Hey everyone. I just bought a 65cc metrakit for my Puch from treatshq. I'm so stoked!! I've been waiting for one to get in stock when I have money!! But, I have read that you need to get a performance pipe. I want one that has really good low/mid power, and not so much at the high range. I mean, I want to go fast and all that, but i really like to have good low end. What do you recommend? Now your wondering why the title says "modifications". Well, have any of you modified the stock pipe to allow me to use a good amount of the kits power until I can sell another limb/internal organ to buy a pipe. And if there is a way to modify a stock exhaust, would it affect breaking in my kit? Smitty, you might be able to answer that. I just have this gut felling that it is reccomened to break your kit in with a good pipe, not a "homemade" one.
