Just be aware that both styles can potentially hit your leg/foot easily, depending on the bike and/or seat positioning. The cdh67 is more prone to it because the chamber is bigger.
I'll have to build an adapter mount for it anyway due to the bt80 exhaust being similar to a 2 stroke dirt bike
Yeah they got a big ole exhaust mouth on them bt80's, you definitely will have to fabricate a flange. You could buy a $95 jog pipe & fab it to your bt80.
From what I read on the BT-80, it has a 35mm diameter exhaust port...Thats even larger than the Phantom 85 exhaust port which is 28mm with a 60mm stud spacing
I agree with this. If you have to fabricate, use the jog pipe. They even come with a muffler on them. So the cost vs a F2 or CDH67 + muffler sill be about the same.
Yeah they are like some motorcycles, I'm trying to remember what brand uses that type of exhaust flange.
The OD is 35mm, but like most motorcycle exhaust headers, it's a thick collar in order to seal against a crush gasket.
Also on your reeds, I think the CDH OZ reed valves are better than the G2 reed setup. This my opinion & have never ran reeds. But I'm fairly sure the CDH OZ reeds flow more than the G2 reeds.
I was already thinking of the cdh reeds. They seem like they are a lot sleeker.
