I hope you do dyno the drag pipes also. That will help me realise if removing the baffle will increase hp and tourq. Besides those are the ones I am interested in. I love the looks and sound of the slash cut drags. If i ever get my emplyment stratened out I'll be your next customer. Can you keep the center stad with the drag pipes?

Gordon.............backing up to the comments I made about your megaphones in regards to reverse cone design,here's a photo of a set on a Triumph,similar to what I built for my BMW about twenty years ago and sold. Whether you prefer open or close end mega's,the difference in power is like comparing an apple to a orange. Just something to think about the next time you get an urge to play around.

In my mind the way I am picturing all of this those pipes jack just mentiond or the long drag pipes (not too big of an inside diamiter) would work best.

Hey there, new member here, this is my first post, excuse me if I am supposed to say hello elsewhere but I felt I just had to post under this contentious topic. I joined just to do so!
I purchased a set of greatscotts snake charmers recently (they arrived days ago), Not exactly like the ones on his site. These are longer and wider, built exactly to the specs I wanted and needed. He delivered exactly what he advertised. The communication before, during and after the sale were fantastic! If you are interested in this mans pipes DO IT! You wont be dissapointed. If you are looking for all out performance you need to worry about more than just pipes! I do not desire to feed anyones arguement. As opposed to "backpressure" I believe the term "scavenging" would be a better concept to clear up this issues. Thanks once again GreatScott, the pipes are fantastic!

Gordonscott, that is exactly what I talked to you about the other day. I am wondering can you still get to the oil fill/check. If so how what is the outlet on the single? And how much for those fine looking pipes?

I like the look of that pipe on Jerrod's bike. What are the pros and cons of left versus right? I would think that left side exhaust would clear the way for kick start and oil check.

The right side pipe would be god for someone wanting to run a single carb out the left side, and for use with a jockey shift. Off the top of my head, without including the visual preference alone.

Gordonscott,
Some great pipes. Will the snake charmers fit on a basically stock bike?? Or do I have to do all of the mods like the ones in your pictures.

Have new tool to do long sweeping bends so maybe some new ideas will become reality soon based on this pipe? UPDATE: made a set with new bender...

Hi Guys, did another run, this time with the "glass pack hi-pipes" still on stock jetting and aircleaners. The glass packs came in 1st in power but lost power where you use it most, the "2into1" came in second in power but really gained power and torque where you use it (4,000 or so) and last was the stock system. I'm just posting results as they are, I thought the "glass packs" would do better as did Roy so not sure what the deal is there? From these dyno results I will try to come up with a 2into1 hi-pipe with reverse cone meg, I will make a nice design for left side and clear of any and all oil/kickstarter problems, will dyno that system in future. It will be the only pipe I have that will be based on performance. The rest will still be whatever you guys come up with and ask me to make, it's always been the "one off" stuff made for individual projects that have sold the most, and thats cool with me as I'm only one guy and can't make a lot of these anyway p.s. still slopy chain/wheel balance spike's in graph, sorry

And other bike was a little tired and this one runs as new. But think it was a 4hp gain? with jetting and carbs. I will look for that dyno sheet when I can, burried some place?
