Borla Atak dB

crispy tofu · 03-28-2013, 09:41 PM

anyone measure the decibel level this exhaust makes?
Laguna Seca and other area tracks have pretty restrictive noise limits.

what's confusing is Borla says this is the "loudest street legal" cat back they make. not sure what they mean by that. Trying to determine how much risk i'd be taking with this exhaust...

I'd guess you'll fail if you WOT up 5->6

Even a stock M3 gets close.

Oem xpipe?

I pass with my afe xpipe and oem rear exhaust.
I might pass with my vorsteiner rear section with oem xpipe.
I'm at 96 dB with my afe xpipe and vorsteiner fear section.... I went on a 105db day at laguna and asked for a sound check with my loudest configuration.

You might be ok... it's really hard to say. You'll be at the top of 3rd gear going uphill at full throttle while passing the sound booth.
Try to replicate that scenario and have someone point a decibel meter at you from 50' away.
