so with yall's help, ive decided to go with fast intentions hfc, but when about to place my order, it asks if i want one or 2 bungs on each or either side. my question is, what are the pros and cons of having 2 bungs over 1 or 1 bung over 2? what i want is maximum flow and power. thanks in advance, again.

 

I am unfamiliar w/ that term bung. I have the F.I. HFC and i love these HFC. the power gain on this is 16HP to the wheels. I did a before and after dyno on these

 

So was I, but that's the term they used on their website. I'm assuming it the chamber with the cat in it.
