Exhaust Exhaust Manifold?

[geebt48cc]

Hey folks,

Well, I got the JNmotors exhaust manifold extension today as a gift?!~ Well, just wonder if I'll notice any change? I've heard from some friends that they really don't do much? Hmmmmmm, anyway, I'm going to give it a try.............Why not!

I thought about trying that, also... let us know how it turns out. I don't think any one mod would make a huge difference on these little engines, but 1/2 horsepower here and there add up, plus an exhaust improvement sets the table for intake improvements later.

Hey there Purple,

Yeah, I've got it on bike now, but can't use yet do to weather. LoL, it does help the engine look more official?! Time will tell.............

With an expansion chamber it lowers the peak "tuned" rpm of the engine by 400 so that the powerband is that much lower.

The exhaust extension is a handy way of moving the exhaust pipe further away from a large diameter down tube; giving more air gap between the pipe and bicycle frame, especially if it's made out of thin wall aluminium tubing.

I use them all the time for clearance reasons. I don't know if they do much.
