There are cheap alternatives around, (especially if you have a garage full of old Brit bits) but it takes about 10 minutes to do the baffles, costs nothing and maintains the internal structure of the exhaust that was tuned for it. Underway the sound reminds me of the RE Interceptor (minus the thrashing tappets), especially when opened up in 4th up a steep hill. Part of the problem with fitting mufflers is the crossover pipe; it really needs another section welded in past the crossover to take the new mufflers and that means some chroming if you want it to look neat. I had a look at putting some late 60's Triumph mufflers on, but in the end the baffle job sounds good and doesn't take any messing about to do. Apart from the effect on torque from removing the crossover, we have an O2 sensor on the crossovers here and disconnecting it throws up an EFI error. A full system like the Staintune is around $AUS1800 but to my ear they sound awful; very blatty and harsh. There's a very good sounding Japanese stainless set for the 650 which fits - cant remember the name but I think it starts with a "D"; it is also pretty pricey. A set of standard 90's-current Sportster mufflers could be fitted easily enough after the crossover, and they sound nice too.
