Stock Dc2r noise EPA

[nomoney]

Hi,

Does anyone know how much noise a stock audm dc2r should be making at 5925rpm? :confused:

Below 90db. Best way to pass the noise test is with a stock exhaust.

I tried going to a muffler store and putting on a restrictive muffler on my twinloop as I got my noise test tomorrow. Can't seem to find a stock exhaust anywhere or an audm cat or header.

Do you think a twinloop bpipe, jdm cat would put it below 90 with the new muffler?

Probably a stupid question as you don't know what the muffler looks like.

and for additional information it ran 96db last with the twinloop muffler

Good luck. Your going to need it.

Too late to do anything now.

Thanks

Stock DC2R full exhaust = 87db

I got .1 below the legal limit on stock exhaust and headers/cat so barely passed
