Guys I hate to say it but the JBA headers we have now are making 20-25hp same as AFE is claiming with those $1500 headers. Hmmmmm
Never heard of that with JBA headers. Sold a many sets and 99.9% are tickled with the product and gains. For the price you cant beat it..yuppers!
although you may have to reweld missed weld marks, make sure to shine a flashlight thru them
probally was just my luck, but for the price and having a welder at the shop. I was still happier than a kitten with tuna sprinkled with catnip! :eek_surprise:Never heard of that with JBA headers. Sold a many sets and 99.9% are tickled with the product and gains. For the price you cant beat it..
I am on the same page JB, Even with boost I don't see any significant results unless the exhaust side of the head is flow match ported. Flow is flow and the bottleneck is the head.:nerd:The guys who will want the 1-3/4 x 3'' are the ones who are using forced induction, nitrous or even adding cams and so on.
There is nothing wrong with the current JBA 1-5/8 x 2.5'' headers for 99% of the Titan owners whether its for performance or most importantly a budget friendly solution to fixing those bastard OEM cracked manifolds.
There will need to be dyno testing on stock and modded Titans comparing both JBA 1-5/8 x 2.5'' vs 1-3/4 x 3''. This stuff takes time and money.
Damn, gonna make me spend like $2000 on the new Armada before it's got 2k miles on it with porn like this...Here are the Kooks 1-7/8" x 3" headers for the VK56VD found in the Patrol/Qx80/ Armada and new Titan. It as been verified these headers do fit in the new Titan.
American Racing Headers, also for the VK56VD in the new Titan/ Patrol/Armada and QX80. These come in 1-3/4x 3'' or 1-7/8 x 3''
And... for the VK56DE 1st gen titan and armada guys... AFE POWER is now making headers for us... Supposedly wont be ready until next month.
aFe POWER 48-46107-YN Twisted Steel Header & Connection Pipes; Race Series | aFe POWER
Looks like there are some harness extensions in these pics...
Lastly, JBA is going to be making a 1-3/4 Header for the 1st Gen Titans as well.
So.. NO... Doug Thorley isn't the best option for the VK56DE nor the VK56VD.
