This is dyno results on my 900 after modifying my cobra longs. The combo is 1 3/8" head pipes 12"long stepped to 1 1/2 " for 18" or so. 1 3/4 straight through after that. Sorry the air fuel is blurr. I keep it under my seat and it got wet. I am thinkin about doing a low buck cam swap this winter just havnt had time yet. I made a mistake in my post before stating the before and after combo. Both runs are with the same pipes but with different mapping. I apoligize. I was not trying to misrepresent anything.When I took the bike to the dealer I was having it tuned because of the changes I made to the pipes. So my mindset was I was going to see how my new pipes did compared to my old ones.I was really happy with the results,but as someone pointed out to me my dyno chart is not one set of pipes to the other. It is just the mapping the new pipes required and the results of that mapping. I am so sorry for the confusion. I was not trying to mis-represent anything. I feel like an idiot.
