JBA Long Tube Headers Review & Install Instructions

No rasp above 2k?

The dtlt, urd y, urd 3" exhaust has terrible rasp n/a imho and many others.
what magna system did u get?
Mine sounded like it had a massive fart can on a civic imho.....sounds like u got a better muffler.....size/part # would help others possibly

I know with the urd 3" system, many ppl run 2 mufflers or a resonator.

Do u have sound clip?

 

Excuse my ignorance, but the stock manifold looks relitively efficient. Has anyone just deleted the cats and compared those gains to these since would be the fairest way. I'm debating on cutting the back two cats out my self is why i ask to see what gains are to be had if any.

 

anyone have an answer for the aforementioned question about the cats? i did see a write up by chris4x4 i think, on scavenging, and how everything in the stock exhaust is harmonious and such, but it would reduce the back pressure quite a bit to remove some cats and as long as the pipe size and shape is the same should be beneficial in theory.

 

Hi, I know this is an old thread but I hope you are still getting these posts.
I just had a manifold cat go bad on my 2006 Tacoma. I replaced it with the MaganaFlow direct fit unit and my truck still has the inefficient cat code.
I paid $557 for the Magna flow and then I find out I can get the same set up as you for less money (and BOTH) sides. O'Reilly's say they will take the MagnaFlow back so I'm getting the JBA long tubes.
My question: have you noticed any heat problems from the headers and would you pay $90 more for the ceramic coated versions if you had to do it over? (URD says ceramic coatings reduce the radiated heat).
Thanks,
Randolph

 

If you plan on getting the long tubes, get the URD Spec-U. Much better gains and sound from them. I have posted the dyno chart in a couple posts. One being in my N/A dyno link in my Sig.

 

Out of stock and I have to install something now since I have a bad front cat

 

Hello if anyone is still reading this. I got the JBA long tube, SS, ceramic coated headers installed last April after a lot of swearing at the tight fit.
I installed the "URD Dual Rear O2 Sensor Simulators" also.
I still get the Check Engine code and my gas mileage dropped from 18-city, 21-highway(best recorded) to 15-city and 18-highway.
It has been that way ever since I installed the headers.
Any ideas?

 

What is the specific code number?

Have you visually inspected around the flanges for soot deposits? That would mean either your hardware is loose or your gaskets are bad.

Did you make sure to have the o2 sim properly installed? One plug wire is long whie the other is shorter. The must be installed into the proper side or bank.

 

I didn't write the code down. I will get it read again tomorrow and post back.
There are no leaks anywhere.
Since it has been several months, I don't remember where the long and short wires are. I can inspect and find out.
Which is the proper side for the long wire?

 

Don't quote me, as I only remember that they are length dependant. I think the long is on the driver side. You should contact URD and verify to be certain.

 

Thanks. I have contacted them. Waiting for reply. They answered my first question overnight.

 

Is the code p0158? That's the code I've been getting since I installed my Urd o2 sim

 

I don't have the code yet. I just today had time to disconnect the battery cable for 15 minutes as URD suggested. I will get the code read when it comes back (as I assume it will again).

 

I was looking for a sound clip. Did I miss it somewhere?

 

Bump

 

Just got my jba long tube headers in and they came with the 02 bung plungs

 

Any updates on the check engine light issue?

 

What year is your truck?

I think it’s only 2015’s that have issues with the sims.

EDIT: disregard, I looked it up in your build thread.

 

Does anybody ever run JBA shorty headers, I like the whole idea of long tubes but the headache of throw lights and codes seems a little much and also annoying. I currently have a K&N 57 series C.A.I. with the URD M.A.F. recalibrator sensor, URD Y-PIPE, and a Flowmaster super 44 3" cat-back system. Any info on anybody running shortys with a similar setup please let me know, have a good one yall.

 

I’m running URD headers with zero issues.
