How about the Leo Vince?
Two brothers and Akraprovic are not that hot.
The ECU upgrade on the Termi's isn't a "must have" but if you can afford it, I'd spring for it. If your gonna be running a DOT regulation slip-on, not the racing version, you don't really need that ECU upgrade, your only gain would be sound. If your gonna run the track/racing non-DOT legal version, then I'd spring for the ECU because you'll see some gains in power, all be it very slight. The biggest difference on the 848 is the FULL kit, which increases the diameter of the exhaust system AND removes the flapper valve.
