I found a cheap front pipe but don't know if it's off of a 328i or 328iX.

They look identical but one is 18307633124 and the other is 18307633123.

I have the n26 and would use this to replace the second cat. Then possibly the resonator with the supersprint centre pipe.

Any one know if they're interchangeable?

Just following up on this…there is a more expensive option to go with supersprint 983832 and couple that with 987813. Though this starts to get pricey.

what is a "front pipe" can you be more specific? If you are referring to an engine part then yes, they probably are interchangeable since x is just xdrive designation ...

The "Front Pipe" is just exhaust piping between the resonator and the muffler. Seems like it should be called the back pipe but whatevs…

The geometry has to be different, it would likely connect up but I think it would not sit flush to the car. XDrive is quite a bit higher up front. You could probably make it work by bending the hell out of it.

Instead I wound up spending far too much money on a pipe from supersprint https://www.supersprint.com/ww-en/bm...on-4x4.aspx#!/
