Instead of two pipes it uses one seriously thick diameter. It’s the last catalytic converter that merges the two pipes from the engine into one. I don't see any impact on the performance. If you think it will have a negative impact on the flow resistance, be afraid of the catalytic converters within the exhaust system.
I’m no exhaust sound engineer, so I have idea if it will sound that different the one vs two pipe setup.
I guess there is not enough space to route a double pipe between suspension parts and M-differential.
