[QUOTE="nobby, post: 32429, member: 257"] Since my racing days I use a stainless Supertrapp with a 2" pipe on the Comet, on the 500 but also on the 600. It is adjustable, you can alter the amount of silence plates, you can also use an open cone at the end. But this will produce a lot of sound... WIth a not silenced Supertrapp, and open cone I once produced 120dB in low revs. For reasons I still do not understand, when going fast on the track there is less sound! There are also lightweight alu versions, those are also shorter. I do not like the looks of those. With the 600 I went with the help of Peter Volkers to the dyno, we fiddled some with jetting and silence plates, and at the end we got 39.8 bhp out of it. The discussion is to be found here : [URL]http://www.vincentownersclub.co.uk/showthread.php?2842-Comet-to-the-dyno-test&highlight=dyno[/URL] The dynoclip was posted to youtube, but I could not find it, maybe I have to upload it again?
