I bought a set of stainless ceramic coated DT headers in April. I installed them and I thought everythig was ok. In May I bought the uprev and did the logs so i could get my first map tuned. It turned out It looked looked like I had a leak on the left bank, So I took it back apart figuring I had messed something up when I installed it. Once I had it apart I could see the leaks and it was pretty clear why.

So I called Nick at DT and told him what was going on and he said he wanted to get the header back so they could "fix" it. The problem with this is I live in Florida and its going to take 5 days for it to get to him, then they are going to have to fix it, then its 5 days back and I cant be without my truck for two to three weeks. So we agreed that they would get me a new one but they didnt have anymore so it would be about 5 weeks but he wanted me to call back after 2 weeks and see how things were going. I called again after 2 and a half weeks to check on things and Nick tiold me they were in welding and I should call again in a week and a half. So today I called and he tells me that he was wrong the that the headers being made now are the mild steel not the stainless and he still thinks I should send the one I have to him to have it fixed. I got really pissed because I paid alot for the headers and I just want them not to leak. I cant even get my e-tunes done because of the leak. Another problem is that it sounds like ****.
In his defense its only been 4 weeks so its not like its gone on longer then we agreed but today he didn't even give me a time frame for when I would get them.

I am asking you guys what you think I should do and am I wrong for being upset?

I replaced the the gasket twice with the OEM gasket and the last time I tried the felpro. On the OEM gaskets I made sure the silver side was facing the head. I followed the repair manual. I did tighten the nuts down again after 300 miles or so and both side has some that needed to be snugged up. The flange does not look like its bad. To me it looks like even if they surface the flange it will still leak because the hole itself isn't an oval making it too large. If you look at the rings around each hole you can see on cylander 5 (third hole) the hole is wider then the ring. If you look at the stillens they make ovals like the oem manifold.

I tried moving the manifold all the way down on the studs and I actually got the leak to move to the top of the gasket/header.

maybe this hole thing has just made me crazy and I am completly wrong. I just dont think that after spending 750 bucks you should have to send them back to be "fixed" and not have a truck for 2 weeks have to pay for the shipping again. I looked into having a local shop grind the flang and its going to be about 70 bucks but why pay to have your new header fixed.

Look at how nice these look. I didnt even get ovals I got saturn shaped holes.

see the difference. thanks titanss for finding that post its exactly what i thought.

 

[LoseMyMind]

you got that right. what would you do import.

 

[LoseMyMind]

I want a new one.
Yeah there is alot of room to adjust them once they are on the studs because of the elongated holes.
I don't see how they could fix it without alot of work being done to it.

 

[LoseMyMind]

I am going to call them again.

 

[LoseMyMind]

I got this back from DT today.

""Anthony,
That’s fine. The new header you get WILL NOT be the original OVAL design but a combo round/oval as these headers also fit the Infiniti QX. The port you got does not look the best I will admit. One way we remedy situations like this is that we will TIG the affected portion of the flange which is actually harder than the flange itself. Then clean it up and surface it true""

 

[LoseMyMind]

I guess thats what hes saying. I dont see how the QX makes any difference I thought it had the same exact motor in it. Again hes not saying when he is going to get me my new one. maybe with the veriable valve timing the port changed? still you would think that the titan would be the same as the QX.

 

[LoseMyMind]

he told me that the next one i get will be just like these because they are made to fit the QX.

 

[LoseMyMind]

What I got out of the email is that DT is no longer making the oval design because they are trying to make the headers fit both the Titan and QX with the same part. Maybe the holes are elongated so that you can make them fit on both. My problem is there is absolutly no way to know if you have it lined up properly. I have tried re aligning the drivers side about 8 times. My passanger side is fine.

 

[LoseMyMind]

I had the same thought but when I went to do it I ran into two issues.

1. I still couldn't tell if it was lined up even when I had the header out and the gasket on it.

2. The 1st, 3rd and 4th port holes are just too big. I have yet to see the second port leak because its small enough that it works with the gasket.

I wish I could just get a new one that would seal up. I bought these because I had cracked manifolds and they leaked. So the whole reason I bought these was to fix my exhaust leak and I am yet to do that.

 

[LoseMyMind]

They keep saying they will replace it but Nick keeps on telling me I should send it back to be fixed. I also never believed he was out of them in the first place. I think they are dragging their feet to be honest. Monday will be 5 weeks since he told me he would get me a new one. I asked him yesterday to give me a date I can expect my replacement and I have not recieved a response.

 

[LoseMyMind]

I bought them from DT. They are brand new.

I did not say anything negative about you or the headers. I was just talking to people on here who are always helpful. If not for this website I would never have even known DT existed.
I bought the headers from you and they are very nice. I think I got a good deal and they really make a night and day difference on the truck. When this issue came up we agreed on a solution to the problem. When I spoke to you yesterday I didn't really feel comfortable with the "if you don’t want to send it back to get fixed then you can just hang out that’s cool to" comment. I was hoping I would have a timeframe to expect a replacement. My only issue with time has been the time my truck would be out of working order when the header was being repaired. All along I have said I would wait for a new one.

I don’t want anyone on here to get the wrong idea that this is a gang up on the manufacturer thread. Nick has been in contact with me throughout and has not gone back on anything he has said. I also told you I was on here so you knew I wasn't trying to bad mouth you behind your back. Maybe I shouldn’t have said I didn’t believe you but I really didn’t. That being said I understood that you may want to wait to replace mine until you had some more made up. I figured if you only had one or two sets giving me one might not be the best idea in case someone called to order more.
If I upset you in any way I am sorry it was not my intention. If anything I wrote was false or if I made any comment that wrongfully put your company or you in a bad light let me know and I will take it back. I cannot control what everyone on here says.

Anthony,
No worries man! I do have a run of the modified ports due back next week from ceramic OR I am having them do a run of the conventional stainless oval port design due in approx 4-5 weeks. I have the conventional "OG" design mild steel versions in stock now.

Nick,
Do you think I should wait to get the conventional oval design? Or do you think the new design will work?

 

[LoseMyMind]

BB Thats a damn good idea. I wish I would have thought of that yesterday. I wonder if the stealership will even have that gasket.

 

[LoseMyMind]

Shouldn't it be the same on the 2011 QX?

 

[LoseMyMind]

Its going to be 2 to 3 days before they have it. Its 31 bucks.

Donson,
I can get Nismo's. Let me know if you really want them.

 

[LoseMyMind]

I took a straight edge to it and looked for light passing between the flange and the edge. It didnt look bad to me. The head side has not leaked once so I dont believe the head has any burs. I agree with BB. I think the ports are too large for the crush rings on the gaskets but I could be very wrong. I confirmed with Nissan and Infinity that the new 2011-2012 QX has new round exhaust ports on the head so the gasket should have the rounded crush zones. We will know by friday if the gasket will work
