JBA has been building and testing headers for the 5.7L HEMI since it was introduced in 2003. With this experience our engineers were familiar with the design and flow characteristic of the heads and knew what the engine would respond best to. The engineering team at JBA addressed the critical short comings of the 5.7L HEMI exhaust manifolds with a fresh design that started with high flowing 1-3/4" mandrel bent stainless steel tubing. By giving each cylinder a smooth unrestricted path, back pressure is reduced and flow goes way up. The giant 3" collector was engineered using JBA's patented FireconeĀ® - a unique directional device similiar to what you find on a long tube race header - which improves flow by providing efficient scavenging of exhaust gasses. Other standard features like thick 3/8" CNC laser-cut flanges, O.E. style JBA sealing dome connection to the exhaust and high quality hardware make them a highly effective upgrade for the HEMI. Bolt-on a set and feel the JBA difference.

Very interested....Will wait for Dyno results. How much for shipping to Southern Calif?

 

I see a lot of BS I want to see real #s from dyno and not real wheel to crank fake #s . What I see in the Pics will not give you more than 2 or 3 hp. They need to be a Tri Y or long tube.For data feel free to call 800-251-1505-ex 102 Thanks Rob

 

Hello 2avoid2 (Rob)

What is BS other than your statement of "what i see will not give you more than 2-3 hp".

Here is an idea, do alittle research before you speak up on a subject you know nothing about.

I have heard nothing but rave reviews from all Magnum / Charger / 300C customers who have put these on.

Since you are such an expert, why dont you put a set on your 5.7L Hemi LX car and make some dyno runs.

Thanks,
David

 

What is the cost of the headers and will they work with a borla cat back exhaust?

Thanks

 

Hello Hemi2456,

PM Sent with pricing.

 

can you headers/y-pipe be added to the factory system?

I have an 05 ram hemi sport and like the sound / sleeper look.

and are the HP numbers claimed on the site based on individual pieces or as a replacement of the entire system?

 

05_FL_Ram - These headers are for the 5.7L Hemi Magnum / Charger / 300C.

We do have headers available for your ram if your interested.

We just got a new order of JBA headers in stock and ready to go for the Charger / Magnum / 300C

Thanks,
David
