True dual piping vs. single pipe dual tip.

True dual piping vs. single pipe dual tip.
Ok, I've tried searching but didn't yield very concrete results, a lot of opinions and theories..
I would like to know if there is any sort of real dyno record as to whether a true dual really is much better than a bigger diameter stock single pipe configuration? I can see the true dual being more beneficial, but with all the weight in the extra piping it makes me wonder.. also the whole thing with N/A vehicles needing back pressure to retain scavenging needs is sorta beyond me as i'm coming from a turbo vehicle...
I guess my question is whats really the difference between a true dual 2.5inch piping vs. a single 3inch piping with a dual tip muffler...
I was trying to come up with a custom exhaust layout.
Thanks

I do like the idea of that x-pipe being there.. lots of ppl seem to like the x-pipe deal.
What really is the difference in sound? it seemed like most of the single pipe exhausts i've heard on youtube seem to retain that VQ motor growl or "pur" better than the duals.. i could be wrong..
what do you mean the extra cutouts?

well, if you do a straight through single setup, there'll be a lot more drone and possible rasp. most systems sound great from the outside, but you'll be inside dealing w/the extra "noise." if you plan on doing a single pipe to a larger muffler w/2 tips similar to the OEM or Nismo setups, then it should sound fine but you'll have more weight and less flow than a straight through single. also if you plan on any type of single pipe then make sure you get or make an HR-style y-pipe.

yea, i managed to "find" myself an HR y-pipe from an 08 350Z so thats covered.. I was thinking about keeping the exhaust OEM style with the dual tip muffler instead of a single straight through.. Not a big fan of loud exhausts and want to keep it as quiet as possible but with just a slight increase in the exhaust note... was thinking about doing resonated test pipes as well, since we dont have much of an emissions law in the county i live in, in TX.. plus, i'm a state inspector so i can do it myself.. lol.
So yea, I was thinking resonated test pipes, to a flowmaster muffler in OEM exhaust configuration. i think it'll definitely be enough to free up some flow there while saving a bit of weight..

Good info for those who dont know Mark. How have you and the family doing? I miss getting car envy everytime you drove by my house. lol btw its Phil, i changed my screen name on here
I had the coupe mid and hr y pipe (I have a sedan), it was nice and not to loud and a little bit more power. Now i have the stillen TD exhaust and it is amazing. It is a noticeable difference and its a little bit louder under normal driving conditions and has a nice deeper VQ sound. Now if you floor it it can and will get loud (interior noise is not loud) while maintianing the VQ sound. I wont go back to a single after having a TD exhaust.
