E92 335I exhuast system help

Hi guys

Can anyone who has done any exhaust work remember if our systems are

Downpipes with cats --> Secondary Cats ---> central muffler---> rear Muffler ?

I've been thinking of looking to get some straight through pipe from second cats onwards but couldn't find any information regarding any drones or if the coupe has central muffler, some says only the saloon version has it and while looking at realoem i've found that my car has central muffler??

I have aftermarket muffler which sounds great from outside but i cant tell any difference from stock when i'm inside the car..only slightly deeper roar.
