Automotive enthusiasts looking for more power and torque often turn to Flowmaster headers as one of the best bolt-on upgrades for their vehicle. But what exactly are Flowmaster headers, and why are they so popular? In this blog, we’ll take an in-depth look at everything you need to know about these high-performance exhaust headers.
What Are Flowmaster Headers?
Flowmaster headers are specially designed exhaust manifolds or headers that optimize exhaust flow and improve performance. Manufactured by Flowmaster, a leading brand in performance exhaust systems, these headers help engines breathe better and exhaust gases escape more smoothly.
The carefully tuned tubes and collectors in Flowmaster headers allow exhaust gases to flow faster and more freely compared to restrictive stock manifolds. This reduces backpressure which helps unleash more horsepower and torque from the engine. The headers are usually made from stainless steel or ceramic-coated metals for durability and corrosion resistance.
How Do Flowmaster Headers Improve Performance?
There are several ways Flowmaster headers can enhance your vehicle’s performance:
- Increased Horsepower and Torque – By improving exhaust flow, Flowmaster headers help the engine optimize its breathing and combustion efficiency. This directly translates to better horsepower and torque output compared to restrictive stock manifolds. Expect gains of 10-25 HP depending on the vehicle.
- Faster Spool Up – The smooth exhaust flow enables the engine and turbocharger to spool up faster. This improves throttle response which is crucial for acceleration and passing power.
- Weight Savings – Flowmaster headers are often lighter than heavy stock cast iron manifolds. Less weight improves handling and fuel economy.
- Looks and Sound – The distinct header tubes and bold Flowmaster logo give your engine bay a racy look. And they deliver a deeper, more aggressive exhaust tone.
What Types of Vehicles Are Compatible?
Flowmaster produces headers for a wide variety of domestic and import cars, trucks, SUVs, and muscle cars. Some popular applications include:
- Ford Mustang, F-150, Crown Victoria
- Chevy Camaro, Corvette, Silverado
- Dodge Ram, Charger, Challenger
- Jeep Wrangler, Cherokee, Grand Cherokee
- Toyota Tacoma, Tundra, 4Runner
- Nissan 350Z, Titan, Frontier
- BMW 3-Series, 5-Series, 7-Series
- Scion tC, FR-S
So whether you drive a classic muscle car or a modern import, Flowmaster likely has a set of headers specifically tuned for your ride. Custom fabrication services are also available.
Performance Headers for Trucks and SUVs
For truck and SUV owners seeking more power, Flowmaster headers provide significant gains for pickups, Jeeps, and 4x4s. Choose from:
- Long-tube headers for maximum flow and horsepower
- Shorty headers for torque and clearance when off-roading
- Clearance-fit headers to fit oversized tires and lifts
- High-flow Y-pipe connectors to replace restrictive factory pieces
With stainless steel construction, Flowmaster truck headers stand up to towing, hauling, and extreme use while delivering more torque when you need it.
Durable Construction and Materials
Flowmaster uses premium materials and precise fabrication for exceptional fitment and durability. Features include:
- Stainless Steel – 304 and 409 grades resist corrosion and withstand high temps.
- Ceramic Coating – Silver ceramic coating provides insulation and extra protection.
- Precision Welds – Robotic and hand TIG welding ensures leak-free construction.
- Mandrel Bends – Mandrel bent tubes have smooth interiors that maintain flow.
- Oversized Ports – High-flow collectors and merge collectors boost velocity.
- Gaskets and Hardware – OEM-grade gaskets and bolts are included for a secure seal.
Aggressive Sound, Smoother Flow
One of the most noticeable benefits of Flowmaster headers is the aggressive exhaust sound they produce. As gases pass through the specially tuned tubes, they create a deep authoritative tone that enhances the thrill of driving.
At the same time, the interior design features like merge collectors help smoothen the exhaust pulse. This reduces resonance and drone at cruising speeds, giving you the best of both worlds – a race car sound when accelerating yet pleasant highway manners.
Key Benefits of Flowmaster Headers
Here are some of the most notable benefits of upgrading your vehicle with a set of Flowmaster headers:
- Horsepower Increase – Expect 10-30% more HP for bolt-on performance.
- Torque Improvement – More low-end torque improves acceleration and towing capacity.
- Faster Turbo Spool Up – Optimized exhaust flow reduces turbo lag.
- Weight Reduction – Lighter than stock manifolds; reduces vehicle weight.
- Exhaust Sound – Aggressive tone enhances driving excitement.
- High Quality – Durable TIG welded stainless steel construction.
- Custom Options – Headers can be customized for racing applications.
How Flowmaster Headers Compare to Other Brands
When researching exhaust headers, you’ll find brands like BBK, OBX, Pacesetter, and others. But Flowmaster headers stand apart for their combination of quality, performance, sound, and reliability.
They are not the cheapest headers available. However, their use of thick stainless steel, smooth mandrel bends, and extensive R&D results in headers that outperform cheaper options. Flowmaster headers also come with a limited lifetime warranty for peace of mind.
For vehicle owners who want maximum horsepower, the long tube Dynatech Max-Flow headers represent Flowmaster’s premium racing line. They provide professional grade performance at a reasonable cost.
Improving Fuel Efficiency
In addition to increasing power, Flowmaster headers can also help improve fuel efficiency in some applications. When an engine breathes more efficiently, it can burn fuel more optimally in the combustion cycle.
Owners of modified turbocharged vehicles often report 1-2 MPG fuel economy gains after installing headers. Even naturally aspirated engines may benefit slightly from the exhaust flow improvements. Every bit of fuel savings counts when gas prices are high!
How Are Flowmaster Headers Installed?
Typical installation steps for Flowmaster headers include:
- Removal of stock exhaust manifold – Disconnect and remove factory exhaust manifold and gaskets. This may require cutting exhaust pipes.
- Header test fitting – Test fit the new headers and check for tight clearances. Some minor adjustments may be needed.
- Install header gaskets – Use new gaskets between header tubes and cylinder head ports.
- Bolt on headers – Attach the headers using supplied hardware and a torque wrench.
- Fabricate exhaust pipes – Extend the header collectors with new exhaust pipes and hangers. Consider using Flowmaster reducers and a cat-back system.
- Check for leaks – Start the engine and check for any exhaust leaks at gasket surfaces. Retorque if needed.
The entire process takes 3-6 hours for DIYers to complete, or can be installed professionally in 1-2 hours. No engine tuning is required, though a tune helps maximize gains.
