Exhaust, filthy sods!
Pikes peak looming fast and as I'm having to resort back to the 400 it has a full arrows race system, not the quietest.
Only the forward half has packing, rearward just a cage with the end cap.
Bought more packing (on a roll instead of candyfloss type)
Someone mentioned DB Dawg but can only see them for sale in the US.
Sensible suggestions (sexual favours and backhanders to Noise testers not allowed)
