Save yourself some cash here, just have the milltek back box chopped out and replaced with a louder one :)

Was thinking of it mate but I don't know how it would sound. Also will there be ant difference in performance with no back box? Will the back pressure change?

Forgot to update... Last month I got my centre silencer removed and now my boc Ives out loads of DSG farts :) best pound for pound mod so far!
