Yes, I am still running the Vibrant resonators. "Do they help?" - It's a fair question. Looking back, I wish I added the resonators just by themselves and then took sound measurements just to have the data points. Honestly, I don't think they do much of anything in terms of volume. When the suitcase went back on, that was dramatic.

Aside from this, I have read reports of droning when people remove primary and secondary cats. I think the resonators definitely help with drone. I don't have any drone that I can detect. I think this is the value-add for the resonators. If I had a do over, I think I would have bought the longer resonators which might have had more impact on volume (but this is just a guess). The sound is great but, depending on the track it may still exceed noise limits. My conclusion is that this current setup seems to be about 5 dB louder than full factory stock.
