Anybody do this? I see complete kits on ebay with the head pipe and can for $50 shipped.

These don't route the same way as the 70 does, will it clear the plastic?

Also is the bolting flange correct? Pipe dia correct to fit in the 70 head?

A little trimming and bending doesnt bother me. So long as it is actually long enough.

Shoot me your thoughts on this.

Interested to see this aswell. How about those chinese exhausts?, they are cheap and shiny. I need one for my Z50 and atc 70.

I have one on my ATC 90 . Had to make one little extra bend so it wast too high up. I am going to be assembling my son's 70 this weekend and I can see how it fits on that frame and let you know .

The quality isn't the greatest on all of the pipes. $100 gets you a pretty nice one though. The $50 ones are very thin I found in my experience.

Yes you can make a crf50 knock off pipe fit pretty easy with a couple well placed bends and a little heat sheild on the plastic, yes they are long enough, and yes they are LOUD, works good for a cheap header, I like the high pipes for trail riding, I flat track- circle track my 70 trikes so I don't have to much use for them but my new build has suspention and needs a high pipe :D

Thanks for the tips. Are the more expensive ones a little quieter? This thing is a backyard BBQ cruiser, so I dont want it to be obnoxious. I do have a stock exh on my other 70, but was looking for one for the first one I got.
