150cc exhaust questions

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.
