I don't own either but make sure you do a search for Doug Thorley on the board. There is a pretty interesting write up by a person who had some issues with a product on here. I think every business has a bad day, but it is not so much the complaint of the customer that bothered me it was the representative and the way he handled it that did...and more than one comment. I would link it for you but I am on the mobile app and I don't know how to do that 
This is a great place to ask around though!

Well I did see another forum member had a write up about the DT headers rusting on him and he would have to send them back in order to get new ones, but If he threw out his stock manifold he'd be kinda screwed. But some customer service is better than none I guess..?

Ceramic headers!!! Shield heat better and protect against rust. 2 common enemies of headers?
I got JBA's hearders put on at a JBA performance shop here in San Diego. I felt comfortable knowing that this company had a professional history in performance and racing. Which might not be so intuitive as the name Doug Thorley.

I have DT exhaust and yes they do have rust on them, but besides a little rust I like them a lot. The fact that I go wheeling so much and that the exhaust would be in mud and water all the time, I basically knew that it would rust for that reason so no surprise there. It was the first mod I did to my car and I was happy with the choice. From what I've learned is don't get the Long tube headers from DT.
Here is my Exhaust video I made a long time ago

I have had my DT headers on for quite some time and I really enjoy them. By the way, no rust on them to date!

Has anyone dyno-ed after installing the JBA headers?
Shorty or LT'S?
If you are speaking on LT's then just look at ANY DT dyno graph as they are the same exact header set. We saw 11rwhp and 16rwtq with the JBA shorties on my truck on the dyno.

Can you elaborate on the quality differences? Aside from varying grades of stainless thats the only major difference I see between the two.
I will say that JBA has been very good to me. I put mine on about 4 years ago, they broke numerous times, about a year ago they replaced them and charge me 1/2 price. They also designed my exhaust system with magna flo muffler. I have great performance from my truck, run 35's and pull a trailer, due to the exhaust system I think. Plus it has a great sound.
Draw back though and all of the California people shoud be aware. They are not legal in California, they say they are, but they do not have a number stamped in them. I learned this last year when I was fighting with Toyota over my cats going bad.
I was told then that they were still working on getting them legal in California. Maybe by now, but if they do not have a number they are not legal and will fail smog.
Not good news for a lot of us I am afraid, I have to smog mine in November.

I also have them on sale...
This is why I pay the big bucks to advertise here... so excuse the shameless plug.
I also have the JBA on my FJ and still love them after years of abuse!

I also wanted to say the bad cats is not a new issue. Many Tacoma owners I know, that don't have JBA headers, have also had this issue. The most recent case of this I heard was from the body man I knew at Peace Arch Toyota. He was pretty non-chalant about it though, he got great prices from his dealership on the cats and labour... When he said "great" he had a huge grin!
I like the headers, and no they did not cause the cat failure, but they were the reason Toyota said no to replacing the cats, and I did not get a great price, I got screwed badly, did not have it done as Flow master says they will have CA approved cats before I have to have them. Trust is my only hope
Again for those that have them, no number stamped on them means they are not legal in California. If these new ones have a number they are good to go. I was told when I bought them they were CA approved, it is stamped on the headers, but they are not. Great to hear they got it done.

JBA has a CARB decal just like all other companies. I would call them and see if you could not get a decal for your JBA headers. The decal has the part number stamped on the flange of the headers and the CARB number.:cheers:

Yeah I am fighting Toyota right now about bad cats... and there are basically no rules where I live. No smog and no safety inspection might mean time for an upgrade in headers.
I guess in California it is a welded on tag with the number imprinted in the tag. I have the tag, just no numbers imprinted. Not going to worry about for awhile. I think I can have the guy that built the sytem get it fixed for me if Flo Master gets theirs done.
