JBA headers vs. Doug Thorley Headers. Which is Better? - Page 4 - Toyota Tundra Forums : Tundra Solutions Forum

We have a lifetime warranty. That speaks for itself! It is not about skimping it is about our desire to make a top notch product while maintaining a competitive price point. We use extremely thick 14ga mild steel rather than paper thin 18 ga 409ss. Ceramic coated thick wall mild will retain much more exhaust heat than 18 ga ss will. Also thick wall is much more resistant to cracking than 409 is. That is why we choose to use it. As fas as pricing is concerned 14 ga mild is the same price as 18 ga 409 if not a bit more. Than add in the expense of the ceramic coating. The biggest expense of our headers is keeping them 100% AMERICAN MADE. Most of my competitors CANT say they are! If we did use over seas or south of the border supplies than heck yeah we could make a less expensive header but it would be junk. Oh yeah and our headers are NOT aluminized like it was said above. And 409 will rust just as fast as raw mild steel.

Although I appreciate the presence of a manufacturer on this board, I disagree with this statement.

Burg,

Just realized you quoted me, sorry for the late response.

I was thinking about adding the MAF sensor calibrator from URD which is the same thing I put on my 4Runner. However, with the advent of the supercharger looming, I'll probably just wait for that to come around.

We'll see though...

Where You At Thorley????????????

No, I don't think he was.

Just picked up a set of DT headers for my 06 DC 4x4 Tundra. Just want to say that the build quality is very impressive. Nice welds, thick flange, tubing, collector and a sweet ceramic coating. Very solid feeling headers. Not looking forward to the install though.

The Dt headers I'm sure are well made you can see from their pics that they are and nobody has complained about their build quality. Mild steel may not crack as easily as thinner walled 409ss but it sure won't offer the rust protection that the 409ss will especially given the fact that Jba's are ceramic coated also. I have had several ceramic coated mild steel headers on muscle cars and over time they will start to rust through the ceramic. I have never seen this happen with stainless. 409ss also tolerates the heat better than 304ss and I personally have never seen a header crack that was built from 409ss unless it had a huge turbo hanging off of it. But really the main point that I wanted to make is that the Dt's really only make power at a small part of the curve and not throughout the powerband. Yes the Dt's might have higher gains in the low to mid range but the fall off to almost stock power levels at peak. The Jba's seem to make more consistent gains throughout the powerband as well as adding good horsepower up top. I guess we will have to wait to see the dyno's that get done independently to see if the Dt can prove this wrong.

I found ceramic coatings to last maybe 50% longer than a good sandblast / high heat rattle can job before installation...typically by the end of the second season the rust is visible. Considering ceramic coatings can inflate new header costs quite substantially, they are not worth it IMO.

I have a set of the DT ceramic headers on my 96 Tacoma 4 cyl and after 1 year they still look good. No rust but the silver finish has changed to more of a white color.

I have jba headers shortys looking to gain even more horsepower so Im thinking of buying doug throley long tube headers any suggestions are long tube headers illegal in california
I also heard that my cats would have to be removed ?

Everything is illegal in California that matters. You can marry your uncle bob and you can grow pot on your back porch but if you buy Long Tube DTs for your truck and even think about an AK-47 then you're an SOB and have to leave the state. (but not before you pay a fine.) Sorry, to answer your question, Long Tubes are not Kalifornia legal except off road.

Have my doug long tubes, I just need to put them on. I plain on moving the o2 bungs back behind the second cats and moving the second cats right up to the collecters. hopefully I wont get a cel. i had to go order a longer o2 sensor,wow 135 dollars for that little sucker i will keep you posted on how they turn out. Im hoping that the sensor comes tomorrow, then i will start the mission.

I wondered if this could be done. Seems logical.

Long tubes are in and cats moved forward. I ordered the passanger side o2 because it is longer then the driver side. Before i did this I went a week with the sensors switched and found out that no CEL came on. So I ordered the sensor and put on the long tubes on and so far no CEL. I have gone a bout 100 miles and so far so good.
