Mapping was supposed to be today but I've asked Mark to delay it until tomorrow so that these can arrive
Not the prettiest thing in the world but it should reduce the noise considerably so that I'm track legal - there's not much else we can do to make this system quieter so this is the best and probably only option
Whilst they promote a "straight through flow" design, it will still affect the back pressure ever so slightly, so it's worth sticking these on and getting Mark to produce a "track" map for me
