I'm currently undergoing a quad pipe upgrade on my 535d, i'm currently running decat, dpf delete, remap, turbo back ss 3" with single dual tip backbox. i didnt realise i could have gone quad until further investigation but in order to duplicate the original install i need the rear spare wheel boot well removing.
the problem i have is finding someone reputable to do the work. do i cut it out and weld a flat piece in or do i try and suorce the M5 floor pan?? i dont want to spend too much money but want th right job doing. i'm located in manchester so someone local would be great.
any advise welcome!!
