I've never checked decibles but it is conciderably quieter (probably not able to pass though). Ive never been checked. Hope I never get checked either.

 

Hey Jad what is the number at BigGun I have a couple questions regarding the exhaust I bought. Did you ever send him the spark arrester?

 

I did send it back but that was only a couple of days ago. 909 948-7029
I saw you had a K&N filter listed. do you have it installed yet? Does it hook up to the Pro-Flow?

 

If you notice I wrote -back order because they have not made one yet I ordered it from Yamaha but they have yet to hear anything.

 

Hi Sonic,

Can you tell me what size main jets you are running? I just installed my Big Gun 'Quiet Core' exhaust and I installed the recommended 150L and 155R with 27.5 pilots and the bike is running very rich. I'm going to try and install 145L and 150R to see if the rich condition gets solved. I even tried running the bike without the lid and it was still running rich, so rich that my eyes were tearing! Any information would be greatly appreicated.

Thank You,

IronBear

 

I've got DynoJets #146 & #148 and their needles (middle grove). This is what they recommended for my altitude. No problems, this thing rips! I've also got six Uni's in the lid and hogged out the intake on the cover. Hope this helped, I just got back on-line today after my computer was in the shop for three months. Wish my computer ran as fast or as good as my Raptor!
