I'm satisfied with the power of my 2009 XB12Ss. I want to choose a muffler for the best sound. Will I still have to use ecmspy to make sure I'm not running lean, or will the newer ecm's in the 08's and 09's compensate enough to keep the fuel mixture right?

D&D lists their pipe as being available for 2003 to 2007 Buells. Do they work ok on later models?

I'm leaning toward Special OPS. Seems to work closest to stock ecm settings, while still providing a boost to performance and sound. I keep feeling I should keep that exhaust valve functional... correct me if I am wrong.

I put a Drummer on my '08 XB12Ss and it runs much better. No other changes except a previous breather reroute. Less surging and coughing at low RPM. The ECM seems to have self adjusted.

The above is as per my ride impression, I have not pulled plugs or put the bike on an analyzer, dyno, etc., but I am happy with the results.

If you want the ultimate tune-up, I think that you would have to reprogram the ECM.

Eicas, thanks for the update on your work, and thanks Boney for the search suggestions. I pick up my ride tomorrow, and have decided to keep it stock for now. I don't have the desire to spend more money on dyno testing, nor do I have much extra time to screw with fuel settings myself. I'll spend my little bit of free time riding.

I can't wait!!! less than 18 more hours, and I'll have my new 2009 XB12Ss. Bar end mirrors and headlight modulator, brakelight modulator are the only mods before leaving the dealership.

Stay stock for a while, atleat until its broken in a bit and you are used to the power, just so you know what you will want.

Special ops is good and cheapest...

The valve is something a lot of people like but I have heard after hacking into the pipes as much as these exhausts do, that it has very little purpose.

In terms of sound, quality, service and performance they are all close but I have heard the best things about drummer, its what I plan to get.

From what I have heard with stock everything, the drummer will have a good bit more power above 3,000rpm (and will seem faster everywhere, just because of the sound) and will run just fine.

Later on if you do an intake mod (high flow filter, open airbox etc...) and tune it you can get more power everywhere and a nice bit in the 2-3K RPM range, but the motor likes to be spun over 3,000rpm anyways so I would go drummer if you can afford it (its just a LITTLE more then the special ops) or Ops if you really want to keep the valve. It will still sound REALLY nice.

There is an exhaust shootout with video's, audio, dyno data with various fuelings (including stock) on the web as well...

D and D is super loud, Jardine has bad quality. I'd stick to the reworked stock pipes, specifically Special Ops or Drummer.

Haha, that's a lot of advice for someone who hasn't ridden a bike with any of these pipes on it, much less even heard one, or own a Buell Jordan.

I realize you are trying to help, but try to understand that peoples hard earned money is at stake here, and they come here for advice, assuming that the advice given will be solid.

All I'm saying is that perhaps you should preface such advice my letting others know what your experience with them is.

Andy may be right, but Jraices advice sounded good.
gazooba, I can just tell you my experience with my Drummer and with no mods or tuning has been very good. It does bypass the valve, but I have improved power throughout the full rpm range. If you want numbers and sound clips go to the American Sport Bike exhaust shoot out. It's very good info. I can also tell you that I've dealt with Kevin (drummer) and Odie (special ops) and have nothing but good things to say about both.

You do have that right I have never ridden a buell with an aftermarket setup...

Just stating facts from my research on the American Sport Bike shoot out along with information I have heard from Kevin about the valve and many others about tuning, quality etc...

If you have any issues with my "opinions" being false then you probably have more benefit of the doubt then me but from my research I can say that I am getting a drummer, and was simply stating why I feel its the best way to go.

Regardless they all sound sweet : )

Hey man, don't think I was attacking you. But imagine this: if all the advice you have been given lately was from people that didn't own a Buell and hadn't actually used the products you have been asking about...they were merely regurgitating other peoples opinions, it would make that advice much less credible, no?

All I'm saying is that in general, this ought to be a place where experiences and ones opinions based on those experiences are shared. And if it's not based on that, simply say so: "I don't have a Buell, nor have I heard then in person, but I have done a bunch of research and here is what I have learned..." I greatly respect the experience and opinions of those who have been here a long time, you should too.

An example of misleading info: they do NOT all sound similar (or "close" as you stated)! There are big difference in sound level and quality in all of the pipes- something you need to hear in person to differentiate. Also Jardine does not have quality issues on all of their pipes, and the bracket that had issues has been redesigned and I haven't heard of issues since then (if anyone knows that they have the new style bracket AND it failed- please correct me!). FWIW: I have a stock pipe, a factory race pipe, and a used Spec Ops (sold the Spec Ops to my brother now). I have a buddy with a Jardine carbon fiber, and I have heard the Drummer and D&D pipes at local bike nights. I still don't find myself enough of an expert on them to spout off definitive answers to peoples questions. And I like my race pipe best. : )

Anyway, lots of info out there- use the advice you've been given to start gaining your own experience.

Well put... When I get the buell/drummer in the coming weeks Ill let you guys know how it compares to stock fueling/exhaust ; ).

And I do recall saying the D and D was louder and that they all sounded sweet, not similar but regardless my point is, its a pushrod twin... Put a less restrictive pipe on and whichever you get you will have a grin on your faec : ).

Both Kevin (Drummer) and Odie (Spec Ops)designed their pipes so you can bolt them on with no other tuning NEEDED. The bike will run fine. Of course, a little tuning (even with a bone stock can) will yield slightly better results.

Try not to get caught in the numbers game and get the pipe YOU like.

+1 paint...

But IMO those are the best two to go with, especially if you dont want to mess with fueling.

I am just planning to do the breather reroute and a drummer when I get my XB12Ss... Want to look into further tuning down the road but thats talking years not months.

It sounds like the Drummer or Special OPS are the way to go for me, when that time comes. I'm assuming from what I am seeing here that neither will cause my bike to run lean, even if I do not adjust the fuel, and that was my major concern.
