Hi, I was wondering if anyone had any ideas or recommendations on what the best exhaust set up be to pair with catless downpipe? I have a 2011 335i XDrive with a catless downpipe. I am not looking to purchase a full exhaust but to modify the stock one from the cats back. So far I was looking into possibly muffler delete? or replacing muffler with Vibrant resonators. Was also thinking of swapping secondary cats with Vibrant resonators as another option. I'm really just looking for a deeper sound from the exhaust. What do you guys think would be the most bang for your buck option?

Thanks,
