hello, about two years ago, cut my down pipes of, where they connect to exup valve casing! they were knackered! sent them to Dens Exhausts, they advertise in classic bike mags, £115 later! and stainless down pipes! shaped from original mild steel 3tj pipes!, new S/s headers etc!
When i got them home, got them tig weldeed to the exup value casing! tacked first, then removed from bike, and tig welded, basically the only welding was the 4 downpies to the exup casing, ( its round in shape)
£115 and we never have to look at them again! and they clear up like new, two yrs later!!
hope this helps, no jetting, r6 pipe cutting welding etc!! its another option!! the bends follow the original bends so it fits as it should!
look in any classic bike mag, or if ur stuck, i will try and find the receipt! (tel number) they are based in London, and 100% to deal with!
