So I want to upgrade my exhaust on my 2017 330i but AWE only sells a singled sided dual exhaust for the 330i. Does anyone know if the AWE 340i exhaust will work on a 330i? Has anyone done this or have experience with this? I very much want the aesthetic of a split dual exhaust rather than singled sided. Thanks in advance

The axle back section will fit your 330i but you'll need the 340i lower bumper insert (if you have the M-Sport bumper). Otherwise, you'll have to cut the bumper. You'll probably need an adapter for the exhaust pipe size difference, as the 330i is 75mm and stock 340i is 80mm.

The midpipe is completely different. AWE used to sell the 330/430i midpipe separately, but they no longer do that. You might be able to get AWE to mix and match for you, but hard saying. They do sell a quad tip kit for the 330i, but that requires cutting or an aftermarket lower bumper insert.

Thanks a lot for the info! Appreciate it.
