General topics » Exhaust: Euro4 vs Euro5

If the 1200 had euro4 and the 1250 has euro5 but the OEM exhaust looks exactly the same, what is different?

I see on the only replacement exhaust so far from Akrapovic is different in that for the 1200 there is one exhaust hole and on the 1250 there are two. Are the mounting locations different? Why do none of the 1200 replacement exhausts fit directly on the 1250?

Speed Pro Cobra in Germany make a stunning carbon sleeved exhaust both EU compliant and homologated for the 1250RS.

I've fitted one[ it's throaty, looks good and pops like crazy and imaginably? seems to make the bike go faster and matches the Ilmberger hugger.

It has a removable baffle which when unfitted produces 95db at idle and 100db at 5K. revs. Baffle in produces a road legal 85db rising to 90db at 5k.

The model is the GTX-O slip on GX1- 7683-348 at www.speedpro.de

Are you just taking about the end can because the 1250 exhaust has an extra lambda sensor installed after the catalyst.

Hi Bunter,

I measured the sound one metre away from the end. The baffle is within the link pipe.

Don't know about the sensor but my dance teacher threw me out of his Latin class.

The area where other manufacturers more obviously cater for Euro 5 is in the catalytic converter (some bikes having 2 or even 3 separate ones). I suspect that the major change might be hidden there and greater resistance to flow might result.

I'm pretty sure that 1200 exhauts do fit a 1250. Looks like I'll be the 'brave' one as I'll be ordering a 1200 SC Project exhaust for my 1250 when if finaally turns up

The R1200RS is certified for EUR4 as the R1250RS meets EUR5 requirements. So they are both EUR4.

And I use my R1200RS EUR4 Bos exhaust on my R1250RS wihout any problems.

I was talking to my Remus rep and he mentioned they are coming out with an exhaust for the RS soon as well. What are anyones thoughts on Remus?

I read somewhere the Euro 5 exhaust silencer is 1 litre larger, to allow for more silencing material.
