Center X pipe - ECS Tuning vs. 034 Motorsport

[jungy4]

I am looking to get more volume out of the stock exhaust. I see 2 bolt up X-Pipe options that will replace the center resonator.
The one from 034 is more expensive. Does anyone know the difference between these two?

I think they are basically the same.
034 is polished, ECS is not.
Seems that's the only difference, other than price.

The added brace on either end of the 034 unit.

That is a good point. Thanks.

I also think the ECS one is more of an X pipe. If you look at the 034 one you can see that one of the 2 pipes is still straight where the 2 pipes intersect. Maybe this could cause the difference in the exhaust flow.

When I was reading that long X pipe thread, straight piping the center resonator was not recommended. Maybe I am overthinking but just wanted to share my thoughts.
