Nope, the US-spec two-into-two system won't fit on the left-hand side. That's £100 up the Swannee. What's interesting is that Suzuki have welded the pillion peg brackets onto the loops that carry them. The pillion peg brackets actually have holes in them for a bolt to pass through, but as they're welded directly to the frame loops, they're useless. HoHum. I'll have to buy a 2-1 system from Wemoto, then. That leaves me with a brace of header-silencers that probably won't fit anything this side of the Atlantic. I'll keep 'em, though, because "they might come in handy". If nothing else, there's a pair of nice silencers there that could be chopped off and bolting onto something else one day.
