Sound regulations question

Recommended Posts

I'm considering putting an aftermarket exhaust on my car, but I'm concerned about breaking sound at events.  I see the limit is 96db @ 50 feet on AMP's site, but it doesn't specify throttle or rpm range for this test. Can anyone shed a little more light on this?

As long as you keep the cat on you should be fine.   Note that the intake you run can make a difference as well.   Stock intake definitely quiets it down a bit.

Yup, was thinking high flow cat in the future (not a test pipe, I'm not here to be obnoxious) and leaving the stock airbox.  The dyno testing you can find on YouTube proves Honda didn't' skimp on the intake on these S2000's!
