Does anyone have experience with what N54 catted Downpipes work with our z4 E89 sdrive35i? Situation arose where my cat on bank 1 failed and needs replaced. They are expensive so if I’m going to replace I might as well go aftermarket.
From what I found on the internet, Etek makes a Downpipe specifically for e89 but they are expensive.

I’m wondering if VRSF 3" Stainless Steel Catted Downpipes fit since they are half the cost.

Honestly I tried searching the bimmer forum but it kept pulling up all the models and I’m wondering for E89 specifically. So your help here is appreciated!!
