Divorced Downpipe VS. 1 piece elbow-downpipe
 

can somebody help me out, I'm about to buy a downpipe for my 7m-gte but i'm not sure witch one to get, i heard that the divorced downpipe is better...what I want to know is HOW MUCH BETTER is it? is it worth $100 extra compared to the 1-piece elbow downpipe? what about HP difference?

here is where I'm planning to buy it http://www.bicperformance.com/products.htm

thank you

My opinion
 

This is just pruely is my opinion and only that I think it's better to not to go with a divorce down pipe becuase if you ever have to replace it or have trouble with it with an elbow you can at least replace the pipe or elbow I don't see any advantages as far as flow......just my unprofessional opinion
