Jardines for Valks?

Anyone have any experience with these pipes?

I have had the Jardine tapered style exhaust for 15k miles and have had no trouble with them other than some minor blueing. Never had them dynoed but there is no apparent discrepency between them and any other brand when it comes to rolling on the throttle. I've run with some big boys and I haven't been left behind yet other than of course the blown valks. One thing I am not crazy about is their short length because it puts the exhaust noise just under the passengers ears which can get bothersome on a longer trip. As well as detract from the stereo sound at speed. However, they do get a lot of compliments on appearence and they idle relatively quiet. Hope this helps...Naples Richard

Have you seen any sample sound files on the net anywhere?

Haven't come across a sound bite....
