I don't really have any new information for you, but I can give an opinion. For sound alone, the TORs for the roadster were a nice upgrade. I went from barely hearing my exhaust (really disappointing) to enjoying a nice low purr that opened up pretty well around 3000 rpm. I didn't notice much power improvement with the slip-ons and the triumph tune, but I never got it on a dyno. If you want to try the TORs but don't want to blow your whole budget, I'm trying to sell mine (got a Reband pipe from those crazy Aussies, and I'm not looking to go back). Shipping costs may be prohibitive, though. Best bet is probably to buy new from your dealer, if you can!
