whats a good exhaust for my integra ls b16 swap thats sounds clean and not to loud. and intake?

 

intake I would go with AEM cold air with a dry flow filter since it is easier to clean. I am not sure if they make an AEM V2 for DA's.

Intake manifold there are options like skunk2 and blox but I'd stay stock with the manifold.

Exhaust I don't know.
