YFZ450 Big Gun Eco Series Exhaust

Installed the eco series big gun exhaust on my 2005 YFZ450. It's just the slip on with the stock header. Sounds so much louder than stock stock now. I also rejetted my carb after putting it on.

Do you have to tune it for this specific exhaust

[@ALuna244]

I just went up on my main jet from 158 to 160(I'm at high elevation). This is just the slip on not full exhaust. Didn't notice much of an increase in power, but sounds so much better now.

Do you have a video to show how to do it ?
