Probably not. You may loose too much backpressure with a bigger motorcycle exhaust which means going backwards with your engine performance gains from that kit. That is if you can find someone to make you a header pipe to fit on to the muffler as well.
I'd just rather buy a pipe already made, and I'd choose Takegawa exhausts because they make a good power on pcx, rather than just the look and sound you would get from all the others. I assume you are running a 150 head with bigger valves, so you would have to make sure you get the exhaust that is made for the 150 motor . The header pipe is slightly different than on 125 model because of the engine mount repositioning..
