To achieve what exactly?

[nightrider]

Had a power commander fitted to mine ,pipe and kn filter ,then dyno run to suit ,  it goes quick anough now for a 305 kg bike , that's made for touring , if I wanted more power then I. Would buy the zzr1400 ,,

Because I like tinkering

Currently my 2014 GTR1400 has the SISF Mountain Runner flash.Bike is stock standard in terms of exhaust and air filter.
Power/torque from 1500rpm up.
Low down torque and mid range torque is out standing,fuel economy has increased from 5.5ltrs per 100kms. to 4.8ltrs per 100kms that close to ECO mode its not funny.
Engine doesn't have to revved to around 4000rpm to achieve outstanding acceleration now.
Powers up steep hills/mountains easily in a gear or 2 higher due to the increased torque.
Great deceleration on throttle back off.
Smooth gear changes with out drive line snatch even when going on and off throttle.

Cut it out then reweld.Although i think the zx headers have larger downpipes.

No No No .... my GTR was lovely just as it was when it came out of the crate

My GTR's must have been blessed because their performance was more than adequate and certainly met if not exceeded my expectations as a standard bike. I must confess though I did have an aftermarket top box plate on my second GTR.

The cats can be removed from a 16/17 GTR, some work required but it can be done. Soooo much smoother with them removed.
