ANYBODY HAVE ANY EXPERIENCE WITH THE BIG GUN QUIET SLIP-ON? NEED A SYSTEM THAT IS AT OR UNDER THE 94 db LEVEL (W/NO INTERNAL ENGINE MODS), THE DEEP YZ426 SOUND WOULD BE COOL - DON'T WANT A MINI HARLEY!

I've heard Cobra pipes are real quiet...:D :D :D :D
yeah cobra pipes sure are quiet but their way to powerful for a 400ex. if u want a really quiet pipe i would get one from sparks racing. :D
lol, yep or try D.G. RCM pipe. very, very quiet pipe! lol
