Anyone have any good way to lower your car's DB noise levels at Laguna? I keep tripping the sound above 90 db. Tried upshifting, and lifting, but if I lift any more -- I won't be able to maintain my speed
The only thing I have heard of is physically changing the characteristics of the exhaust, may sound very crazy, but you can get a customer DB killer made and weld it on. Still, again, no one would suggest that as..who wants to do that to a supercar!
