335i muffler on single outlet f30

Hi,



I don't know witch forum would be right for my question, so I just put It here..



I'm thinking of buying a used oem 335i muffler to put on my car. I have a single outlet non-m sport exhaust.



I know there will be some mods to make it fit, but my consern is how would the 335i exhasut line up with the existing bumper "cutout". Well it obvious that I need to make one more "cutout" but will the existing one line up with the outlet? Or do I need to buy a 335i rear bumper?



Thanks.
