Lil bit confused
I am not 100% sure on the difference between EAS and ACM. I believe EAS does the same mod that my exhaust has. Essentially, the exhaust has four baffled pipes that run across the muffler cans, crossover, and exit out the opposite side. This exhaust has two of the four baffled pipes replaced with straight pipe for more volume. Some of the mods also bypass the resonance chamber which increases volume and drone - this one does not.
