[Angel And The Wolf]

I've always loved the sound of true duals. I once had the pleasure of driving a true Quad exhaust. I was told that was called a California Quad Exhaust. V8, Two cylinders into one, (four times) four separate pipes straight to the rear. The problem is no exhaust equalization, and less power. I think by cutting the end caps off a regular catalytic converter and replacing them with four smaller caps that each feed one separated quarter of the matrix, I can create four paths that keep the pulses somewhat isolated from the other six. Equalization can be done in the center cavity which the O2 sensor samples, while keeping the majority of the sound in it's proper one of four out pipes.
