I have a stock 1600cc Air Cooled Prime Mover. I have done some research about the stock HP being around 50-56. I was thinking of getting rid of the current stock exhaust and replacing it with a strait pipe system along with a small turbo to increase the HP to around 125-150. Would this be a bad idea or is the small diameter of the pipes enough to hold the boost in check? Thank you for all of your input!
