***EDIT: BOTH OF THESE ARE NOW FOR SALE!*** ZZP mid length **SOLD** $325 shipped OBO for the Hahn Shorty ($525+shipping new). Both headers were used for less than 6 months before the owners traded their SS/SC's in. The Hahn Shorty is stainless. It was painted by the previous owner to make it "pretty" for selling it. lol. ***I WILL ONLY ACCEPT PAYMENT BY PAYPAL***. PM me if you have any questions.

I have purchased 2 used headers from members on our local club site. I am going to keep one and re-sell the other. I am currently running the stock header and DP with a Hahn 3" catback. I plan on getting GM Stage 3 in the near future, so for the header experts out there, which should I keep and why? Thanks. ***EDIT: BOTH OF THESE ARE NOW FOR SALE!

Header #1: ZZP Mid length header/DP
-1.5" primaries
-ceramic coated header
-2.5" stainless DP
-extra 02 bung for wideband (plug included)


Header #2: Hahn shorty
-stainless 1-5/8" primaries
-bolts up to stock size DP

 

Well.. personally i like the hahn shorty header better..

but the mid length will gain you more through out the entire rpm range..

the shorty header, more up top.

 

Wow that shorty header from hahn is sexy. Ide say the midlegth though for gains.

 

yes yes.

 

Thanks. I am a little concerned about the ZZP flex pipe breaking. They have a warning on their website that says if you don't use solid engine and trans mounts, the flex may break and it won't be covered by warranty.

 

i never had a problem with my flex pipe even before i had my mount but they did changed how they put the flex pipe on do you know how old the one you have is

 

The holes on the flange of the ZZP header that mount to the block are WAY bigger than the ones on the Hahn header. How much will that effect performance?

It was made in July or August I believe.

 

The openings in the mounting flange. This is the Hahn. I don't have pics of the ZZP, but they are bigger.

 

that is for a 2.2 or a 2.4 go with the zzp

 

They could be opened up a bit with a die grinder and some patience I guess.

Hahn only makes one header for the Cobalts. It was on an SS/SC before. It says on the Hahn site that it was designed EXCLUSIVELY for the 2.0 LSJ.

 

^^ tey are both for a 2.2 or 2.4...lol The LSJ ZZP has 1.75" primaries. I would go with ZZP cause it clears up your downpipe bottleneck as well

 

Well.. hahns primaries are bigger than zzps (the tubes itself)...

Why dont you try them out first?... then decide..

ZZP ... only because id like mid length

 

i just look at hahns website it is made for the ss/sc but the holes just look to small

 

The previous owner painted it to make it pretty for selling it! lol

Which one would be louder in the cabin?

 

y dont you try them both

 

Because I don't want to do that much work or pay someone to install them twice! lol

 

ive had my ZZP now on my car for about a year and I have no problems with it and i love it

 

i would go with the zzp then
mid length>shorty

 

I'm leaning towards the mid length. I like that it moves the cat under the car. Can I bolt the header and DP together before installing it, or will it be too difficult?

 

i cant remember i know that i didnt

 

Thats a fairly random reason to like it,

1.5s are a tad small for a stage 3 LSJ I think

 

i would go for the midlength, just cuz if you get the shorty, the stock dp will still be a bit of a bottlenecj in the exhaust system, whereas everything will be nicely opened up by the midlength combo and you will gain more power throughout the entire rpm range

 

Do you think the 1.5" primaries and 2.5" DP would help with low end torque since I have a 3" catback? Would the extra back pressure provided over 1.75" primaries and 3" DP be beneficial for my setup?

I just thought it would make the whistling sound that people talk about with standard ZZP DP's less audible. lol
Maybe I will just sell them BOTH and get a ZZP mid length with 1.75" primaries and 3"DP.

 

i think you should sell both and buy the zzp mid length with 1.75 primaries and a 3in. downpipe

 

You read my mind! lol
