Has anyone experienced the difference, if any, between aftermarket headers and modified standard headers? Before my current career I was a sheet metal fabricator and welder (tin basher!) for many years so would be able to decat my original headers easy enough and save myself a load of cash, but would the result be as good as something like the GPR headers (£310) that could be sold on later and I would be able to return my bike to standard?
Cheers.
