Post *340* Opinion on Muffler Delete/ Resonator Delete

How does the 340 sound with either muffler delete or resonator delete? Which one makes it crackle and pop? I just sat in one that had both and i wanted to see how i can achieve just the crackle from downshift. I had a muffler delete on my 335 and it had a bit of drone, i can't imagine how much drone it would have with both on the 340.
thanks for the input

Not a fan of muffler delete on BMW turbo cars ... I recommend you either get downpipes for a more aggressive sound or invest in an exhaust

I know the MPPSK is basically a muffler delete with the valves open and I can't imagine that mid pipe has a resonator so it will probably sound awesome. The only problem is how loud the cold starts would be. I would see if you could incorporate a valved muffler delete so you'll be able to live with it, but post videos if you decide to hack it off I'd love to hear it.

muffler deletes sound good on the turbo engines but the best setup is a downpipe with either stock or upgraded muffler. this will arguably sound better but more importantly retain some backpressure for low-rpm driving

A resonator and muffler delete will have crazy loud pops! Buddy sent a vid and it was crazy. Go for both
