just installed a set of cobra quiet baffles in my 1800c with the slashcuts exhaust system, MAN! what diffence! you still have quite the sound but whats eliminated is the BLAT, BLAT , BLAT, sound that comes with the baffles that are installed when you buy the cobras. well worth the 65 bucks that i spend. anybody else have them installed on there vtx? :agree: ?
