How much horsepower does long tube headers add to a 5.7 Hemi?
The long-tube headers improved the peak power output from 407 horsepower to 434 horsepower, and the peak torque jumped up too, from 418 lb-ft to 439 lb-ft.Are long tube headers worth it?

What do long tube headers do?

Are headers good for your car?
Headers are one of the easiest bolt-on accessories you can use to improve an engine’s performance. The goal of headers is to make it easier for the engine to push exhaust gases out of the cylinders. … During the exhaust stroke, a good way for an engine to lose power is through back pressure.
What's the difference between headers and exhaust manifold?
The difference between them is that an exhaust manifold is a solid cast iron structure across all cylinders while an exhaust header is made up of a series of individual steel tubes for each exhaust port, welded to meet at a collector to bring the exhaust gases down to a single pipe.
Do you need a tune for headers?
