i got a 650sx OEM head pipe/SS chamber for free and picked up a FPP 61X exhaust manifold for $125 and did this mod to my kids FX-1 with 650 motor. I also added in a 4" SS extension that I cut off the end of another 650 chamber that I had. This way its more like a ltd. chamber. I did the water routing mod also.
It works great! I had to fatten up the carb quite a bit and could feel the extra power. That OEM pipe is the biggest POS and its bulky and heavy.
This was a great cheap mod... Thanks for the idea Gorilla.
