DSS replica downpipes
matthewmosse:
Well in need of a bit of tlc? Back when I first started on bikes, my mate worked out his dt50 exhaust was restricted and made up a replacement out of sheet steel working out the shapes needed to get a approximate curve and cones to get a working expansion chamber, it remarkably increased speed by over 50% I reacon that for pipes that cannot be replicated economically using tooling and presses, then freehand metalworking might render acceptable results. With a bit of practice and a lot of patience. The cb500/4 exhausts are about the hardest shape, compared to these the 550k3 are simples. Mind you I suspect to pay the tinbasher a decent wage the cost could be high, and the stamped numbers would present considerable problems.

We are the manufacturer of the replica 400-4 downpipes sold by David Silver.
There has been a fitting problem related to recent production- we are in the final stages of updating manufacturing jigs and making some minor changes to ensure that this is resolved and the "normal" fitting process is resumed. This has involved working on a bike as clearances (even with the original system) has always been very close
We are working hard to make sure that David Silver can resume supply of the latest (no problems!) production very shortly
apologies to anyone that has struggled with this recent stock- sorry !!!!!!!

I got mine from Wemoto and had the same problems - not quite lining up etc. To be fair to Wemoto, after a couple of photos were email, the pipes were collected and replaced in double quick time.
Makes you wonder if they all come from the same supplier...
David Silver is the only distributor of our replica pipes- we do not supply anyone else

Look forward to D.S. getting downpipes back in stock. :) :)
I notice that Wemoto don't list 400/4 downpipes anymore.
Kenny.
