HI all
I have a Znen 150T 150cc chinese scooter

I want to do some mods to it, does anyone know of a true exhaust that I can add to this scooter that will open the motor up so the engine with the proper intake and jetting can breathe, not just something thats a little louder, but something that truly increases airflow/output?

TY

I'm new to this forum, but a long time skeptic of performance exhaust systems. Do a little googling on this subject. Exhaust manufacturers will make claims of 10% or more improvement to horsepower, but reality seems to be in the range of 2 to 3%. You may need to look modifying intake as well to see end-to-end gains. Personally, I think there are other mods to consider such as a performance variator that might give you better results.
