I thought downpipes were only for Turbo cars? Will this fit my non turbo 2.2?

Cobalt & Ion ---> ZZ Performance

 

yes sir. direct fit replacement.

 

downpipe = catalytic convertor pipe

 

Gotcha, so heres my second question... lets say I got that ZZP downpipe - would it bolt up to the rest of my stock exhaust? like wouldnt the flange sizes be different etc?
Also, if I went catless, is there any harm in that? Codes? Car running rough? Fail emissions?

 

If you go catless, you will fail emissions if they use an 02 sensor. You may get a cel, but that can be tuned out. I would personally get a high flow catted downpipe on a 2.2, catless is gonna sound raspy.

 

Well they offer a MagnaFlow cat pre-welded into the downpipe for an extra $50... should I just go that route?

 

That'd probably be your best bet. A bit more refined sound, and you should be able to pass inspection, and you won't get a cel.

 

Awesome, thanks for the help man. Now i'm trying to figure out what route I want to go for an exhaust.

 

the flange to the catback should bolt up. the flange to the manifold might not depending on what you get. before i purchased i would double check to make sure the downpipe you get has the compatible 3 point flange and not a 2 bolt flange and double check to make sure its long enough to fit for the stock manifold and its not designed for a midlength header or anything like that.

 

^^truth there. didnt think of that

 

So I should probably just contact ZZP... ha

 

yes. and what i said was under the assumption that you still are using the stock manifold

 

Which I am

 

ya then contact ZZP and see if it is compatible with a stock manifold

 

Awesome, is there a rep on here for them? or no

Edit - nevermind, i found the rep and messaged him

 

Update:

Got my ZZP Downpipe today, 2.5" piping, Magnaflow Cat, bolt up flanges... ZZP FTW! I'm going to order my Tsudo exhaust in the next few weeks and then ill get it all installed and post up some more pics/videos.
