I went with the 255 for warranty reasons and I was looking for a nice hit on the bottom end with just a bolt in. The 255 is still an emission's cam and will not really cool things down, I'm going to do that with tuning. If I was to say screw the warranty and pick a cam based on what I want I would be looking at the Head Quarters HQ500 cam which is also a bolt in, just later intake close and more overlap which will help cool things down. The downside is you need to be good at tuning because your going to have to roll your own map unless you find a dyno.

There will certainly be a difference in performance and heat between our Jackpot 2/1/2 vs. a modified stock non catalyst headpipe. The performance increase is due to our headpipe collector design and 304 stainless has superior heat dissapation qualites over the steel stock piece. There are also specific dyno charts comparing these headpipes on a 09 touring model at www.jackpotmufflers.com

Heat wise I wouldn't expect there would be a difference between the Fuel Moto head pipe and a non catalyst head pipe. Performance wise you be the judge, below is the text and a dyno chart from the Fuel Moto web site. Cost, yes the Fuel Moto solution may cost a bit more vs a 09 head pipe, that is if you can weld in the bungs and get the location correct and find a muffler shop to make you and extension piece. Myself I wasn't looking forward to doing that and I can tig weld the bungs in so my cost would be just the cost of the bungs. My concern was getting the location correct, get it wrong and you can have issues with performance such as surging, pinging, and more vibration, all signs of a poorly tuned engine. Jamie at Fuel Moto has taken the time to work out a combination that works with both the 09 and the 10 O2 sensor locations, I wasn't willing to reinvent the wheel. I'm thank full he has decided to come up with a solution for the Triglide crowd.

"The dyno chart below is a direct comparison between the stock headpipe vs. the Jackpot 2/1/2 headpipe. This comparison was done on a 09 Touring model with Stage 1 air cleaner, Dynojet PC-V and Jackpot Dyno Tuned mufflers. The headpipes were tested back to back on the same day, in the same conditions, at the same engine temp."

I’m confused! I thought that the whole purpose of Jamie requesting a sample set of Tri-Glide head pipes was so he could design a set of “True-Duals” for the TG?

Please, please, pretty please tell me I’m correct! I want true-duals and was hoping that Jamie was the man to do it!

Out of Warranty

I think most are going with the 255 because of the Manifold Pressure on the old Harley Air pump. The design gave the MAP sensor fits on the early Fuel Injection. The Atmospheric Pressure is all over the place with a more agressive cam. The Delphi system is more dependent on MAP.

At any rate I see a lot more of the 255's going in as compared to the more agressive cams on the big cu. in. late models for street applications.

255

http://www.nightrider.com/biketech/camdb.htm

For street manners and drivability it looks like the 255 is a good choice when leaving the compression alone, which is recommended.
Taken from the 07 and up 103/touring chart!

We do not produce or generally recommend true duals as they negatively affect performance in many applications, especially in the lower RPM's where most are looking for increased. Athough far more difficult to design and manufacture, a 2/1/2 offers better performance on these low reving motors. Our 2/1/2 makes unmatched Hp/Tq to any other headpipe we have ever tested.
