Those Pitts mufflers suck power and cause nothing but problems with lack of fuel tank pressure and noise. I'd rather spend the $60 on a Jett muffler (tuned about 1k rpm higher than the Tower muffler that was sold with the GMS and Tower engines) that has a bit more latitude for prop choices. Full tuned pipes can be peaky on certain engines and they're expensive... I would consider the tuned muffler before the stock muffler but above the Pitts by a mile and a half.
