You didn't say what you were going to fit in place of the stock muffler. You weren't suggesting running the bike with an open pipe?I am collecting my new 2016 H2 later today.
Is it AFR safe to remove the ugly stock muffler, or should i wait until i get the full exhaust and ECU re-flash?
Oh Ok if you say so.....it's a bit lean. if i remember correct it was something around 13-13,5 during acceleration and 14-14,5 when cruising. But i also had installed a dna filter when this was measured.
i think that cat is producing more backpressure than any open system so it would be fine without the muffler.
I understand the H2 (not talking about the R) would have been tuned for the stock and the replacement Akro exhaust to work within the parameters of the ECU ( for correct fuel mix ratios etc). And from Brock himself has told me both those exhausts are close to each other for flow and performance hence not needing to be flashed for performance. However when I asked Brock about his Alien head slip on at once he told me the fuel map would have to be modified for that exhaust to work properly.You do no need muffler to provide back pressure.
Disagree? How much back pressure does a h2r have?
Oh excuse me professor Vmax + H2....I happened to be in contact with Brock last week regarding adding to my stock system an Alien head slip on. I asked Brock that same question as in my post, yes if the Alien head slip on would work without a remap? The answer was just as I have posted. No you cannot add the slipon without remapping fuel.With filter aswell you may need fuel but I do not believe that a standard bike with just an alien head slip on "needs" a remap. Are you sure brick was not referring to a full exhaust? If not then I wouldn't comment further as I do not wish to offend a forum sponsor
WoH tuoba I etirw ti sdrawkcab rof uoy...Bikes run like **** without end cans or mufflers in case you haven't noticed. Maybe you should try it and see how your bike performs. We are all grown ups here so if you got something to say, say it...horses huh.....I said I wouldn't want to offend a forum sponsor. Anyone who tells you that a remap is necessary for a slip on may have a horse in that race? Do you understand what I'm trying to say? I could try to write it upside down
