iirc the reason is because the right side is a straight pipe with no resonator

Quote:

Right muffler has less sound dampening material than the other. Exhaust air flows more freely to that one, hence it gets dirty faster than the other.

I believe a true dual-exhaust would require 2 separate cats / headers. Each exhausts need to connect up to the cat without splitting off at the Y.

^ I'm aware that only the left is a muffler, but the right is just a can. I'm wondering if there are any benefit performance wise besides more noise?
