anyone have these?
how loud would these be with a straight pipe true dual.
here's the description for it!!
Using advanced gas dynamics and sophisticated noise cancellation acoustics, Moroso engineers have developed the spiral flow racing muffler. Specially engineered spiral baffles divide the exhaust flow into two separate paths, significantly reducing noise levels with minimal backpressure. It has a round tube case with a centered inlet and outlet, and features an all-steel construction for durability.

I really don't think they were anticipating a rotary breathing through the muffler when they wrote it.
However, I run a 3" exhaust all the way back with no cat and an HKS Hyper. All things considered, I happen to like it!
HEY, WHAT'D YOU SAY???
