i recently purchased the exhaust and the instructions are pretty clear, but when looking thru them, its was stated that only models 2006-2007 for the suzuki m109r needed a dyno jet or power commander added to it. I currently have the 2008 suzuki m109r and it did stat that i needed to put one one. Is this correct, please help me with this one. And do i really need one. I was only looking for sound not actually trying to beef up the performance.

 

If there is not any suggestion or the advice on putting the next one so I think you probebly should not do this as It is not need in the model so just keep it as it is and enjoy you default one.
