I'm looking at the Bomiz 304 Valved Axleback just so I have an option to make it quieter. OP does your Bomiz system have vacuum or electronic valves?

They are electronic valves and I really enjoy being able to quiet it down. Even when I had the full catless system the noise difference was insane. I could very comfortably drive the car at midnight through neighborhood areas without attracting attention. I will say though, I don't know if this has changed, but my Bomiz system took 6 months to come and was 3 months late, so just throwing it out there.
