I have the quad pipe, rear exit Librands system fitted on my Series 1 Aero.
I had smaller S/S side boxes (under the running boards) made up locally as the older, larger ones caught on e.g. speed humps, etc.
These have cured the
'grounding' problem and as a bonus, have produced a deeper
'growl' to the soundtrack and
may have added a little oomph to the performance
I also designed and fitted an aluminium, powder coated diffuser to the rear to fill in that (to my eyes
) odd gap -
(Apologies to those that have seen this photo before !)James
