Got there in the end Wissam! BTW in answer to the question in your OP, yes, the 'drone damper' should be swapped across from your original muffler to the P/E one. Recently bought a P/E and the dealer kindly copied me the BMW fitting instructions which mentions swapping it over...
BTW the P/E doesn't always come with the resonator delete pipes. It depends on the engine and the market. My (European) 325i has the N53 direct petrol injection engine, and the resonator delete is not possible as that section of the exhaust contains an additional emissions sensor and wiring. Still immensely happy with it though!
