Aftermarket muffler

I currently have a 2011 323i and was looking to put a muffler on it for sound. Anyone have any suggestions?

Magnaflow muffler. Stainless steel, and a deep tone without being obnoxiously loud.

I would recommend the Borla - slightly less Boomy compared to the mangnaflow.

Do 3" in/out for the best results.

I've been leaning toward a magnaflow but I'll check the borla out! Would it be a good idea to remove the secondary cats as well or would that be too loud?

I have a Borla exhaust with hanger arms already bent and welded up for factory mount locations. I even have a custom bracket made for the rubber isolator that mounts to the stock exhaust. The exhaust is painted black so it's not shiny. The previous owner had installed it and I recently upgraded to a BMW PE. Located in 35824.

Ideally I've been looking for a blacked out exhaust, I feel it accents my car very well with my setup.

I recommend a AA Gen2 axel back. It has a small muffler and a drone chamber. I have it, and I powder coated the tips Black for a stealthy look. Came out great!
