Mid pipe question

[The Bearded Duc]

If one were looking to drop the oh so beautiful udder on a 2006 S2R 800 by adding a Marving or Spark mid pipe would they also need to reflash the ECU?

And, while doing that, would it also make sense to open the airbox?

Anything else I may be missing? Maybe a Power Commander?

Midpipes only won't require a reflash.

Do you have slip ons already?

The slip ons - midpipes - open air box - open'er filter combo requires a reflash.
With the DP ECU, this combo gave my S2R 3 bhp and 8 Nm more than stock.

I just did the Marvin midpipe on my 08 s2r. I did however also do the ECU, and pod filters.  Which all in all was not cheap. The end product is awesome. I notice no lack of performance with the pods which others say they do. My guess is that they are professional racers and can tell the difference of 1hp at 120mph. Rule of thumb is that you can play with the exhaust , but if you play with the intake, then you will need to alter the ecu . Oh yeah, if you decide to get the pods, beware. At about 6k, she opens up and sounds like a tornado. Freak'n awesome.

I do have a slip on. I have the shorty Termi set up.

I doubt I'll go the pod route. I really don't like when that space is completely "see through". I know I'll be tarred and feathered for that but...

I'll probably just end up cutting the airbox and dropping in a K&N filter.

I don't know how the shorty works, but it is quite different from two larger slip on cans.

Maybe you can do the midpipe, cut box and filter - test ride it and have the exhaust sniffed (don't remember what it's called when they do that). If it doesn't run smooth and/or runs lean, then get the reflash....

I'd sooner keep the udder than fit a Spark or Marving midpipe. They look way gimpy. Check out a Quat-D instead, sold at Motowheels.

Better yet go for a full Arrow system. No ECU mod required if you're just going with an exhaust, but as others may have stated if you open the airbox as well you have crossed the Rubicon and will need to get the ECU reprogrammed to add more fuel to go with the increase in airflow. It's a simple concept to grasp.

Power Commanders are not as good as getting a DP map programmed into the ECU. They are a piggyback add-on and thusly there is a slight delay in signal pulse. I'm not saying they aren't good for fine tuning the fuel delivery, but they should go on after a proper DP ECU.

Of course, you will want to ensure proper valve clearance and throttle body sync before you do anything. And with a Power Commander, you will need a proper dyno tune at the end of it all to make sure you get your money's worth. The canned maps on the website are inadequate as every individual bike will achieve optimum tune at different parameters.

How does the Marving or Spark look gimpy? The diameter of the mid pipe can't be any smaller than the stock pipe, can it? Are there any other companies that offer just a mid pipe?

Wouldn't the Quat-D have the same ground/lean clearance issues as the stock udder? Besides, I'm not sure I wanna change the exhaust. I kinda like the short Termi.

I have the 6k service coming up so I'm not worried about valves and TB sync.

that's a Quat-D

It's just cleaner looking as a result of its crossover design. It allows the pipes from each cylinder head to follow a more linear line back and remain parallel without forcing them to meet underneath the swingarm pivot. It connects the pipes via a hollow box chamber. To my eye the others don't look as tidy.

Ahhh, I see. Every time someone says Quat-D I think their Ex Box exhaust.

I do like the way that looks but motowheels doesn't have it listed anymore. Do you know where else I might be able to get it?
I checked their website but my Italian isn't so good.

Might be that it's become unobtainium. Crazy since they sold it on their website for years. That's where I bought mine.

If you wish to pursue the matter the guys at Motowheels will answer your emails. I'm sure you could get one if you tried hard enough.

That said, it's my old S2R800 you see in the photo. I bought the Termi slipon kit, but later sold the mufflers because I didn't like the look. Too damned long in my opinion, they went way past the tail and that's a no-no. If it looks in any way lame or gimpy or out of proportion I cannot stand it. Sounded great though. I kept the DP ECU and airbox/filter, and just cored and packed my stock mufflers, polished the tips & inlets, painted the cans with hi-temp, and had the rest ceramic coated at Jet-Hot. I noticed zero difference in sound or power than with the Termi carbon mufflers in place. However, the bike looked more cohesive.

Thanks berg, I'll fire off an email to them.

I've always loved your bike, I was a little upset when you sold it. I'm the same way when it comes to lines and symmetry, those termi cans are way too long!

Here's a link for you, might help answer the fuelling question.

I had the opportunity to ride standard and modded, which mine is.
The difference is noticeable.
Cheers.

Thanks for the link.   
I'm not quite sure how far I want to go or need to go for performance, afterall it is only an 800. There are huge differences in HP and torque outputs between a stock set up and a complete "airbox to exhaust" set up, but as sacrilegious as this comment is, I'm not really looking to create a HP monster.  I want to get rid of the udder mostly for aesthetics.

Perhaps I'll want to open it up a bit more down the road but for now I'm pretty pleased. I was more interested in whether or not I needed to do anything else if I wanted to just change out the mid pipe.
