Kaz the SW single was happier with stock Y pipe, and happier still with the stock quiet muffler instead of the loud SW can. Results posted this coming week (end).
Kaz your results have inspiried me, the HP Nazi, to drift up into the 150+ HP range for trail riders. Last year all DTR tuners know I would suggest stopping at 144-145 HP to hopefully be reliable. You and a few others have had good reliability in Canada on long high speed trails at 150 HP. Bizzare. But we're stepping it up a notch this year. 150+ is easily made with good timing/ fuel and either Speedwerx single with stock muffler, Bikeman F7 mod stock pipe, or D&D monster single. all need different fuel tuning, I'll post some stuff on each in the upcoming week.
you guys have no idea how lucky you are.

my sled is the one that was tested at dynotech with the speedwerx single and dd y pipe. i am going to say right off that my motor has been ported and has other work done to it, so i dont know for sure what the results would be on a stock motor with this combo..... but my motor made the most peak hp with the speedwerx single, stock ypipe, and stock can(versus speedwerx can). we tried many exhaust combos, including all stock parts, bikeman pipe mod, etc... the dd y pipe did seem to broaden out the torque range a little bit, but not enough to warrant 90 bucks in my case. hope this helps answer some of your guys questions

peak horsepower with speedwerx single came in at 156.1, best for the day. could have gone leaner with this setup, but didnt until i put on the dd y pipe as i figured that was where i would get my best numbers. i had to drop fuel pressure with the dd y pipe in order to match the 156 number set with the stock y pipe at a richer setting. jim also thought i would benefit from a higher degree timing key as i had the stock 04 box with only a 2 degree key in it, which, as everyone likes to put it"wasnt one of the good ones" so there is definately room to gain a bit more but that hp number is with plenty of fuel at wot, so i am happy enough with it and should have no worries this yr as far as reliability issues. wished i had a set of twins i could have tried, but beggers cant be choosers, and provided i get the clutching right on, it should be a good year for the 700 class
