Horstman header / muffler for a mini ?

[race]

Short of a full-on expansion chamber it seems like these are rated the best way to go for two-stroke engines. But kind of tricky with double spouts to deal with. Has anyone tried or have pics of one being used on a mini bike? And how does their sound output compare to ... say an Azusa with the full end caps?

I don't know but that setup looks friggin awesome. Is it yours?

What engine are you looking to use on this minibike?

I have never seen one of those. Can you slop a short elbow on each outlet to blow it out the back?
That kart is beautiful.

Hey ... I wish it was mine. Just pics I snagged, probably from here. I'm working ( slooowly) on a Taco 44 with a WB 820. The thing is, on a kart it's all stuffed behind you and there's plenty of room. On a mini bike you have far less room, need to stay clear of the chain line and not fry your foot or leg ( two spouts! ).
