Why did they had the secondary muffler as my thoughts it would hurt the sound?

I have the original version without the secondary muffler... Still too quiet for me. Getting my downpipe installed while im on vacation. hopefully that wakes it up.

I'm really glad to hear it's quiet. Was concerned it would be loud and annoying. . I want total silence. A sleeper

for total silence, factory would be best.

I want the reduced backpressure for improved performance and economy. I know it will have more noise.
