Reply To: Exhaust? – GV125C
I assume those are still stock pipes.
If you get a string. Wrap around the part of the headers that connect to the cannons. Ie. String is 38mm end to end , so the headers would be 38mm, you would have to get some kind of reducer from 38 to 30mm, then find 2x long long cans that are 30mm – If the cans rear the back tyre like your old ones, then it should be okay with a baffle hole that is about the size of a 10p coil. This is an example as i have forgotten off my head exact diameter of the old style twin pipes but i do know about the single cannon pipes as thats most common on later GV125s.
I believe Amazon might have such cans, ebay is a wild mess of chinese things nowdays. Failing that you could have someone fabricate a Y shape pipe that takes 2 pipes in to one single pipe , then you could have maybe 32mm to 40mm cans that should be about as long to reach the end of the swingarm. You won’t loose too much power and still get a good sound.
Remember though any changes to the air (exhaust or intake) = upjet the carb so the bike doesn’t lean out.
There is a tutorial on the forum on how to safely remove the airbox without damaging the super rare intake manifolds.
