In my search for speed, I noticed that the only headers available for the Armada were the JBA's, they also have an exhaust system for the titan, but nothing listed for the Armada. Thats when it hit me that JBA is located close to where I live. So I called and spoke to one of their managers about test fitting an exhaust system for the Armada on my car. He seemed very optomistic about producing a system for our vehicle. He said that in a few weeks when their R&D got caught up he would set me up with an appointment to get fitted. Of course for being the donor vehicle, I will get a free exhaust system, plus he said he would give me a good deal on the headers, and install for them :D. Note: to install the JBA headers you must weld on to the existing exhaust.

I don't want to be to optomistic, but hopefully they will follow through. This also gives us a great chance to give them feedback on what is most important to us in an exhaust system. The manager was wondering if I though Armada owners would perfer a stainless system, or an aluminized. I thought that I would pass along any prefrences to him. It seems like to most people the cabin drone is one of the biggest factors in their exhaust purchase.

I will post back when I get an appointment set up for the fittment.

I am in the market for a cat-Back.....
I would be willing to take ss or Alum....
And Drone would be the biggest issue and of course the dyno/performace is probably the biggest factor.

Just do it.

I am hoping to work that in to the package. Well see if the money permits.
If they give you push back, then sell it to them. Tell the, they won't get the sales they want if they don't have the data to back it up. You can go to the corner muffler shop and get a customized exhaust.

If they have a dyno, which I bet they do, it would only cost time and a little electricity. They should include it. If they don't have one, I'm sure they have a deal with someone to use one. Again, get them to foot the bill. ;)

Might be worth it?

I don't want to discourage you but the cast stainless steel exhaust manifolds are really pretty good pieces for OEM. I would guess you might see slight gains, but not like the numbers you see replacing other manufacturers restrictive cast iron manifolds. The stock Nissan 5.6 does not make all that Hemi killing power using restrictive manifolds. And they don't leak like most headers do within 50k miles.

I agree. I don't think their headers will do anything. Most people with them say they do nothing. But hey, they can't hurt, and they are free. Just make sure you get ceramic coated so they stay nice and shiny, don't leach heat, and last longer. If they say they won't pay for the coating, pay for it yourself. Well worth it. ;)

The stock manifolds are very good. They are welded stainless, not cast, and are high quality. I don't headers like the JBA will help any by themselves. Most people make other changes when installing the JBAs, such as removing the rear cats and installing a new exhaust system. I think you will see the same gains if you made the same changes, but still use the stock manifolds.

On other forums Titan owners have been very disappointed with JBA's shorty headers. They are not seeing any power gains on the dyno and no drop in quarter mile times or increase in trap speeds. It is probably going to take true full length headers to produce any real gains.

Custom full length headers have appeared on SCORE (Baja 1000) Titan trucks and may someday show up. I'll wait until then and stay away from the shorties.

If you can get them for free, go for them, but please dyno before and after.

We'll see about the headers, I have read the posts over at CT, but really I didn't find a whole lot of conlusive evedince over whether or not they were making gains. I will have to continue thinking about it. :confused:

Well I am finaly getting the JBA exhaust! :)
Took the 'Mada in last week for the test fit. They kept it for a day and a half. John over at JBA Headers was very helpful, and friendly. I let him know about the drone concerns that many of us have. So they test fit a few diffrent mufflers to see which one worked, and sounded the best. The kit will only be available in SS I believe.

Tomorrow my wife will drop off the beast at JBA Racing to get a dyno done, and the exhaust installed. She gets to have all the fun, while I work :D . Oh well, I am excited to see the results. I have decided to postpone getting headers for now, if I get them later I will be able to see if they maKe any gains over the stock ones.

I will try to post pics and video when its all done.

See if you can get them to make it dual, and I'd like to see the tips pointing outwards to the sides. Better for towing, etc. As for headers, Stillen just came out with long tubes. Those will make power. ;)

No duals from JBA, it will be a single side swept exhaust coming out in the stock location. Gibson I believe has a dual system though.
So does Borla. I just would like more options. ;)
