[MMN]

Hey guys, is there any specifically sized aftermarket dp that is better than others. Seeing a lot of 3", 2.75" and 4" types. Which works better for an N54.

Being an N54, you will need 2 DPs. I believe theres not much difference from a 2.5" - 3".
You wont be able to fit anything bigger than a 3" thou, due to space.
Just make sure that theres a tapper somewhere along the pipes, as our exhaust system from the midpipe is a 2.5".

These bigger down pipes youre hearing about will more than likey be for the N55s.
