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.
 
 RACING LAYOUT
For the best exhaust efficiency results minimal bends and curves was the design focus points on this product which aided with the supreme results.
 
 EXPREME Ti TESTAMENT
