Wanted Downpipes

[fazerboy01]

First time I had my pipes off I tried the WD40 for a week, and sheared 3 off of the header nuts. Lucky a pal was on hand with a mig welder  :'( . Next time, I lobbed them up with copper slip on the header bolts at time of refitment, then when I needed them off 18 months later, I coated repeatedly and alternitivly with GT85 and aerosol PlusGas, no snappages and this has worked another 4 times. Just what each individual prefers.
