I'm in the process of swapping my shock at the mo but have not done this mod as yet. Can I drill through my airbox before the whole process so, sort of, creating this mod in reverse order so to speak? I'm guessing Yammy just expect us to take the whole exhaust off every time this job needs doing right? This is madness, I have no knuckles left and all my neighbours have the right hump with my language :0/

Will most DIY stores sell a suitable gromet/plug type thing? Screwfix, Homebase etc?

Any guidance gratefully received.
