wagner header blew welds!

[Subghetto]

Wagner's a good guy. If a weld is faulty he'll fix it for you. No need to bash another vendor and potentially run them away.

p.s. I've worked with Wagner in person. The dude welds like nothing I've seen before. This could've possibly been done by another of his employee's. In ither respect he does good work and makes quality items.

p.p.s. as for his design, he mad more power at the wheels WITH the stock emissions equipment than OBX got with their 4-1 header that removes the cat. Obviously something in his deisgn works well.

Yeah no need to bash vendors on here I hate when people do that unless you get scammed then I see no reason too. Anyway what matty says is true if you check the thread with the dyno day at MAM mazdateam you see that the header put out some sweet numbers. The problem is if you got the mild steel header it will not stand up the same as the ss header that's why it's a lot cheaper.

Do you have the mild-steel or the SS header? because I have the SS header and I have'nt had any problems at all. Oh and Andy is a very cool guy just tell him what happened he always tries his best to help out customers.

mild steel

i'm not bashing at all. i was just a little upset to see how bad the weld had come apart. i was very happy with the gains and quality, and i'm sure this will get resolved. its just frustrating when parts fail. we all know that.

when i was talking to wagner about purchasing the header initially i was told that there was no difference in the durability or performance of the two, just that i might want to heatwrap/jet-hot the mild. which is why i got the mild, figured it wasnt worth the extra 100 for it to look a little better. power > looks, less money spent > looks

 

[Super Matty P]

I wasn't talking about you.

 

[wannabe]

i gotcha.

 

[wannabe]

i got a message from joe @ wagner motorsports yesterday, he said to just send it back in, and they will fix it, or replace it. so that sounds promising.

does anyone know the part number for the gasket that goes between the manifold/shorty and the pre-cat? mine blew a while back (as i stated in the first post) and the one in nate's setup was also blown. i'm wondering if i can just use exhaust silicone and make a better seal with that anyway.

 

[Super Matty P]

the gaskets between the manifold and precat are metal...I wouldn't try using silicone on something as hot as that.

 

[wannabe]

even the exhaust silicones? i thought that was there job?

 

[Super Matty P]

i've no experience with "exhaust silicone".

 

[flat_black]

Nah, exhaust grade silicone only handles up to 500 degrees... That'll be seeing upwards of 1300 degrees, most likely, so it won't hold up to much. Some copper gasket sealer spray may work. My suggestion to you is to take the manifold/precat apart, clean both sides of the metal gasket, and both mating surfaces with Scotch-brite or some similar scrubbing product, clean them off, then use a thin coating of the copper gasket sealer on either side of the gasket. Torque to specs, then a little more, drive around for 10 minutes or so, stop, and retorque.

Here's basically what I meant, before, and after. =)

Idealy the second design is better in that you don't have the little piece to worry about. But from a realistic standpoint, it isn't practical. Its much more difficult to make such a design and that equals more $$$ needed. Also from a flow point of view, round pipe is always the best for the flow of gases or whatever. It creates less turbulance. By going with the second design you create a greater amount of turbulance at the center. But nothing probably measurble by our standards.
Anywho... best solution in my opinion is to stick with original design... just beef up that center piece.. make it thicker and weld the b**** from both sides.

Thanks matty... well said!

so i have the header boxed up and ready to go back. hopefully it wont take too long coming back.

The second design I offered up would be more expensive, thanks to it being something you'd have to do by hand.

However, as far as turbulence is concerned the first (original) design is worse, for the fact that since there's an immediate lip, and that gap that simply 'exists' where the tubes form, that would cause a low-pressure zone, causing tumble through the whole of all four of the exhaust streams. The tubular design is good for velocity, due to the fact that you're keeping the flow in a constant volume. As the gasses converge, however, the volume of gasses is not only increased, but it's going into a larger volume container, anyway (The collector, or in this case, precat housing), so the volume argument is pointless, really.

The T design isn't monetarily efficient, but as far as laminar flow is concerned, it's more efficient in design, honestly.

Good point... didn't think about the low pressure zone that would be created at the exit. Oh well.. both designs have their perks and their downsides.
And about laminar flow... its not happing in those exhaust pipes. There is turbulent flow like mad! But I understand what you are getting at.

 

[wannabe]

honestly though, the header gives plenty of gains. however it works is fine with me.

 

[fLyPiNoY7]

should i send in mine?...its not as bad as mp3wannabe's problem, but i noticed a few small cracks at the end of the header where it connects to the pre-cat...

 

[wannabe]

mine is finally coming back to me today. so if you cant live with it, you can send it in, just dont expect it to come back quickly..

 

[Kooldino]

hopefully this will get resolved quickly...

Don't bet on it.

update:

i got the new header over a year ago, but guess what...the new one is having THE SAME PROBLEM now....

i'm pissed...
