Marving vs Sparks midpipes

[doulos]

+3 or is it 4, for the Spark midpipe.  Love the fit, finish, sound, install and quality.
PAV: no problems, no changes needed to add a midpipe to your bike.
According to my mechanic the S2R 800's have plenty of adjustment range, w/o an ECU change.

If i were to do it again i would purchase the Marving. Shown above is the Spark and in my opinion it hangs too low, meaning, look at the gap between the engine and the horizontal pipe. I was told this is normal, the Marving seems to fit closer to the engine, which i like. Don't get me wrong, the Spark had NO fitment problems and went in without any cussing.

I have the spark mid-pipe also.  I also noticed it seems to hang a bit low, but with a bellypan, it's not as noticeable.

Can’t say enough about Spark’s fit & finish. 10K on mine and still get compliments from fellow Ducatistas.  Worth the wait & extra cash IMO.

I have an S2r 800 and really want to get rid of the udder. Some poeple have said that replacing it with a mid pipe will cause the bike to run too lean and that a Power Commander will be needed to properly adjust the mix. Have others here found this to be true? I hate the udder and would take it off in a sec but i'm getting conflicting info which has caused me to hesitate. Any ideas? 

Well, I bought my Termis and DP midpipes without any ECU upgrade from Ducati.  It was about $400 cheaper then the full set with ECU.  I don't know much about it, but I know that the system with ECU and the system without ECU are on consecutive pages on the DP catalog (the parts guy and I were going back and forth).  As far as I know, they didn't have to make any mixture adjustments.  I didn't expect many HP's.  I wanted the looks and sound.  Couldn't tell you about the power gain because I also had a 14t front sprocket installed and the bike rode completely different.  In my opinion, they are one of the best looking set of midpipes.  They also replace the headers as well as the mids and udder.  They bolt up to the motor.  Here is what the midpipes look like.

Thanks to everyone for their input.

Hey, that's my line 

[q monster]

go for sparks - got mine at desmoworks. best online price for me in australia. but add the DP ECU, open airbox and retune!

Does the Marving pipe interfere with the oil filter on an S2R 1000?

I don't think that either have clearance issues with the oil filter.

While you may or may not have any issues related to fueling when you start to open up your intake or exhaust system, be prepared to have them. The monsters run lean out of the box and opening up the exhaust exacerbates it. There is a Closed-Loop sticky in the Accessories and Mods section that is good reading for any owner of a Closed-Loop Monster, but is a must read (IMO) for owners messing with exhaust.

The short version is you don't have to solve the problem yourself as a FatDuc O2 manipulator makes all the lean condition go away for only $80. Hell, a bike without mods would run better with one installed.

They both have crossovers - says so on MonsterParts website. Some models with, and some without provision for O2 sensors.
I have the Spark on my S2R800 '07 and I'm more than happy, much more. I got them to get rid of the udder, for looks only. People told me not to expect any improvement in sound or performance - they were VERY wrong about sound, and they might have been wrong about performance also. If my sound with open airbox/ECU/Termi cans was a 6 - then the sound with the midpipes is an 8. I guess S4R with the full system is 10.

My dealer installed mine. He usually installs the Termi pipes, but he said he never put on any brand of pipes so fast and with NO issues. No problems fitting them and no leaks - on his first attempt - usually takes some trial and error to get it right. He adjusted the bike to run a little richer, I think that means it flows more air - maybe therefore a performance gain (not always so, but in my case it seems to be more willing to be flogged)

When I did my research, I wasn't able to find any important differences between the two brands. I chose Sparks for price and availability, never regretted it.

And yes, I got mine from MonsterParts

FYI, Richer means more fuel, leaner means too much air

FYI, Richer means more fuel, leaner means too much air

Yes, I know. That is my understanding as well.
 
What I was trying to say (English is my second language) was that since more fuel (richer) was required, it would have to mean that with midpipes the systems flows more air. Before and after considerations.

I hope You and I corrected any misunderstandings - thanks for helping

[trpletme]

How about the oil drain plug? I know.. Dumb ? Great pics of the Sparks mid.  Thanks!

[rockaduc]

Dunno about the other brands, (i would imagine they are similar) but the DP mid-pipes allow you to access everything w/o too much of a problem.

Yes, I know. That is my understanding as well.

This is the spark mid-pipe on my S2R1000, and there aren't any clearance problems. 

[trpletme]

Great pic! Pipe looks great also. Thanks.
