In order to achieve the best performance possible from this product. We have designed the layout of this exhaust system to be as straight as possible. By minimizing bends and the angle of the bends, we were able to maximize the exhaust gas flow efficiency.

The conventional style flange is not used to help reduce weight even further. The use of the springs and clamps eliminates the need for gaskets as well.

The long fiber wool threads were adopted for the silencer. This type has proven to last longer than the traditional fiberglass materials even over a longer period of time with extensive high temperature exposure both at high and low pressures.

Only the racing layout muffler design in full Titanium can produce the exhilarating race sound that is second to none.
