Akrapovic exhaust - 3 versions - differences

[Just_me]

I see there are three different version available for MT-09 at Yamaha webpage but what are the differences?
Is it just a difference in power or do they sound different as well?
Number 1 and 2 looks almost identical and number 3 got this carbon look at the top.

1. Full System with Titanium Muffler

The main difference between 1 and 2 is that system 2 has three fewer assembly joints to leak

1 is original one from Yamaha.
2 is later model with one piece header, as said ^^^^
3 is new type for 2017 bike.

all should fit though.

So the differences lie in the design and they problably sound the same?

Unless you fit the optional cat, which will make it quieter.

The 3rd option does not have a removable baffle, or so it seems. I've just ordered a 2017 MT09 and will be going for option 2.

 

[MT-09]

I have just had confirmation from Yamaha that the new 2017 akro does not have a removable baffle however, they are all the same fitment. so I will be choosing the older version with removable baffle.

Looks about right - the schematic on the Akrapovic website shows there is no removable baffle..... and it's over a grand!!!!! The carbon is, of course, way better looking.

I went for option 2 for my 2016 MT09. Free delivery to Sweden. With removable baffle.
