simple question about straights

[lambo101]

sometimes when i hear a person say they have a "dual exhaust" they have "dual exhaust tips". anyways, i was wondering how much more power and better sound can a 3.4 gain from running straights, rather than dual tips coming from a single muffler? of course this means 2 cats and 2 mufflers as well(dual cat-back exhaust if you will). just wondering if it's worth it.

its will probably sound better and i say this because of a dual 3.8 i have heard in person but as for worth it for power...not really

well, the reason i ask is because, although i didn't think that the immediate power gain that a straights exhaust would have over a dual tip would be that much greater, i do plan on putting a twin turbo in my car. i was wondering if having one turbo on each pipe would result in less backpressure, thus creating more power. so i guess my real question is, is it worth having a TT with a straights exhaust rather than a TT with a "dual tip" exhaust?
