So is the zzp midlength header just a pacesetter with a different collector, is it stainless steel, and what is the outlet size on that header? What would be another reasonibly priced midlength header/downpipe combo? I will be ordering something here in a couple weeks and I am just looking for some more information. I have been searching but I haven't really found what I am looking for.

 

with the 1 3/4" primaries is a 3" collector, i just ordered it should come in tues ill let you know how it goes.

 

Yeah let me know and if you would could you snap a couple of pictures for me. Is that header stainless steel

 

no but you can get it ceramic coated or high temp paint, the d/p also has the option of stainless and w/ or w/o a cat... i can def take some pics and prob a few sound clips as well for you.

 

I think I will get ceramic coating with the stainless non catted downpipe. Does anyone know what kinda numbers I should see from this combo.

 

it really depends on what you have done on a stock cobalt expect 10-15 whp and on a modded up to 25 whp.. i should be getting mine shortlty waiting for the delivery truck to get back so i can go pick it up ill get some pics and it should be going on tom with the help of my buddy dave

here you go...
header- 1 3/4" primaries to a 3" collector

DP- 3" with highflow cat, 2.5" exit

inside of collector

header flange

collector welds

 

Looks good I will be ordering mine either this week or next week. Let me know how it feels when you get it on the car.

 

i got the same thing being installed tomorrow moringin cant wait on my b-day too

 

these pics are all mine. including the first one

zzp header:


zzp downpipe:


installed:

 

so how do u like it? i know ill find out tomorrow but what should i expect?

by the way like the first one lol

 

Does it bolt to the head without modifying the nuts that hold it on.

 

actually the top nut on the passenger side needed to be dgrinded down a bit.

i like it, but i wish i had gone catless

 

i just installed mine last night, worked real damn good
until i lew off the nuts that hold on the downpipe.
i guess meth and a 2.6 will do that.
my advice grab some grade 8 bolts to attach the header to the downpipe, you can thank me later....

 

shaunmcdee did you have to modify any of the nuts that hold it to the head.

 

i forgot to say... that happened to me too. i just used some loctite

 

They come with a new gasket right and I see you guys go the painted how is it holding up. I think I might just get the ceramic coating but I wouldn't mind saving $120

 

the paint burns off in a couple of hours ..

no. but you dont need a new gasket. i got one $14 @ chevy

 

If you put in the comment line that you want the 2 flange bolts replaced with grade 8, we can do that for no charge. You have to ask in the order though, it can't be in a separate email.

 

my car been at the shop since 9 am to get it installed and i called at 12 and they saud that they havent got to it yet...andi was told i am first on list cause i scheduled an appt. and it s almost 3:30 ...????

 

Redline 24 - i didnt have to modify any of the bolts, everything bolted up nicely. There was a few tricky ones though.

Chevysalesman614 - no man, i literally broke the bolts, heres a pic or 2

pic of bolt that stretched and blew off


and pic of seperated downpipe and header after bolts broke.


Zooomer - I love the header and all, but no offense buddy, for the price we pay, we shouldnt have to ask for stronger bolts, i think they should come standard. Saves alot of headaches for everyone.

All in all, even with the broken bolts, and a slight leak i cant pin point (only happened after the blow off bolts) The header was by far one of the better purchases ive done. And i kcik myself for not ordering sooner.

 

zzp header? does dat come with the exhaust manifold gasket..mine didnt for apparent reason the shop called me and now they have to order one is that expensive???

 

Does the GMPP Performance Exhaust have a cat in it, or if i go catless on the ZZP DP will I have no cat at all on my entire exhaust? I've been looking into ordering the header and dp combo as well, I wanted to make sure that everything hooks up together right and I don't end up without a cat when the cops pull me over... sigh it happens at least once every two weeks for me. Bastards stop me for no reason just to check my license and ask me what mods I have done to the car >.<

 

im not talking bad about anyone. so don't take it as such.

thats looks damn near identical to the pacesetter.

 

same thing happened to me... was testing it out on I-87 and i hear a ping so im like **** thats not good. then i start to hear an exhaust leak and me and my friend just look at each other. then few mins later i hear a second ping and the exhaust get insanely loud so we pull off and see the d/p just hanging. got a new gasket and some stronger bolts and its good to go now

not really... pace setter looks alot different in many aspects

 

I like the zzp one because it has a 3 inch collector. Area47 what size is the collector on the pacesetter.
