Another Shorty on a Fazer (exhaust that is)

Same sort of exhaust by the looks of things.


It'll sound totally different, but according to my Dyno mechanic you'll never beat the original stock exhaust for best performance.
I just don't like the sound of them, they're a bit too quiet for me.

True - the factory stock setup, all components are put together to operate in harmony.
Anything swapped out from that "safe" configuration, can have knock on effects.

When you say best performance, by deviating from the stock silencer, do you mean efficiency (fuel consumption - mpg) / or acceleration (performance)? A more free flowing exhaust still has benefits?

Car engines are usually "restricted" from factory, to suit the majority of the buying public. Restricted via their firmware/software maps (ECU). People remap them, to get a bit more performance out of the engine (which can actually also increase mpg).

We don't have any equivalent capabilities with the Fazer?

I suppose my main reasons for this change, was the increased noise (more road presence = SAFETY) plus cosmetics to compliment the Naked styling, losing that big long 1/2 metre cylinder for a much more sporty, compact unit. I'm not maintaining this bike to look like it just rolled off the production line.

factory ecu setup has lots of restrictions they have to adhere too and a remap can increase mpg but it will not comply to the other regulations (probably emmisions) after a remap - car manufacturers use mpg as a major selling point nowadays so they wouldnt give less mpg without a good reason (unless there is a global conspiracy by the CIA, NSA and MI-5 which edward snowden forgot to tell us about)


dont get me wrong i love remaps though, stock vw t4 2.5tdi 102bhp VS pendle performance remap 135bhp 250ft.lbs  (just dont tell MI-5)
