No- the catalytic converters are located in the collectors of the exhaust pipe, well forward of the muffler.

No, replacing the stock muffler and exhaust pipe will not cause any error codes and <should not> have much, if any, effect on emissions.

Dumb question from a newbie.
Is the Catalytic Converter inside the stock muffler (2014 model)?
If so, does replacing the stock muffler cause emission problems/codes?

So, are they not putting ethanol in your gas over there?

 I recently was able to get some 100% gas on a trip when passing through Oklahoma and I think I could have easily gotten 250 miles from that tank if I was wanting to, but we stopped for lunch and gassed up earlier than needed.

The Germans put "up to" 5% ethanol in the fuel without any indication except a tiny sticker in some pumps. Then they sell the E10 clearly marked, that nobody buys, and it contains "up to" 10% ethanol. Thing is, ethanol contains less energy per volume than good old fuel, so E5 represents an increase of fuel consumption of about 1.5%, and another 1.5% if you put E10.
Let's say E10 is 3% cheaper than pure gas, you spend the same amount of money per km, but more volume of fuel. And the fuel tank in the bike doesn't get bigger, so you have to refuel 3% more often. Doesn't sound much, I know, about 5 miles per tank. But those calculations are made on a family car, not on a high performance engine from a motorcycle.
So, to your question, I always refuel E5, weather I like it or not. There isn't pure fuel anymore over here  :-X

The only reason it would be cheaper is because your tax dollars subsidize it (certainly the case here in the US). So your paying for it even if you don't buy it.

you guys are funny. I have an '08 and have done 250 miles plus on a tank several times, at a leisure pace but not obsessed with the mileage and gunning it as needed.

So, to your question, I always refuel E5, weather I like it or not. There isn't pure fuel anymore over here  :-X

Well if you are getting 250 miles per tank with a 1st gen then that's pretty fantastic mileage. I hadn't heard of very many, if any, Gen I C14s getting that over here. Perhaps I haven't been as attentive of the numbers as I think I have, but it seems most Gen I C14s are getting only high 30s on this side of the pond. 5% difference in ethanol doesn't seem like enough difference to account for that. Is it the O2 sensors?

You're in luck.  The only good exhaust video in existence on the internet uses the Two Brothers on the C14
