Keeping stock DP but going stage 2+ (HPFP, BM3 tune)

Hi everyone.

I have the HPFP installed and BM3 (currently flashed to Stage 1), car is otherwise stock outside of xHP trans tune.

I was planning on going with a catted DP but after trying a two, I just don't like the fuel smell and raspy sound. The OEM DP sounds the best for me and mitigates smell the most.

Can I reliably run the BM3 Stage 2+ tune WITH the OEM DP? I understand I wouldn't maximize the power of this tune, but surely it will be miles better than Stage 1.

Is there any risk of this? Alternatively, has anyone went with a catted DP then installed a downstream 200 CEL cat in the place of the resonator or something to reduce fuel smell?
