Poddy,
The TOR sounds great! I wish I had a clip you, but I've never bothered making one. I've seen clips of the Trident system though, and from what I can tell, they sound very much alike: a nice raspy growl that is absolutely beautiful and unique, nothing else (besides another uncorked Triumph triple of course!) sounds like it. It's definitely louder than stock, but as long as you go easy on the gas, it's not at all objectionable and it won't attract the wrong kind of attention (LEOs). WOT is a different story: it unleashes the hounds, but sounds fantastic! There's also the fact that the TOR looks exactly like the stock can, so if you want to maintain a low profile appearance, it's your best choice, (and for the ultimate Q-ship experience, leave the panniers on). Cosmetically, I think the Trident system beats the TOR severely, but if sound is your main criteria, I think it's a wash, and if price is a factor, the TOR wins. Personally, had it been available when I bought my Sprint, I would have opted for the Trident over the TOR, but that's because I'm love with their looks. That said, I'm still a happy camper and have no regrets.
Cheers! :chug:
