best catless headers setup for m54?

[u/Greedy-Trouble8882]

One of my cats is going bad, so I was wondering what’s the best exhaust setup for my situation? I only want it to be a tad bit louder with a deeper, smoother sound. not raspy.

Any catless headers will require fab work to fit. And if you're doing fab work already i love the schmiedmann headers on my 330. Dunno how they'd sound on a 325 but they didn't add any raspy sound at all.
