Sound Level Requirement - Porsche GT4


John H

Recommended Posts

I have a new '22 GT4 that I intend to bring to solo events this year at AMP and I'd like to make sure I meet AMP's noise level req before I show up.  The car is completely stock: no mods to the exhaust system or the intake at all.  Will it pass the sound level test as is?  And if you think the answer is "no", any recommendations on mitigation hardware?  It is very difficult searching online for something that works.
