E53 4.4i exhaust question

[zu11y]

Hey guys, I need some help with my exhaust system, since I am from the UK we use different words for exhaust parts so please bare with me, I had my back boxes (the two rear boxes that are part of the exhaust tips) removed.

I am very pleased with the volume of the exhaust, but im not to keen on the tone, don't get me wrong it sounds good, but I want that popping and crackle sound.

how would I go about achieving this, I was thinking of removing the centre silencer, and going with the straight pipes, but I am worried it may be too loud as it would be a straight through system from cat back.

any help is greatly appreciated.
