wow! 1 square inches by 14 inches long for 6,000 rpm. It looks like the stock tuning is indeed closer to 1.5 square inches at 9.8 inches long for a peak of 8,700. I would have to make a major mod to find room for 4 more inches of length. Would probably have to add a 90* elbow. I wonder what the gain in torque at 6000 would be if I bother to try.
