As above the ebay fmic arent the best but they do the job if installed properly.
I will be changing the pipework myself as im not too keen on the ebay stuff and I want to keep the side grills.
I did not cut my crash bar, I drilled it and mounted the fmic to the bottom of it.
Check my bora out on the projects thread its first on the list, bottom picture. That will give you an idea of how it fits.
I am looking out for the R line bora front bumper as I prefer the stealth look too but you have no chance IMO with the ebay stuff.
