ZZP Mid length header or Hahn shorty header?
 

***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)

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, :lol:

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

that would be the best thing to do if you can afford it

You do not want back pressure... back pressure is bad..

back pressure with our cars = less air movement = less power.

You would just start backing the air up letter less flow through.

you would want the larger DP with the smaller cat back, not the other way around.

If you have a 3" catback.. youll almost need the larger primaries.

Wayy too expensive.

Wow! That's a nice DP, but it's a little too pricey for me. I will wait until I get GM Stage 3, then I will buy a CIA header/DP setup.

Dude, if your gonna break warranty, theres alot more you could do with that money over a stage 3..

There are no decent local tuners and I can't afford to go turbo. I have done my research and Stage 3 is my best option. I'm not going to buy a Stage kit from someone who may or may not know how to tune.

Some dealerships will still honor your warranty if you have GM Stage 3.

Not saying go turbo... im staying in the stage 3 price range...

OTT actually does know how to tune.. every single one of there stage kits has gotten 9 thumbs up... and it produces more power than the stage 3 (unless u are running the race gas mode)..

cost less too :)

Nope. Not every one of their customers was happy with their Stage kit. I was considering their kit, but I was PM'd by a member who had a bad experience with their tune and OTT didn't rectify the problem. GM Stage 3 is still my 1st choice.

Very odd... infact.. i find that HIGHLY unlikely...

You have to realize thats one person, out of many...

The fact that it comes with 60s, and not the 42.5s makes the entire deal...

The next time you want more power, your going to have to get 60s, so thats an extra 200, then your going to have to get a retune anyway, so theres another 200..

You will save ALOT of money.

Also, you going to be okay with no air conditioning?

OTT has helped me with several problems, and im not even a paying customer at the moment.

I can't stand AC! lol. WIndows down and the sunroof open FTW! I might give them a shot. I am going to keep my warranty intact for a while yet.

Good.. im sorry, i dont mean to barage you.. i just wish i knew about it before i did my GM stage kit... i wasted a good 400 dollars now...

yea ac ftl when its like this in florida.. when its 100.. i cant go without it.. lol..

Just showin ya the options!
