Catalytic converter question

[ZV Cobra]

I had to put my stock mid pipe on to pass emissions and want to put my offroad back on with 2 smaller cats. My question is regarding sound. I found two converters from magnaflow but dont know which will alter the sound the least.

1)

2)

I am assuming the second one just wanted to check before I bought them. Thanks

second one.

I need to replace a set on my car, going with the second style as well.
