OK-

I just did my first service- so I had my belly pan of the beast off.

I looked the link pipe over and found this part number: L-B10CE3
They relates to a 2010 S1000rr Evo Street exhaust.

So... the corresponding Evo link pipe without the cat is: L-B10E1

The L-B10E1 fits the HP4. I have mine ordered, should be here mid next week. I am going to weigh them both and post numbers. But as far as fitment is concerned it's the correct PN.

Something about the weight savings don't quite add up. On the Akrapovic website...

1) The weight listed for the full Evolution exhaust system w/cat is 11.2 lbs.
S-B10E1C-HRC Evolution Line (Carbon) - Akrapovi

2) The weight listed for the full Evolution exhaust system w/o cat is 9.3 lbs.
S-B10E1-RC Evolution Line (Carbon) - Akrapovi

So according to Akrapovic, it's only 1.9 lbs weight reduction. So has anyone actually weighed the exhaust to verify?

we have weighed the link pipe and the cat pipe on the HP4 , the link pipe is 1.110 kg lighter then the cat set up with the akra carbon fibre badges and carbon cover on the servo motors

we got a 3.29 hp increase with the connector pipe on without testing with the PC 5 ,

we could not test the PC5 as the lambda sensors on the HP4 headers have 2 small inlets instead on one like the normal Akra evo pipe

What was the Final HP #? Did you get a increase every where?

So just slightly less than 2.5 lbs, I thought 12 lbs seemed off especially when the Akrapovic specs listed the total weight at 11.2 lbs. According to weight specs from Akrapovic, there is no difference between the Cf muffler sleave and the Ti muffler sleave.

I got my numbers wrong apparently, was told reduces 10-12 lbs with all the flapper valve peripheral. The more I think about it, it seems to be way too much. 2.5 lbs still sounds low, but it's still a reduction.

Can someone just confirm after they install the mid Pipe, That I will delete the Cat pipe(Fitmet is correct for part # L-B10E1) I take it you will have to disconnect the Servo Cable on Front and Back or just Rear pipe? and you would have to block pair valves, with block off plates. Will the Stock ECU be ok for this mod, without a piggyback fuel type management type system? Bazz or Power Comm.
