Check out our hand-made-in-the-USA full exhaust system for the 2006-08 Yamaha FZ1. This high performance exhaust system features stainless steel head pipes, billet aluminum flanges and a Carbon Fiber silencer.

Features of the new Tapered Conical Silencer

Inlet: Titanium is deep drawn over a precision die. The inlet allows for a very compact silencer design.

"Ever-Last" Packing (patent pending): Our packing material is made up of several continuous strands of fiber rather than short chopped sections of fiber. Each continuous strand of fiber is several hundred feet long thus preventing it from being blown out of the silencer by the exhaust pulse. As such we do not have to use a stainless wool or stainless steel mesh to hold the packing back. By removing this barrier the packing can do a better job of absorbing the exhaust pulses.

Packing Divider Plate (patent pending): Exhaust pulses tend to push the packing toward the exit of the silencer reducing performance and increases the harshness of the exhaust note. The packing divider plate ensures the "Ever-Last" packing material stays put in the first third of the silencer where it is needed the most.

Tapered Core: The tapered cores are altered in size and taper length for each motorcycle. By doing so we can maximize the performance of the exhaust system on each motorcycle.
