I posted this question last week in the camaro motorsports discussion and have yet to get an answer,so maybe it was in the wrong place.I used to race superbikes,and one track i never got to do was Laguna Seca.I am going to be doing track days with my 1LE. Laguna Seca has a decibel limit, i think 92 or 93. Does anyone know what decibles our 1LES will be putting out at full throttle? Oh yeah, here's a really cool pic.

I don't know any answers to your decible question but that is a very cool picture!!

I placed a order for a 1le today and went for a test drive with the npp exhaust. I don't know about decibels but that is one sweet exhaust note.

Thank you,was having the time of my life.

A decibel limit on a race track? That's just not right.

PYROLYSIS · 11-17-2012, 07:55 PM

Don't know how many decibels it puts out but I would imagine it should be fine. What kind of race track has a decibel limit? Only in California. With all the cars that have been on that track it doesn't make sense to have a limit. Maybe it's only for certain times.

CrystalRedTintcoat · 11-17-2012, 08:31 PM

You have to think like Larry Ellison, CEO of Oracle. There's a decibel limit for jet engine noise after 10pm in San Jose. He just pays the fine.

cornerspeed92 · 11-17-2012, 08:34 PM

Yes im sure it has to do with the snobs in wine country,i mean MotoGP runs there and they certianly blow the noise barrier off the chart.

radametz · 11-20-2012, 05:57 PM

I'd have to imagine that if the dual-mode exhaust is street-legal, then it will definitely meet the decibel requirements for a racetrack.

cornerspeed92 · 11-20-2012, 06:36 PM

Thanks,i would think so too,just checking.

I run the OEM dual mode with Kooks LT headers & hi flow cats. I also run a mild 2 wild controller. The two modes are loud and daddy that hurts my ears. I was surprised how loud it can get. I have not measured the dB levels yet.

newb · 11-20-2012, 07:17 PM

One of the reviews of the 1LE had a db level listed. I will see if I can find it. It was in the last week that I saw it.

Looks like you would be cutting it pretty close

Mgizzle · 11-20-2012, 07:36 PM

Many tracks i go to have decible levels.... U will be fine with the npp. It is loud and nice but nowhere close to race cars meeting those levels.
