Should I put headers on my truck?
Headers are installed because they boost the rate of exhaust flow out of your engine compared to OEM stock exhaust manifolds, which are typically designed to take up as little space as possible.

Are headers better than manifolds?
Why are headers are a better choice than an exhaust manifold? As stated above, exhaust manifolds create back pressure, which lowers performance. Because each cylinder of the engine is given its own tube, however, headers eliminate this problem; thus, allowing the gases to exit without the creation of back pressure.
Are headers good for the engine?
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.
Do headers increase mpg?
Exhaust headers are lighter. It is proven that exhaust headers which are tuned for economy, can improve the gas mileage by a small margin. And this is around 2-3 mpg improvement on the highway or city. This isn’t significant compared to the performance they deliver.

How much HP gain with long tube headers?
A full exhaust with long tubes and mid-pipe without any tune will gain around ~20-30 rwhp on average.
Are open headers bad?
Open headers are aggressive and cool when applied on the right settings – think drag strips where you are running on track. Running open headers on the street will get you in trouble for sure.
