Any ideas what kind of restrictions are on the GP pipe?

yeah the down tube restrcition is only in the euro spec pipes normaly they come with a big tag on them that says warning do not remove this
the thing is the gp isnt a very high reving pipe
infact even with a kit on there it only flows about as well as an oem yamaha pipe

Had way to many issues with my 70cc kit. So I'm back to 50... This Gp exhaust is real smooth. Very happy with it. I'll post some pics

Nice scoot. I wish I had mine up and running. Thinking about just throwing a 90cc engine in mine and calling it done for now.

Thanks for the pics. Best looking pipe I've seen on a scoot. Very cool piece. Sounds like it's not as bad as it's made out to be. Sure not the best performer, but if you keep the cylinder you use mild it should do OK.

Yea I just went through and installed all the cvt parts that came with it also and moved my contra spring back to stock... Goes pretty good at this point hits 7.5k almost instantly and holds that rpm till you hit 35 and it gets there in less then a block.... Very impressed how much of difference that made... Had it up to 45 and then pulled back. So I can get a little more I think if I wanted.
I ordered so 4.5g Dr. Pully's last night ill let you know how those work also.
It may not be the best pipe but for style, sound and overall ride, but its way better then the expansion pipe I had on it.
