Motad 400-4 pipesets
Chris400F:
I'm sure I read somewhere that aftermarket suppliers will not make double skinned pipes as the tooling involved makes it not cost-effective.
Out of interest, do 'modern' bikes still have double skinned pipes or have manufacturers gone for single skinned?
I think many nowadays are not chromed so 'blueing' (or 'yellowing') maybe not such an issue.
SteveD CB500K0:
The downpipes on my Tiger 800 are a sort of brown colour. They are not chromed.
I suspect that people expect to see shiny chrome pipes on a classic bike, but on a modern bike it doesn't matter.
motad_uk:
the tooling cost to double skin a specific 4-1 is likely to be around £30,000
divide this by sales of (perhaps) a 100 and the cost of a double skinned system against single skinned (and a bit of discolouration) is increased by £300!

I am lucky enough to have a new set of originals but if not I would have gladly paid the extra 300 GBP for double skinned. I can't understand why Yamiya never went for double skinned, as they did on the 750 pipes they repro.

Bottom line is that (probably) 90% of all potential purchasers although they would like the extra feature, have another use for the £300. Its like when we have an option on a particular model and deciding on making (lets say) a 4-2 system or a 4-1 at lower cost- if asked 90% of customers will prefer the 4-2 if it looks more like original- and 95% will actually buy the 4-1 becuase its much cheaper
