i have port noise from a 4 inch pipe port i made... i went to calculator and figured out that if i get my port up to 6 inches i should be fine and there wont be any more noise. But i was wondering can i leave my 4 inch port and and instead just add another 2 inch port or will that still have noise?

 
4" port + 2"port does not= 6"port.

how big is your box?
Its 5.54 cu ft after displacement. i figured it needs to be a total of 20inches of port if i use another 4 inch port. but if i add a 6 inch instead it only needs to be about 10 inches
