Why choose Quill GP1?....

You asked and we listened. Meet one of the 'new kids'. Based on Valentino Rossi's 2007 GP bike, it has the hallmark of a pure race thoroughbred running through its core. And, of course, it comes with a road legal baffle.

The GP1 is born from our extensive research and development program. This new impressive, modern 'mini' can has got the heart of a lion.

With our advanced Dyno facilities, we develop our silencers, not just to give you the sound, but also the power throughout the RPM range, giving you greater throttle response and improved performance even at mid-range.

As with all the Quill exhaust silencers, the GP1 is traditionally built by hand. The GP1 is available as round and is only available in full titanium, which makes it extremely lightweight.

Dimensions are: Body length - 260mm, bore is 50mm and it comes in at 698grams. Only available on certain models.

The GP1 comes complete (hidden hanger bracket), link pipe and clamps as necessary. If the original equipment is a pair, then we will supply you with a pair.

We go to the ends of the Earth to bring you the finest quality, we don't compromise - Why should you?
