I have a stock motor except gov bypass and exhaust. Starts frosting to the point that it affects performance in non race conditions . The exhaust uses stock size header pipes at least a foot long before going 2 into 1 with 2 inch pipe about 2 feet long. Is it more probable that I don't have enough restriction or possible Carb problem . Runs great till it starts freezing.
