So I went to install the rest of my exhaust today, the Hahn cat-back is already installed. I took off the dp, and I took off the stock header (which is a pain in the ass). I go to put the hahn header on and it fits, but the bottom of the header rests on a part of the transmission. The transmission piece goes across to the other side of the tranny. When I tighten the header down, the pressure from the header pushing down on that bar causes the transmission to leak on the right side where that bar goes across. So I take the header off and I compare the openings with the stock header, the stock header has bigger openings. I'm either thinking this is very poor design, or hahn sent me the wrong header? I need some answers.




Size Comparison (look at the holes on the new header (left) compared to stock (right)

 

wtf. they look smaller. or is that just me. i would expect a much better design from hahn than this. this is just to hard to believe

 

wtf???

 

Thats not the tranny, thats the water pump. The water pump is the box on the right that that tube comes out of. It runs off the Timing Chain.

 

Hahn is getting their header back.

 

so whats up with this header? wrong on?

 

i guess they were more worried bout making a gt35r cobalt than getting there header right

 

hahn makes the most beautiful exhaust i have seen and to see this header is just, WOW. i dont belive it. but if you ever go exhaust, dont hesitate with the 3" hahn

 

vibrant ftw

 

you could just dent that pipe for the coolant, but i can't belive they would sell a part that does that. aways seems like they have such good stuff.

 

nah thats ok lol. I'll send this back and buy a gmpp header but keep the hahn dp and cat-back

 

they r as good as it gets what they sell..eveyone makes mistakes so no problems there



hmmmm not to sure about that,,,gm header is not special....stock is as good..my stock outlet was like 1.8inch and vibrant was 2.5 .... stock is way to small or gm anyhow

why now just wait for hahn to make u a new one

 

I could do that, but we'll see.

 

gmpp header = ****

 

if you bought a shitty burger from mcdonalds... would you want to sit and wait for them to make you another shitty burger? or go across the street and get you some real food for the same price?

 

i cant believe that.

 

X2..why ..that would be a waste of a sick DP/E ..... do it right the 1st time ... cost more doing it 2 times

 

qft...

Would render the rest of your system useless....

 

the header they sent me has smaller primaires then the stock header though. Why should I take the chance of them sending me something else when it will probably be the same size primaries as the one they sent me, and it doesn;t even have a 3" exit, it's only 2.5" that isn't a true 3" header.

 

post number 15 ftw

 

dude go with the pacesetters header with armor coat..i've been running that i love it ..fit great too

 

if you guys are suggesting other headers, send me some links so I can check them out. For example, vibrant or pacesetter.

 

if they send u a new one will it be 3'' exit and bigger primaires ?

vibrant header is mid lenght header and its 2.5" u wanna go 3'' only

i thing ZZP has what i need

 

it just really pisses me off that I pay 1600 dollars for a full exhaust system from a company that is very reputable, and this **** happens. Nothin ever goes easy for me when it comes to cars. And to top it off, they sent me the ******* downpipe, with only two bolts, when I need 3 bolts to connect it to the header. So I had to take a trip to home depot to get one more bolt.
