Why do people put headers on trucks?
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 is the best headers for a 350 small block?
Not only that, it can actually rob your engine of power. Most of our techs agree that a street application 350 will benefit well from a header with 1 1/2” to 1 5/8” diameter primary tubes and 2 1/2 or 3 inch collectors.
What’s the difference between short and long tube headers?
For shorty headers, the port pipes actually merge into a single exhaust pipe in a much shorter distance. For long tube headers, the exhaust pipes are much longer and merge farther out. Longer port pipes result in lower exhaust back pressure. This means improved oxygen intake and a boost in horsepower.
Are Shorty or long headers better?
Shorty headers aren’t as loud as long tube headers, although they’ll definitely have better sound than your stock manifold. You can choose unequal length headers for better sound, but equal length is the way to go for consistent gains in performance.
Are shorty headers worth the money?
If you’re driving a turboboosted engine, you will absolutely want shorty headers, but they’re also great for a variety of other drivers. If you’re looking to increase the performance of a vehicle that’s primarily your daily driver or commuter, shorty headers are a good idea.
Do shorty headers increase mpg?
While more involved from an installation standpoint, headers in combination with a cat-back system will give you a measurable boost in power. In most cases, fuel mileage will remain the same or improve a bit.
Are headers worth the money?
The answer is yes, headers will boost performance – IF your vehicle is “prepared” for them.
Will a ProCharger increase mpg?
On some vehicles, depending upon usage, the addition of a ProCharger will actually increase fuel economy. If fuel mileage and big power are on your mind, you have to take a look at the car below.
Will a high flow cat increase mpg?
In addition to free flowing mufflers, high flow catalytic converters can be used to increase exhaust flow and gain better gas mileage. Gains of 1-2 MPG have been documented when switching to high flow exhaust systems. Replace your stock muffler with a high flowing performance exhaust.
What are the benefits of high flow cats?
A high flow catalytic converter allows exhaust gases to flow through at a higher rate, lessening the restriction.
Does removing cat increase HP?
Vehicles with a removed catalytic converter have experienced a significant increase of horsepower. This has been made possible because the catalytic converter creates a considerable source of back-pressure on the engine. Without the catalyst’s limiting effects, the engine can now operate and use its optimum horsepower.
How much HP gain from removing catalytic converter?
At best, you can gain additional 15 horsepower when removing the CAT. This depends on the engine size – bigger engines have the potential to gain more horsepower when backpressure is decreased. If you bring your car to a tune after removing CAT, you can even double the horsepower gain to 30 horsepower.
How much HP gain from Cat Delete?
As a stand alone item, the gain was 2 HP with cat completely removed. The high flow cat tested only had a 1/2 HP gain over the stock cat.
Is a high flow cat worth it?
Yes in the sense that they allow for the more efficient flow of exhaust gasses, removing restrictions that can impede performance. Vehicle owners who’ve significantly upgraded their engine power output (say, by adding a Stage 3 EST Power Pack) will notice more power by upgrading.
Will a high flow cat cause a check engine light?
Typically when installing a higher flowing catalytic converter you will gain some extra exhaust volume, usually around about 15-20% louder without any other changes to the exhaust. The other issue to deal with is going to be a check engine light and a P0420 engine code – Catalyst efficiency below threshold.
Do high flow cats require a tune?
No high flow cats do not require a tune. As you are well aware, they will be optimized with a tune.
Are 100 cell cats legal in Australia?
Up to you what you get, I’m pretty sure they haven’t started emissions testing over here yet, but yes, 100 cell are illegal. 200 cell are the highest flowing legal cat in Australia. You may as well not even have cats with a 100 cell.
