last minute ??'s before ordering zzp exhaust
I'm getting the mid length header and downpipe combo. But I don't know what I should do as far as all the options go. Link:
http://www.zzperformance.com/cobalt_...=545&catid=155
Model: is it worth the extra $20 to get the 1 3/4 inch?
Option 1: I'm going to do the Magnaflow cat for the extra $50, but will my stock o2 sensor plug right in?
Option 3: I am going to get some custom built cat-back exhaust later on down the road. So I don't want any of the weld options. So to bolt up to the stock cat-back I have now, I'll have to get the 2.5" exit, right? But should I go for the full 2.5", or get the 3" with the 2.5" exit?
Thanks guys! I just don't want to accidently order the wrong thing and then be pissed off about it.

2no it wont plug right in, you need to splice the wires and make them like 3 inches longer.

I highly doubt there will be a differnce for the extra 20$ for the paint, ceramic is the way to go. yes your 02 will plug in, And as for the exhaust it depends on how much power you plan on making down the road and how loud you want it to be, but yea the 2.5" exit will bolt up to a 2.5" catback.

the larger primaries are totally worth it
*side note, my high flow cat is clogged already(1,200-1,500 miles).. If your car is tuned a little rich, i sugesst you go cat-less

So where do I have to get an extender (I'm a chick so ***** jokes don't apply here, lol)
And ok, so how is the sound difference with 2.5 vs 3"? I'd guess the 3" would have a bit deeper tone...
But wouldn't cat-less throw CELs and make problems for my warranty? I'd rather go catless if I could, I believe I am a little on the rich side with the GM Tune...plus no emitions law here in Wyoming

i chose the 2.5 cause until i go turbo, i have no need for a 3" exhaust. 3" would probably be louder, but i dont think the pitch would change.. thats mostly the muffler and the resonators

3" would probably add a little more on top end, but I would guess that it would take away more of the low end power than 2.5" would.
Last question though....is catless gonna make warranty problems and throw CEL's? And what does the o2 plug into if there is no cat?

you only would benefit from a cat-less pipe, if your car has been dyno tuned, and running rich.
see how dirty the muffler tip is? thats unburnt fuel, and carbon deposits from running rich
Now I hope it'll get here before the coming weekend.....

A complete bolt in exhaust solution for your Ecotec. Comes with header and downpipe, and installs in under 2 hours. Allows you to run smaller pulleys safely. Look for gains between 15 and 40 horsepower, depending on your mod level.
This combo is setup to connect to a stock or aftermarket catback. Unlike our shorty header and stainless downpipes, these must remain as a combo and are not compatible separately with the OEM manifold and downpipe.
14 inch average primary length
Near equal length primaries
Available in painted, ceramic coating and stainless
3/8 inch flanges prevent warping and leakage
Header and both downpipe gaskets included
Smaller primaries for maximum power and torque on 2.2 and 2.4 applications
Larger 1.75" primaries maximize supercharged setups
O2 extension included
Ceramic coating on headers holds in heat for improved performance. 1.5" headers should be selected with 2.5" downpipe, 1 3/4" headers can be selected with either 3" or 2.5" downpipe sections. 3" downpipe with bolt in 3" exit should only be selected with our 3" catback system. For custom exhaust systems please select a weld in option for the downpipe exit. 2.5" bolt in option bolts to all stock or aftermarket 2.5" catback systems.
*No cat option is for off-road use only and requires PCM programming for removing the rear O2
