    Quick Duplex Exhaust System help please.....

    Some quick help needed....

    I'm having a custom Turbo back duplex exhaust made for my Zaf GSi but am unsure of the dia of pipe to go for and what boxes to use for the loudness.

    The guy making it has been recommended to use 2 1/2" pipe with a 20"x5" centre box and 2 12"x5" rear boxes either side

    I want a nice sound to it but not a harsh rasp and no hold on performance.....

    any recommendations???

    2 1/2 inch bore is fine, thats the same as the Milltek exhaust. Not sure on silencer sizing though and of course, the tailpipe style is down to your preference.
