Performance:
On development using the in-house Dyno we achieved a horsepower increase of 6 with the increase right through the range. Torque was increased at the right spots and there are significant gains right from the bottom through the mid-range. On the road is where the gains are truly appreciated. The throttle response through mid-range is instant and smooth and feels like a lot more then a 6Hp increase. Throttle roll on is also smooth and responsive and has removed any hesitation for the big twin to open up.

Noise Emissions:

Restrictors In: 82dba @ 3625 rpm
Restrictors Out: 89dba @ 3625 rpm

Weight savings:
The Staintune is 3Kg's lighter then the cumbersome original muffler.

Finish:
The system is a single oval slip-on. The system has the unique Staintune removable restrictor system, which delivers a nice throaty fat note, and the system is ADR Compliant and is finished in the world famous Staintune Mirror Finish.
