Are there any single pipe / can setups out there for the 850's? If so what are the HP increase claims? I'm guessing the aftermarket world is having trouble getting any more HP then the stock pipe??

I don’t think they are having issues getting more HP than stock, I suspect tuning the new ECU is proving to be more difficult and complex than originally thought.

Not to hijack the twin pipe thread but has anyone had the pipe mod from bdx / ssi done to their stock 850 pipe? They are claiming 9hp with no fuel tuning required so it seems like a good hp gain for the money.

I had my first day on Bikeman single pipe and can for my 850. Sounded good and I picked up 150 rpms on a really deep pow day. Will need a couple more rides to really comment on performance but seems good so far. No codes or hick-ups or anything strange through 9 gallons of fuel and the flipper on the bars most of the day.

Nobody I talked to recommended pipe modding the 850 pipe. SLP told me no single this year and few more weeks for twins. Twins will come with glass packs and be loud which was a deal breaker for me. Jaws said next fall for single too. I liked Joey's (at Bikeman) dyno videos and looked like them put a lot of time into the 850 pipe\can set up. Ordered on Monday and received 3 days later even though they thought it was going to take a week to ship.

How long of WOT were you? The "long WOT" section of the dyno video was not acceptable for me. Starts at 175hp and then climbs to 182hp after 15 seconds. Holds that for 5-ish seconds and then starts falling. 20 seconds later its way down to 164 hp and falling fast before he stops the dyno.

The hotter pipe temps created by running the pipe making more power causes the ECU to respond by adding fuel. Our programming will address this and many more issues that stock sleds are having. We will have performance reflash tunes for all stages of build. Most people do not hold it pinned for longer than 30 seconds but if you are one of the ones who do our Bikeman FatAzz pipe is still better than or equal to a stock pipe sled. Once the programming is released it will crush a stock pipe in all amounts of time held wide open.

Will this pipe / can combo be much louder than stock?
