I finally got a new pipe. I had a Big Gun on order since March, and when I got tired of waiting, I got a Two Brothers. Wow, this pipe is loud! I'll get the insert when they are available. I noticed there was a little poping when I close the throttle quickly. I may have to open the fuel screw a 1/2 turn.I know it pullsharder and revs quicker than with the stock pipe, but I also put a 45t rearon at the same time I put the pipe on, so who knows. Here are the specs.125 main, 40 slow, needle on 2nd clip, fuel screw 2t,slide & vent drilled, KDX snorkle, Two Bros slipon, stock air filter w Notoil oil. I'll update as I put the miles on.

 

Nice, maybe ear plugs are in order.

 

Yep, my HMF slip-on is pretty loud even with the Quiet Core but it makes me feel like I'm 19 again and it's cheaper than therapy.

 

The two bros quiets down quite a bit with the insert and still sounds good.

 

With the new jets my bike starts without the choke. I'll have to ride it some more to see if it fouls a plug. Also, I took the snorkle out. More later.
