.... next plans brabus backbox.....
If you haven't yet got one, then don't waste your money on the Brabus one....
as has been stated before...it's made of mild steel, not stainless...so it rusts.
It weighs a ton....and new it costs well over £500 ! !
For that money you can have a full custom system made up....from the manifold back.
Or....if your existing system is ok and you just want to release some of the back pressure
the standard back box creates, then look out for a Remus stainless steel one...which is a
straight fit and costs about £350 or so.
With the CDI, don't expect a growl or roar if you fit either the Brab or Remus...in fact it
won't sound much louder or throatier than the original ! I had a Remus at one time...
which is how I know about it. (and it took all of 10 mins to fit after removing the old original)
