Just a quick question, I went back about a dozen pages or so and did not find a clear answer to what pipe is the best for mileage for a truggy, as this motor is going in my sons 6t, and right now he was running an older version of the os-vspec,and can get 10 minutes or better, so now I was thinking about the jp3 for the new arrow gtr, but now after reading the last few pages seems that they are not going to help the mileage and may hurt it, so please help if you can

any thoughts on a os 2050 pipe???
