JBA long tube headers

07 rcsb, 4x4. Truck threw a P0430 code the other day. Turns out my front cat came loose and is rattling around inside the pipe. Silver lining: I can upgrade to long tubes, get rid of the front cats, and install O2 simulators.
Eventually I want to get it tuned, but are there any risks with running the new headers with the TRD supercharger tune? They are jba titanium coated long tubes if it matters

 

@dirtydeeds

 

I’m happy to help. Give a call tomorrow?

760-877-4234

 

Thanks for the offer.

 

Additionall does anybody know the material specs for the JBA midpipe extensions and the factory midpipe extensions? for welding purposes (choosing the right wire)

 

Use 308LSI

 

Is the general consensus to use the JBA gaskets for install? Seems the Toyota ones would not fit well due to the raised faces on the flanges. I mean they could work, but the JBA seems like a better design for this application. Just don’t want to waste any money at this point.


Is there no gasket for the V-Band interface? Is it just a metal to metal seal?


And for the air tubes on each side (small diameter tubing), is there another gasket needed for that?


Just trying to get any additional parts needed.

 

Use jba gasket and tighten down with 12mm box end with all your might!!

Use Grey high temp etc at the v band. And install the o2 sensor in the primary, not the collector.

Use the stock gasket for the air injection flanges. And use a thin layer of etc on each side of the gasket.

So if you install long tube headers you don’t run the cats any more?

 

We can build mid pipes with the following options:

Non catted
One set of metallic core cats
One set ceramic core cats
Two sets of the above
Or any combination of your cats(you would just have to send them to us)

 

You have to either
-cut out your front cat and weld on a flange extension to your existing mid pipe (coupled with and O2 simulator)
-Get a custom setup from Dirty Deeds
-Get catless midpipes from JBA (offroad only)

 

Can't go wrong with Dirty Deeds. I've personally spoken with Keith and dude is legit. Awesome guy and company!

 

What are the differences between metallic core and ceramic core? Pros/cons?

 

Metallic core lasts longer but doesn’t clean up the exhaust enough to keep the check engine light off.

Ceramic is cleaner. But aftermarket ‘wears out’ really fast and the light comes on pretty quick anyways.

Best cats to use is stock.

 

I have the Ultra Copper, but it looks like Permatex also has the Optimum Grey that has the same temperature rating, but a few extra added benefits of vibration resistance and high torque application. Should I pick up the Optimum Grey?


Also, why would you put the sensor in the primary tube and not the collector? I don’t know much about these things, but the OEM one is in the “collector” and not just one primary tube.

 

Yeah in those, uh, questionable states

 

I use the grey. Used to use ultra copper. But the grey is the new badass thing

The primary is fine. And if there is a slight leak in the collector you get surging at idle. And afr is off a little bit.

 

Work with Keith to have best possible outcome. Period.

 

Just finished this beast. Holy hell what a job.

 

Couple points from the install:

• Yes you need every iteration of 10/12/14 mm socket/ extension/swivel
• No I did not need to modify or bash my floor in to make these fit. They didn’t just slide in either. It was tight. But at no point did I feel I would need to modify anything.
• Used 309 mig wire to weld the extensions at the rec of the weld engineers I work with and what JBA recommends.
• Def soak the hardware with penetrant the night before.
• Not a fan of the JBA v-band flanges. Needed a decent amount of high temp optimum grey to seal.
• Put the sensors in the primary as dirty deeds recommended. I’m not sure the connectors would reach if installed in the collector.
• Recommend to test fit the fittings/ sensors in the headers prior to installation. Especially if they are coated. It adds thickness to the threads and makes installation more difficult.
• Steering shaft gets in the way, but flexes more of you loosen the coupler screw.

 

That sounds reasonable^

 

Well we pulled my transmission out for a full build and had to yank out one of the headers. Damn JBA gasket showed leaks on it!! Now Im strongly considering the oem multi layered steel ones. Looks like the primary tubes would seal fine but the smaller (emission?) tubes were slightly questionable. For those that used oem gaskets with JBA, did you supplement the install with any permatex grey at the head interface? Or just go on dry?

 

I use jba gaskets on the main flanges. And just reuse stock gaskets at the air injection ports. Just use a little permatex grey on the stock air injection flange gaskets.

Main reason jba gaskets leak is they’re not tight enough. You have to compress the gaskets all the way so when they’re heated they don’t compress more.
