Exhaust Part ID- Pictures

[Sherlock]

Can anyone tell me what this is and/or what it does?

[He Man]

its an an exhaust pipe. it redirects exhaust gasses to the rear.

I guess I walked into that one. Let me clarify. The rectangular piece of steel with the hex nut is the part that I was referring to specifically. This is on a 2007 S2R with stock cans. Don't know if this was a mod from PO or what. Curiously, the words "not for highway service" is stamped on the back of this piece.

O2 sensor plug?

[He Man]

whats on the other side of the hex?

Its used to hold those pieces togther so they dont move and you can get a better fit for your exahust cans. But why theres a hex there is beyond me. Perhaps its 2 tabs that they welded and installed a system onto, then bolted the 2 tabs together and welded it.

[Sherlock]

whats on the other side of the hex?

Here is the other side. Oh, and it says "Not For Highway Use" instead of "service", if one wanted to be specific.

[He Man]

from that angle it looks pretty thick. Is there a cross over on the bike?

Tap it does it sound hollow?

have u tried removing the nut?
It could be something to stick a diagnotistic tool in, and serve as a cross over, and also to structurally hold the 2 pipes togtheer

looks like a QD midpipe replacing the udder with a crossover with an O2 bung plugged with a bolt.

Sorry, I drilled down to the Motowheels part, there was a nice pic of the part for the S3R800 and I snagged the url - sorry

but it is the Quat-D midpipe for the S2R

[Sherlock]

Thanks. So I'm guessing the PO either had custom exhaust that he obviously wasn't willing to part with, or he just wanted to eliminate the udder. Either way, I still think it's funny that it says "Not For Highway Use" on it.

I had a Quat-D midpipe on my S4Rs (still have it is anyone is interested).  I think most non-factory exhaust systems/parts say that.  A legal thing probably.  Just don't ride on the highway - keep it in the city and you'll be fine.  (j/k)

[Raux]

since it doesnt have the Cat.. it's... for offroad use only.

[Sherlock]

thanks!
