pd160 intake is ample..with green panel or equivialnt its a good improvement...
i have full turbo-back milltek exhaust...best sound ever!
They don't actually do a full turbo-back for the PD100 so have been in touch with Milltek through JKM to see if the one for the PD130/160 will fit, they don't see any reason why not but don't know of anyone who has already done it so gonna order one and hope for the best... May be the first PD100 running it (as far as Milltek is aware anyway)...
