Sorry Vern, but he's right to some extent... The mounting plates for the centrestand take bolts that go into a tube section under the collector box or Y-piece. Trouble is that there are a couple of systems that do away with the centrestand & this is probably one of them. I tried one where the headers go under the sump, so you lose the sumpguard & centrestand & due there being no sumpguard, you also lose the engine bar mounting points for the usual fitments (Touratech/BMW Adv/etc). The only ones that I think still fit, were the Hepco Becker ones. I decided it wasn't worth it...
