lol dont buy a 60-90 dollar muffler because its too expensive but tell them to buy telemeter equipment. Now that funny right there.Stock engine with baffle removed is plenty fast. maybe to some. i think CP and I will agree that there is no such thing as fast enough and fast starts at 120+
A stock jett 46 will turn a APC 9x8 at around 17,000 with the red muffler on 15% fuel. Work it over and you will see 18,000.
