Hi! I'm new here but I've had my 08 250 for about 7 months and I'm wondering about all the possible ways to make it quicker. I have a Two Brothers carbon slip on and a stage 2 jet kit already. Would a full exhaust make it that much faster and is it possible just to buy the headers and not the FULL system considering I already have the slip on? And making the rear sprocket smaller would make it how much quicker at the cost of how much top end? I'm just looking for guesstimates here. thank you!
