I think BMW did it on purpose to push people into upgrading to Akrapovic.
This is hard to go wrong with any of these. Just a matter of preference I think. I have had a Akra on mine, now a 2 Brothers. Very similar despite cost difference.
Who's brave enough to pull the trigger on one of these?
Hmm... I'm having a really tough time installing mine. The tailpipe that came with this Yosh is extremely tight and and only a little bit of it fits over the stock header pipe. This tailpipe doesn't slip anywhere as far as the stock tailpipe did, as can be seen in the photo. No amount of wiggling/twisting will help. Is this normal? Did I get an ill-fitting tailpipe? Should I contact Yosh for a different tailpipe?
The whole exhaust sits further back as a result...
So, only about 600 miles on this exhaust, and one of the rivets holding the Yoshimura placard has already fallen off and there is some greasy stuff oozing out of that hole whenever I ride.
I think I should have just spent a little more and gotten an Akrapovic. Live and learn, I guess.
I'll have to check mine.. So far so good I think though.
Yep. nothing missing or falling off on mine so far. About 1300 miles on mine so far, but mostly pavement.
Yoshimura is sending me a new badge and rivets. Now I just have to figure out how to take out the remaining one rivet (drill through?) and install the new ones. I guess I'll have to buy a rivet gun.
Drill through with a slightly undersized bit and it will come right out
I wonder how the mpg is effected with the replacement exhaust?
I would appreciate if you can add if you see increase or decrease at your gas consumption after the replacement.
I haven't noticed a change with the Yoshimura.
I seem to have lost a few MPG after installing the Yoshimura (running it with the silencer in place); however, the exhaust was installed right around the same time as my 600 mile service when the dealer used 15w-50 oil. I believe they come with 10w-40 from the factory. So at this point I don't know whether it was the heavier oil or the exhaust or both that affected my fuel economy. Anyway, we're talking 3-4% drop at most - hardly significant.
Reading your post I figured I should comment again. I don't track my mileage closely enough that I would notice a 3-4% drop. 10% I might have noticed, but I know it wasn't that high. Just wanted to throw that out there since Pete keeps track of it more closely than I do so you _may_ see a single digit drop that I just didn't notice since I don't pay attention.
