So it sounds like the Dinan design is faulty, as you've had 3 mufflers and all made the noise. Hopefully that new spring fixes the rattle and they can make that as a running production change to prevent future issues. Glad to hear that they worked so hard to get the issue fixed.
Also, do you happen to know the inlet size on the Dinan tips? I like how the muffler sounds from the sound clips but really don't like how big the exhaust tips are. I'd like to see if I can use one of the AliExpress-sourced tip options with the Dinan muffler. The recently released ValveTronic might be an option as well. As much as I like the Remus and Akra parts, there is no way I can justify the price (like nearly 10% of what I paid for the car)
