Zoot, I also noticed you installed a rubber tube to the rear pipe outlet. Did you notice an change in tune. I know that the rubber tube can affect the pipe tuning.

As for me, the Team Kyosho SDW011 tuned pipe exhaust came in today. Looks sleek with its angled mounted one-piece design. I guess I can check to see how the stock, Sirio and Kyosho pipes work/feel on this engine soon. Seems to be a straight through design. No side tip outlet.
