Exhaust Valve Help - Urgent

Kam · October 13th, 2012, 09:30 AM

I'm currently at the Nurburgring and have the nightmare of not being allowed on today due to me hitting 104db static.

I need to try and get it below 100db static so wondered if there is way to close the exhaust valve for the static test.

I'm going to try again tomorrow but 4db is pretty hard to shed.

Try wet mode, might help.

Get to the valve and fix the cable to the valve in a pulled position. Might eventually hep. Another (possible) quick fix might be some steel wool or a wooden stick (i seriously heard that from guys who took their race exhausts to the TÜV inspection) . No guarantee....

Wasn't there a trick with the clutch pulled at 5500rpm?
