Hello everyone,

I'm looking for options on a good sounding cat-back exhaust for the AWD e90 335i xDrive sedan. I want a 3.5 inch if possible but at the very least 3 inch since stock is 2.5ish. It's very difficult to find anything nice for the AWD and I wanted to see if anyone has had good luck. I have performance turbos and need to have a bigger exhaust and preferably a secondary cat delete.
Any opinions and options would be greatly appreciated.

So far I only see this cobb 3 inch one that sounds quiet:

OP, are you wanting to keep it dual all the way back or go to a single 3-3.5inch pipe?

I'm fine with a single 3 or 3.5 all the way or a dual setup with no secondary cats.
If there is no good cat back for the AWD sedan then I wonder if a secondary cat delete and a nice muffler would sound good. As the car sits now, I have catless DPs, secondary cats, the mid pipe resonator and a modded stock muffler that I welded straight pipes through. The company I bought the upgraded turbos from said my secondary cats are a problem for the turbos so they need to go. My hope was to just get a cat back with no fiddling but I'd chop more of the exhaust apart to get a great sound and keep the turbos healthy.

well. there is no 3 inch or 3.5 inch dual i know of, they are pretty much 2.5, which gives 5 inches total area across all 6 cylinders and is more then enough to support 5-600 HP.

as for sound, i'm a fan of Turner, i have the vrsf 3.5" full race and it's a bit loud and drones quite a bit on the freeway. so i am a bit biased. both options are missing secondary cats. there is also supersprint, but not sure what the piping diameter is, they don't say on their site.

Do you have stock downpipes or catless? I'm worried about drone if I don't buy a full cat back and just buy the supersprint secondary cat delete. I'm leaning more towards turner catback from the youtube video, it sounds amazing.

currently stock downpipes on the VRSF full race.

i'm a fan of the turner titanium exhaust.. although Akropovic also sounds good, but hella pricey. only one selling i've come across stateside is VAC motorsports, and they want 5 grand for it.
