140cc pipe recommendations

[Gplracer]

I finished my 1970 CT70 restore. It is fitted with a 140cc yx motor. I need a new pipe that flows well to take advantage of the motor. I would like some thing that looks stock but I am not sure if that is an option. Any suggestions?

I have two bikes with YX140 motors. On one I use a stock Chinese CT70 replacement and on the other I use a stock 2020 Honda Monkey exhaust, cut and welded to fit. They both perform great, power about the same, neither is excessively loud, although the Monkey muffler has a deeper sound that I like better. In fact, the intake is louder than the exhaust and a too restrictive air filter can be more of a problem than a too restrictive exhaust.

Here is an option. I use this on my 124 build. It’s been a solid exhaust for a few years now

Note that the CHP pipe, is only the pipe...no guards are included for that price.

Just checked my local Offer up and there are no less than 5 Stock Grom exhausts for sale, varying from $15 to $100. It wouldn't take too much modifying to make one work. Might be worth checking out in your area.
