Just take the mufflers off bro and run the header only. Will be very loud and chicks will notice you.

I'm also curious why this is something you want to know?

If you are purposely trying to make your bike as loud as possible....well that's a special kind of stupid and the rest of us who enjoy dirt bikes would appreciate if you found a new hobby before you go ruin riding areas and get them closed.

FYI, I build to order and you can pick muffler length and core size, no extra charge. On top of that Vital members get 20% discount.

I had a Jemco down pipe on a 2006 CRF450 and failed tech at one of the AMA Pro Indoors. I was 117db. They told me to correct it before the heats started....

Did your neighbor piss you off? Are you going to do some 3 AM panic revs towards his house? Asking for a friend.

Don't know if these guys make one for your bike or not, but I just put a Big Gun system on my 2015 KX450. Sounds like some NASCAR shit, awesome!

FMF by far. Take out the inserts.

I have a question about the exhaust sistem. I am thinking about buying a double fmf for my 2017 but i can’t find one for mine, only for 2019+. Do you know if it fits?
