thousands of people have done the entire exhaust. header, high flo cat and then the cat back. dual exhaust is just for looks. if you want performance go with a single muffler system.

But i guess my question is how do i go about that without setting off a code, i mean theres 3 sensors.....A single exhaust you say, why is that? I was thinkin one single muffler with two outlets for the dual look.

if its done right it wont throw a code. have a local exhaust shop install it for you
most people do dual exhaust they use 2 mufflers like shown here
a dual exhaust adds weight that you dont need. the weight of the extra piping and muffler.

....what 99red said. Also, it is gonna be quite a bit louder with a dual set up. I had the rk dual quad tip set up, and while I liked the novelty of the sound at first, it wore off after long drives and long periods of ringing in my ears (seriously). Go with a header, high flow cat, custom cat back exhaust, and a nice muffler. You'll probably like the sound of that. You can also think of adding a resonator between the cat and the muffler for more sound reduction.
Oh, and since I eliminated the duals, my car feels more torquey. (if thats a word.)
...don't hate!.. respect people that have talent, even if it is in something you don't like or understand.
I have the magnaflow dual catback and the sound is a bit too loud inside the car... it's unbearable when I'm driving below 2500 RPM.

Kyle - I have a 2.4 (1999 Z24) and it's just from the cat back (original cat). Besides a short ram air intake, I have no other engine mods. It sounds nice at higher RPMs, but below 2500 it turns into a horrible low droning noise that makes my subwoofer sound like a pussy.
