"Used for decoration" how!? the F"n thing is INSIDE the dam tail pipe! They think everyone else is just 'stoopid' ..irks me. That's ridiculous, the sound is ghey, it's not even a performance sound, it's just ...ghey. <sigh> oh boy I can't wait for those thingys to hit the shops around here.. big tonka toy cars with "wooing" exhausts..
