I need some opinions on what I should do with my exhaust. I was thinking about going with the shoshop y-pipe with highflow cat(stainless), to 2 1/4 all the way back (stainless), running no pre-cats or resonator. In then a set of really nice mufflers. Sound type, I want something that isn't ricey but more tough like sounding. Please let me know if you have any ideas of what sounds good.
Thanks :

you should get 2.5 inch pipe that split to 2.25 at the rear. flowmaters would probally make a nice deep sound but probally not the look you are after.

Ditto. I doubt you'll be able to get a SHOshop Y anyways.

Where could one get his hands on a true dual exhaust??
I been putting a lot of thought in to this as well and I have pretty much decided to go with true duals... any idea how much they are also? thanks for any help

I'm running 2.5" pipe off factory manifolds, precats,and y-pipe. Cherry Bomb for a resonator and a Hooker Aerochamber muffler. It flows like crazy and isn't super loud. It almost sounds like a V8  .
If less is more, think how much more, more is...

Except...
1. 2.5" downpipes (Y-pipe off the manifolds) is KILLING velocity as it is serious overkill.  Major power losses there.
2. Cherry bombs have louvered cores
3. Aerochamber mufflers sacrifice performance and velocity for sound quality by splitting the airflow and then re-merging it
That's the proverbial 3 deadly strikes in exhaust inefficiency. 
Definitely NOT flowing like crazy!
PLEASE do not pretend the Duratec sounds anything like a V8. It is "physically" impossible and I love the way the Duratec sounds.

tRu Bendz wit hthe magnaflow muffler sounds great..it is a little quiet though. That's if you don't want to or can't find someone to make you true duals.

Couldn't have said it better myself.
Best flowing SVT exhaust, while keeping the exhaust velocity up is to retain the stock piping. It's all mandrel bent and actually well designed. A BAT or SHO Shop Y-pipe or simply swapping out the y-collector and cat for a dual inlet single outlet cat is the way to go. Then swap the stock resonator for a Magnaflow res and then replace the two aft mufflers for Magnaflow Mirror Finish Race mufflers (my opreference for looks and sound) or plain Magnaflow straight-throughs.
Stay away from Dynomax Turbo and Magnaflow XL's (also "turbo" style) as they have an internal "S" shaped diverters which really hurt flow and in any case are no different to the stock resonator and mufflers which share the same design. 
For seriously modded 2.5's or 3.0's the only change would be to swap out the center 2.25" section for a 2.5" pipe and leave the aft section alone...

I may not have explained properly I dunno... Stock mans, pre-cats, and y-pipe. Then 2.5 pipe to the Cherry Bomb (perforated not louvered I.D. is only 2") and so on back to the muffler. The Aerochamber muffler looks like a funnel inside, so in theory should increase velocity.(unlike magnaflo which splits exhaust gas up) To cap it off I have a dual outlet glass pack tip to help out with some back pressure, but I think it ran better without it. I will admit fuel economy took a bit of a dive... but hey its only fuel. As for sound, I believe I said "it almost sounds like a V8", you're entitled to like what you like. I'm not pretending anything. Do Your Homework. I work in the automobile industry so I get to do my homework on this stuff everyday at my job... Not to mention with input from ASE certified techs and a couple of techs who race. (one Pro-street and one Super gas) 
If less is more, think how much more, more is...
