Hi guys,

going to get rid of the giant vespa exhaust on the Ten and sling on some MTS's.

I would like to keep the balance of the bike and stick a pair on but everything I see so far reckons the single is better for performance.

Not to worried about gaining 0.5 bhp or whatever and want to keep the thing reasonably quiet (but not vespa quiet like it is)

any down sides to the twins ?
