Guys, I know that a lot of you run the ys four strokes with the tuned pipe with the tuned pipe.
I really would like to know if this is a good match. I have been told that this setu p causes lots of engine problems, even lots of breakage of engine parts. The reason I am so curious is that years ago I purchased the pipe and engines but never used them, I would like to use the pipe on my ys120 sc the motor runs great with a little standard muffler but very loud and I think the pipe might help with that. I don't need ant extra power just want to use the pipe.
Is the setup different with the pipe.

Please give me any knowledge that may help on this.
Thanks in advance
Jeff
