm3 · 25-10-2011, 03:10 PM

Got tested last Thursday at Snetterton and measured 113db

But the car was sat by the testing station for 45min-1 hour while the briefing was on, plus cold.

Got told to go home, luckily they let me re-test, after a nice drive around Norfolk admiring the views I measured 105db.

They did put the probes in the exhaust and I thought it was read from 1m away?

Car has Supersprint cats, centre pipe and lightweight supersprint back box.

Is it as simple as getting the back box repacked or to be total sure putting the OEM back box on (which id need to buy)?
