csl backbox

i have for sale my d's developments back box,this is nearly a year old,when i bought this the car still had standard cat's & centre section & it sounded fantastic,but i have now changed to 100 cell cat's & supersprint unsilenced centre section & it was to loud for me, so i have changed to the quieter milltek back box. £230 including p/p (will also fit e46 M3)

pic of it when it was new,as you can see it is very well made.
