just get a custom suitcase delete made for the r32 bumper. my mate had one done for just under £100.
Yeah my exhaust shop said £90 for me as ive used them for a bit. Just running through my head if i could get a slightly more professional sound, althought it doesnt sound bad with the suitcase delete.
Nige as BCS said he could hook me up with a R32 back box, might just be out of my price range - Saving for my re-map
