I do not know where you think you read that but I donot have a FuelMoto pipe. Just looking at the pictures for the Fuelmoto M8 pipe lets me know it's not what I would want. Looking at it, it is a stock set of primary pipes welded to a new pipe that replaces the cat area, no "X" collector and short primary lengths doesn't improve the lower to mid RPM area's where we spend most of the life of the bike riding and that is the main area I look for when setting up a bike for use on the street.

That's my mistake, I got "Steve's" mixed up, Helton and Cole, sorry! I do like the Fullsac just struggling with the price!

I loose no torque with the Fuel and gain everywhere. I may swap it out but ONLY for a 2into1 when I do motor work but maybe not as it has a removable collector and is already like a stepped design so maybe it will be fine...

Picture of my bike for comparison

I did too but after all the other money we spend on these, I just said let's give it a try. I was pleasantly surprised at how much it gained and where it gained it at. In my book this one is a winner and worth the money.

Run 19 fully tuned with FULLSAC MX head pipe 5th gear
Run 20 fully tuned with FULLSAC MX head pipe 6th gear

All runs SAE, same day same dyno same tank of fuel. No changes to anything else on the bike during testing and the same mufflers used for all testing.
How did you get 20 HP and 10LB torque out of the stock bike and pipe ???
These numbers look more like a stock CVO 114

Does it push the slip ons back any further?

Any issues with floorboard clearance, I have Arlen Ness deep cut boards and they are quit a bit bigger than stock.

I did not look real hard at that. I would say they are pretty close to the same as I did not have any trouble but the stock mounting bracket for the mufflers slides back and forth some, so I did not really pay attention. Everything fit right back in place just fine.

None in that area, they fit same as stock head pipe, so if they clear the stock head pipe you should be good.

FWIW. I have received one of these. I installed it on my RK. Fits great, sounds great, runs great. So far motor only has a ventilator AC and Fullsac Re-cored mufflers. I am running it with a V+H FP3.

In my opinion, I find the price more than fair for the materials and workmanship on this piece. Nice job Fullsac.
