From what all the R1 guys say teh Arata is very good BUT if you want power low down you DO NOT want a full system

This is because a full system removes the R1's Exup valve, your R6 does not have an Exup valve so this does not apply to you. A full system is the way to go for the R6

I stand corrected.

What then would be the benefit of full system?

High end power only?

Under normal street conditions, a full system seems like a hard sell given this fact. More money spent for less power in the middle?

What is the significance of the R1's Exup valve is it purely an emissions thing?

So is it correct to assume that removing the exup valve would change the power curves? And if so, why are aftermarket exhaust companies not building full systems that contain new or re-use the existing exup?

So bottom line- for street use, slip on is the way to go???

For any bike?????
