RD350 AC 2 into 1 pipes on Ebay

[So-Tex]

A Japanese seller on EBay is offing a chamberish style cross over 2 into one pipe for AC RD250-350's as well as other Rd's and RZ's.... anybody have any experience with or thoughts on the style?

id be more inclined to get the spitfire ones out of indonesia than these. 2-into-1 2 stroke pipes kill all topend on a street bike. I have ridden a triple, and a twin w them. def not great most of the time. my 0.02

Thanks Mark, I appreciate the feedback on the 2 into 1 configuration.

I had no idea they even made such a thing!

Based on the physics of 2-stroke tuning, a 2 into 1 would be a terrible idea.

That - and it just looks so wrong!

lots of sleds run similar,  and are ok, and I have ridden a reverse cyl banshee powered ninja w one that was pretty fast. but, still, for a street bike id stick w individual pipes. some of the gt750 guys love them,  but..  depends what you're after. on an rd though? no. id bet they would work well on a radjoot low torque motor though
