4" S/Steel Slip on tips for F10/F13

[S800VXR]

Will get pictures up in the next week or so but is anyone interested in a set of 4" dia tips which clamp onto the OEM exhaust after tapping off the stock tips. I am having the centres offset slightly so the tips do not overlap and they will be held secure with a hidden clamp bolt. Can easily be removed for servicing and warrantee work in case BMW tries to invalidate things because your cars modded!
