I was looking to get more power out of my 40 FX on my magic . would a tuined pipe give much extra power. I was thinking of carbon fiber were would you get one. will a 40 FX turn a 12*4 prop Iam runing a 11*5. I need a little more power do to my high elevation 5000 ft. would a tuined pipe be lighter thin the stock muffler it would proubly get the CG back more .
