I dont know much about this stuff. Whats the difference between the catback and turbo back? Which one would you guys recommend? Which one has better sound and performance?
Zzp catback or zzp turbo back?

So i should probably go with the catback then right? Im not wanting to get the trifecta tune yet

That is my understanding. Lots of posts about this in the Trifecta FB page and his WOT web site.

If you get the turbo-back you most likely will need a tune because it deletes the first catalytic converter, which will throw a CEL. And if you left the car with bad O2 readings it could create all sorts of problems with your air and fuel system. I'm not 100% sure on this stuff but it's what I've heard.
Go with the catback, it doesn't do anything for performance but it sounds very nice. I used to have one.

So far we're mostly correct.
There are 4 parts to the sonics exhaust, which is about the same general setup as all cars.
Starting from the replaceable parts of the exhaust near the engine to the tailpipe we have the following
-Downpipe (header for the 1.8)
-Midpipe/flexpipe
-2nd cat
-Cat-back
Cat-back= replacing the back ~1/2 of the exhaust. This would be the piping and muffler/resonator. ZZP also offers an option for their cat-back that replaces the 2nd catalytic converter with a "test pipe" (straight pipe) for better flow.
Turbo-back= replacing the entire exhaust starting at the turbo discharge and going all the way to the tailpipe. It will provide the most turbine noise (only audible at low rpm and stepping into the throttle) and also the most power.
It does not require a tune to run, however since you're replacing the 1st catalytic converter it will eventually throw a "catalyst efficiency" CEL, typically about 200 mi the 1st time and every 60-140mi afterwards. With Trifecta you can disable that monitor so the code never pops up, but it won't affect actual operation. Or if you have an Ultraguage, Scanguage, or Torque app you can just clear the codes when it pops up.
Here's a link to some Dyno results that MPFab posted up using his "Anaconda" 3" DP/midpipe combo and the Anaconda + custom 3". The results will be somewhat similar to what you'd get with the ZZP turbo back kit or just catback kit Link: http://www.sonicownersforum.com/forum/morgan-performance-fabrication/9919-mpfab-dyno-graphs.html . I'd also highly recommend looking into MPFabs "anaconda" DP/midpie vs ZZP's DP+ midpipe, it's made to insanely high standards and is a little better flowing (not that the ZZP is poorly made).

Awesome thanks for all the help and advice! Is mpfabs wedsite down? Because i cant get it to pull up at all

You can run the turboback without a tune but it will require the "J"fitting from Vibrant to fool the second oxygen sensor(essentially your O2 is angled differently so the computer thinks its reading clean air) I and other members have run it this way with no issues

As I now have Black Turbo's old DP & MP with a J fitting, I can confirm this works.

And with my new one I am running the same with no issues.

I think i might just go with a catback for now and mpfabs anaconda

I was running this as well with no CEL when I had the DP installed. No monitors can be "disabled" here in New York. Part of NYS inspection is to check for "monitor readiness".
