Just looked at their site and it looks like it’ll be fine. They have some more information on their instagram page.

Looking at their site made me realize… those with a 1.8L are really gonna get shafted by the aftermarket tuners since for tuners the 2.0L is more desirable.

 

You'll probably through a cel, too much will change in terms terms air flow stock vs 2j.... if the upstream doesn't catch it right away the downstream will

BTW after a little while the extra air flow will start to blow out your muffler on the stock exhaust and it'll sound like angry raspy bees (garbage) ... I would advise at least getting a muffler in the near future.

As for the cel ... if it's too early to tune for you then try a defouler, I've never tried this on the wideband o2 sensor tho so I'm sot sure how well it'll work, they work perfect for the downstream o2.

 

Thanks for the info bro. I just don't want to see that CEL on, that's what's bothering me right now and thinking whether to put it on or not or just get a muffler. 2J racing told me that they are working on a catback muffler for the sedan so I wonder how is that gonna look.

 

I don't think its a mistake, were you never planning on tuning? If it's just the cel that's got you worried then you could at least try it with a defouler ... maybe someone else on here who has the header has more insight.

 

I have an order for the 2j headers right now. From what I've read it shouldn't throw a CEL. But like what was mentioned above just get a defouler and it should be good.

 

Questions on 2JR Headers and Drive-Start Control Malfunction

3 questions please 1. Just Installed the 2JR headers and they sound and feel awesome, but I got a CEL. No big deals from what I’ve heard but has anyone found a solution yet to get rid of it? 2. Ever since I got the headers I got a “Drive-Start Control Malfunction” but the car is still driving...

I'm going to think about it guys and thanks for the help. The guy over 2J racing told me that their Corolla HB has not gotten the CEL on but that there are some ppl that do, anyways he recommended AMT tuning.

 

Well I received my headers yesterday so I'm going to order the defouler from 2j racing and take my car to my friend's shop. They look beautiful in person btw 😁

 

wow. those are pretty.

 

Yes

Yes they are bro, thank you 👍

 

Gonna need a sound clip comparison for these too. I don't get mine till like January

 

I'm still debating whether to put it on now or wait until I get the midpipe or catback but I'm sure that is going to sound nice bro 👍

 

man that would be cool if they made a high flow cat version. i really like the looks of that one.

 

Well their midpipe has a high flow cat instead of stock gpf so combined with the header you'd have a normal setup hf cat / res / muffler.

 

Currently running the header and mid pipe hks exhaust coming oct. setup has a defouler on the mid pipe so bank 2. Throws a cel. Reset the ecu and code reappears. Will update on if the cel is bank 1 or two.
Bank 1 will be due to the primary on the header and bank 2 on the mid pipe.
If bank 1 a tune is required with the header.
Other mods are injen intake

 

I'm going with bank 1 upstream if you're running a defouler on midpipe man, I rarely have cel on midpipes that defouler doesn't fix, plus since it's not wideband it'll never mess with the afr

Edit: there are a couple of angled and shorty defoulers you could try on header but like you said tune is obviously optimal.

P013A stands for “O2 Sensor Slow Response – Rich to Lean (Bank 1 Sensor 2).” It is logged once the PCM perceives that the post-catalytic converter oxygen sensor (Sensor 2) in Bank 1 is responding slowly. ... Oxygen sensors use electric signals to communicate with the PCM.

so either a leak,

Hello,
First time posting here. I have the 2J Headers, 2J Midpipe and the Borla catback. So far all the defoulers I tried give me a CEL (the one that came with the mid pipe low profile, 2J 90 degree one & one 90 I got froma muffler shop). Currently im trying the vibrant J defouler with the mid restrictor and lasted almost 6 days until I got the P013A code. Im going to try next weekend the smaller flow restrictor that came with the vibrant defouler and see if it helps at all.

FYI, after every code even if I clear it with my scan tool the car doesn’t run the same. Less responsive and hesitates. Ive been unplugging the battery to reset the ecu.

 

clearing the code won’t do anything. It will eventually come back on. The car will be sluggish as the readings from the defouler O2 sensor are slow as you have spaced it further away. First sensor is for A/F ratios, so that sensor reads High or normal, than the secondary shows a lot less. That’s why you will throw a code.

As I stated, you need a tune. I wanted to see if their statements were true, but with ever catless header, you will need a tune as you will throw a code

 

Hey anyone who has the header... what's the I.D. difference vs stock at the engine side and outlet to midpipe?

Thanks in advance

 

I did not do headers. I did 2J Midpipe and Remark Center Catback exhaust. Got no CEL.

The Midpipe tells you to "cycle" the car with driving conditions so that the ECU can adapt to the new conditions with idle, slow driving, and multiple shifts first before hitting it hard. I did the Catback months before the Midpipe so that may have helped the ECU learn over time with incremental installation/differences. The Midpipe did come with a defouler plug to help prevent CEL. Not sure how they would recommend installation, but you may call and ask if you should do a "one step at a time" method to let the ECU learn in steps rather than doing it all at once.

The midpipe is much more important than headers, IMO because it has the cat and also there is a restricted chokepoint on the stock midpipe where it goes down to a smaller diameter tube size near the flange. I would recommend getting the midpipe in addition to the headers, as it doesn't make much sense to just do the headers with stockfor the rest after it, IMO.

 

Did you used the defouler on the midpipe with the stock headers?

 

Yeah, it came with the 2J midpipe. I think the headers may change a lot of how the sensors read and may cause the CEL.

 

Interesting… I wonder why you should use the defouler if basically nothing is changing as far as distance from 02 sensor on the headers and the second sensor. Diameter before the second sensor on the OEM midpipe is almost similar compared to the 2J midpipe. Thanks for the info! I’m planning to change my headers and put the OEM’s back.

 

Not really sure. The Defouler/sensor is before the Cat and Resonator. I am sure that 2J tested it and determined that it needed the defouler to work correctly for some reason. Maybe they assumed they needed it for the combination with the header so engineered it for that option instead of making 2 versions. The owner of 2J specifically said to install it with the defouler first to prevent CEL.

 

The defouler will offset the sensor further away from the exhaust stream.

Is your upstream o2 sensor a wide-band or lamda sensor? If it is, then over time, you might get cel for slow response or no activity.

On my speed 3, the upstream is a wide band narrow sensor. I am getting cel for downstream o2. It isn't able to send the signal back to the upstream and the ecu. Even with a defouler, it didn't help me.

I tried to modify my downstream in the hopes of it being able to communicate with the upstream o2. Instead, it has turned on the maintenance light and also causing other sensors to throw off AFR and boost readings. It's weird. I'm removing it this weekend and going back to the unmodified one.

Cobb access port - speed3

 

Yeah

 

I had the same issue with my Civic, there was no way to do the midpipe without a tune / disabling the secondary o2

I didn't actually change the bung at all on my midpipe only modified after the o2 maybe I got lucky? Its been 18,000kms no tune no defouler no issues ... yet? Lol

 

Mines just being stubborn.

 

Ha, was that like an electrical ground issue?

Never would have thought anything like that could happen.

I'll never really know. I just know that only one ground wire was disconnected. The ground is on the passenger motor mount.

I have another speed 3. Just did a valve cover gasket and plugs. Now it has high fuel pressure in the rail. This one's biting me. Can't figure out why the pressure is so high. Checked all connectors for broken or bent pins. None found.

 

Anyone with this header, how are the welds holding up long term. Ideally if you live in Canada that'd be perfect for my climate conditions lmao.

But seriously any feedback would be appreciated - thanks.

 

Anyone running the 2J header with stock exhaust. I can’t find any exhaust for Corolla Cross. I have ordered the AMT stage 3 tune, camry throttle body, GGP corolla to camry throttle body adapter and GGP EGR delete (half). I am currently on Shell 93. Only installed part is the AFE Takeda Momentum 5R cold air intake.

Have you tried asking on the Corolla Cross forum as this is the sedan/hatch forum? Maybe someone over there has your answer.

Corolla Cross 1st Gen (2022+)

Should've probably researched that before you bought all of that.

your cat is gonna peace out in like 3 months lol

 

I’m pretty sure it’s the people with the P&B that will have that kind of issue. I ordered Stage 3 (without the P&B option) I got governor delete, EGR delete and park/neutral rev limited. In my opinion, P&B does not provide any performance gains, I clearly do not understand why people do this.

 

Just an update. I ended up getting custom axle back exhaust done recently. I plan to get the 2J header after winter. How well does the header work with the stock midpipe. I just want the cat out but don’t want too much noise. I’m on AMT Stage 3 tune with the camry tb, ggp tb adapter, afe intake, ggp egr del, jet performance maf. My appologies for posting in the sedan/hatch tread but no one is modifiying the cross. Essentially the same platform as the sedan/hatch so here I am.

 

You need a midpipe more than you need a header... Forget about the header. Just get a 2JR midpipe.
