specific model built specifically to keep the usual attacks to Raptor series, to also be installed even for those who are beginners!
Time for installation 5-10 minutes ca.
To be used only in competition.
THE NEWS 'compared to all other drains on the market is that included in the package is a "cap" system that allows you to change the tone and type of actual yield (up to three) thanks to a hexagonal screw. (20 Sec. To do this)
Used with "closed system" the sound takes on a much more I suffer and gloomy sound and the noise level is very similar to the original.
They are included in the package a new clamp in steel and assembly instructions.
The sound you are hearing is reportedly just the discharge of a Raptor 660 with our final!
Notes in the order you need to specify whether it is the 660R version from 2000 to 2005 or from 2005 to 2011 version of the 700r or 700r until 2016
