Belter is right about the pics, they're not Termi's. Easiest way to tell is the rivet bands, on Termis they're just a stainless strip pressed with oval cut outs between the rivet holes, on the bike in the pic the rivet bands roll over the edge of the carbon for a nicer finish. The Termis have a nice rounded edge on the stainless flare that butts up against the edge of the C/F.
The outlets on those is too nice as well, Termis have a plain outlet with a rolled edge.
Almost all the Termi slip on's had a pressed alloy bracket that bolted to a steel inner skin through holes in the C/F, straps were usually supplied on full systems where the C/F tubes are thicker with no internal brackets to keep weight down.
Sorry mate, not to say they're not nice pipes, but i'm pretty sure they're Gia.co.Moto who supplied most of the DP stuff.
And i like SilMotor, and Arrow, although they get loud very quickly, the Gia.Co.Moto stuff is nice too, Termignoni and Akropovic are on another level though, for different reasons, the Akro stuff is gorgeous, very nicely made, perfect fit and a nice deep note.
The Termignoni race systems in my experience make good power and internally (where it really matters) are flawless, the exterior is raw, purposeful but often the fit is atrocious, I have a full 70mm on my R which is an acceptable fit and i also have a 50mm "Daytona" Spaghetti system on my 888, OMG! what a bastard of a thing to fit that was! but inside it's amazing, seperated primaries for each exhaust valve all the way to the collector and all the internal welds are ground smooth, when new the internal edges were sharp enough to cut my thumb because i was stupid enough to feel them.
