I had the Miltek Mk.2 full system,
boooooom-tastic, made worse with 100 cell cats.
I now run standard system (and standard cats) with SS Race Lightweight backbox - it amplifies the CSL 'rasp' nicely and is rather less droney than my old Miltek.
Also looks better too imho, and passes noise testing with 97db at most places i have been - except Oulton where it was 101db?!
