C2C overflow question

[riche]

What makes these quite, compared to the overflows like Synergy and others on the market?

Are the manufactured ones just a smaller cleaner looking one of a C2C?

I'm redoing my 180 and since I'have time to plan this out, I am trying to figure out what my best option is.

Either way I have to have it custom made as the Tank already has 2 holes drilled in the back, so Either I make it or have one of the company's make one of there s but with holes custom drilled to fit

Better just have one made with out the holes and drill the holes yourself, in that case you are sure the holes are lined up the way they come together when you when you connect the bulkheads.
