That means that if one fails, both need to be replaced regardless of the issue. The majority of exhaust manifolds are more akin to tubular exhaust headers with attached catalytic converters.

Performance exhaust manifolds are a great bolt-n-go part with very little maintenance needed, unlike headers that require re-tightening periodically. This boosts your low-end grunt for towing and increases mileage when you’re just cruising. Even worse, some factory manifolds are prone to cracking, putting even the toughest trucks out of commission.Ī performance exhaust manifold, like the aFe BladeRunner Exhaust Manifold, wakes up your street machine with high-flow ductile iron or 304 stainless steel castings. Horsepower and torque are sacrificed in the name of lower manufacturing costs and increased emissions, sapping acceleration from your ride. Purely utilitarian, these heavy chunks of cast-iron do their job adequately, but don’t exactly inspire performance. Exhaust Manifold BenefitsĮxhaust manifolds perform the same role in funneling spent exhaust gas from the engine. So, instead of a common manifold shared by all the cylinders, each cylinder gets its own exhaust pipe, and then they come together in a larger pipe called the collector. The exhaust header helps eliminate the manifold’s back pressure. Once the exhaust gases vacate the cylinder, they end up in the exhaust manifold and then flow into one pipe toward the catalytic converter. During this stroke, the gasoline in the cylinder burns and expands to generate power. Your vehicle’s engine produces all its power during the power stroke.

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. So what’s the difference between exhaust headers and an exhaust manifold? They essentially do the same job, the distinction comes down to how they are made. manifolds to explain just how they work to improve your ride’s performance. Before you rush off to a complete overhaul, though, it’s important to know just how these parts work in order to decide what will deliver the best results. When exploring the world of bolt-on modifications, you’ll see these three things thrown around a ton, but what exactly is the deal with them, and how do they interact with each other to give you more power? if you’re looking for the first things to do for performance improvements and power gains, there are some parts that deliver better results than others.

As you first dive into the world of car modification, you’re tossed into a massive word salad with all sorts of words, terms, and acronyms that you’re supposed to know, but no one really ever takes the time to explain them.
