Installed easliy - uses existing screw and bolt locations so no drilling or modifications! Ony issue was a missing part as shipped by aFe, took another week to get it and complete the install. Adds a nice "throaty" sound at higher revs. Small perfromance improvement and will watch mpg. All in all pleased.
