Re: 1979 G1 exhaust.
No exhaust will mess up just about any 2 stroke. Some have used other pipes usually have to cut and weld them to fit in the cart. A lower rpm pipe might work like a blaster pipe, similar cc engine. You may have to change jetting, more porting may help too. The G1 is built to run about the same rpm as the 4 stroke which is shift at 4K max more or less, so 2500-4200 range. Being a 2 stroke it will rev much higher though with less power output. Anyway a pipe for low rpm will be longer, the G1 pipe is long inside the muffler plus the outside pipe to get more length and tune at lower rpm....though it does not tune that much because its not a performance application and also has to be quiet. More power tuning usually means more bulge in the pipe. Its also a reed engine which is different than a piston port 2 stroke. The easiest way is put a stock type pipe on and it will work and fit the cart.
