I'm in the market for a exaust system but I want to get one that is quiet enough for the Oregon dunes I think that the limit is 90 db but I'm not sure any help would be apprecaited thanks

 

Good luck!

 

The stock exhaust meets that. Your best bet is to use that one when at the dunes, so that you don't get a ticket. I have heard the ticket is only $15 if you can fix it on the spot, so maybe you could carry it in a backpack with you if you really have to have a more powerful pipe. -This last comment was a joke BTW! You ought to start with the more basic things, like a K&N or Uni filter for your DS, though I haven't even heard anyone in here mention a Uni filter for the DS, guess everyone is sold on the K&Ns.

 

Might try the new Big Gun with the quite core 94db. I don't know if that is low enough

 

I have the uni on my DS and it works great.While most of you run the K&N I am just a little gun shy of it.I agree the K&N makes a little more power but you have to ask yourself why the winning Baja 2000 team and almost all other cross country race teams choose a foam type air filter

The Uni works better in high dusty conduction and the K&N works better in sandy conduction. Some people run a K&N with an outer foam filter as a combo.

 

The DB limit at the Oregon dunes is 94 DB.Good luck,im sure with a little looking you can find one to meet that limit.Which is a ridiculous one at that.

 

the real numbers on how they test it & what the current limit can be found at www.oohva.org

they have a section devoted entirely to this topic

 

Sorry if I was misleading, I read 94 DB in a mag.Good luck.

 

Current allowable dB level for the Oregon dunes is 93. It is 97 at Sand Lake, where ever that's at.
