Anyone ever tried a tailgunner exhaust on a KZ1000

I have a 2001 KZ1000p I'm thinking of adding one of these two types of exhaust. Any comments or success stories about these??

Well I dont know about performance being enhanced, but it will turn heads.
Never saw the jet engine model before. Maybe I should get one for my turbo exhaust pipe.

Those are cool, they look $$$ though.

You'd better use some difficult to remove hardware(think TORX, or star type fasteners)as somebody will try to remove it for themselves, if not the whole bike.

600.00 plus adapter 110.00 on their website reminds me of OCC stuff kind of cool but a little cheasy
if I had too much money I might try one for a while

I listened to a sound clip and it sounded horrible but that was probably jut the bike it was on
