Dual or Single exhaust? 350z HR

Sorry, I know this is too random and it's a matter of preference. Just wanted to know yall's opinions, performance and looks wise!

I'm thinking about getting this ISR GT. I have a full OEM exhaust system, and I'm not changing anything other than this specific part.

Thanks!
