Upgrade your vehicle's performance with our selection of exhaust headers, essential components in the Exhaust & Emissions category. These aftermarket headers replace restrictive factory manifolds, delivering better exhaust scavenging, increased horsepower, and a throaty exhaust note that enthusiasts crave. Whether you're tuning a classic Chevy truck or a sporty Mazda RX-7, our 15+ products offer durable stainless steel constructions, heat wraps, adapters, and repair kits to match your build.
What Are Exhaust Headers and Why Upgrade?
Exhaust headers are tuned exhaust manifolds designed for optimal flow. Unlike stock cast-iron manifolds with uneven runners, performance headers feature equal-length primary tubes that merge into a collector, reducing backpressure and improving engine breathing. This leads to noticeable gains in mid-range torque and top-end power, making them a favorite for street cars, trucks, and off-road rigs.
As part of the broader Replacement Parts lineup, headers fit seamlessly into custom exhaust systems. They're ideal for hot rods, daily drivers seeking efficiency, or racers chasing every horsepower. Common applications include V8 engines like the Chevy 305/350 or rotary powerplants in imports.
Key Benefits of Performance Exhaust Headers
- Increased Power: Better scavenging extracts exhaust gases faster, boosting HP by 10-30% depending on the setup.
- Improved Sound: Aggressive tone without drone, perfect for muscle cars.
- Weight Savings: Stainless or titanium options shed pounds compared to OEM.
- Durability: Corrosion-resistant materials withstand heat cycles and road salt.
- Heat Management: Paired with wraps to protect nearby components.
What to Look for When Buying Exhaust Headers
Select headers based on your vehicle's make, model, and goals. Primary tube diameter (1-1/2" to 2") affects low-end torque vs. high-RPM power—thinner for street, larger for track. Collector size and flange design ensure leak-free seals. Materials matter: 304 stainless steel offers polish and strength, while ceramic coatings reduce underhood temps.
Fitment is crucial—check bolt patterns for your engine. For Chevy C/K trucks (88-95), options like the PG POWERGO MOTORSPORT 1-1/2" stainless headers provide a direct bolt-on for 5.0L/5.7L V8s. Mazda RX-7 owners appreciate TUNERBITS manifolds for seamless integration.
Supporting Accessories in This Category
Beyond headers, stock up on essentials like Livoccur 2.5" stainless adapters for custom fab, ARTR titanium heat wraps with ties for insulation, and SINGARO rubber hangers for vibration damping. Repair kits, such as Dorman's manifold hardware for Jeeps or Jxsaboorle's 3.0" exhaust flanges with gaskets, fix leaks quickly without full replacement.

Types of Exhaust Headers for Different Needs
Long-Tube Headers: Maximize flow for racing, but may require emissions deletes.
Shorty Headers: Compact for tight engine bays, emissions-legal in many states.
Tri-Y Design: Balances torque across RPMs, great for trucks.
Extensions like RINGSHARK's chrome fishtail add style to motorcycle headers, while Dynomax resonators quiet aggressive setups without choking flow.
Installation Tips and Maintenance
Professional install recommended due to tight clearances and gasket needs. Use anti-seize on bolts, new gaskets, and exhaust sealant. Wrap headers with Arespark or ARTR tape to cut radiant heat by 50%. Regular checks prevent cracks from flexing.
Frequently Asked Questions
What is the difference between exhaust headers and exhaust manifolds?
Manifolds are factory castings optimized for cost and emissions; headers are tubular aftermarket designs prioritizing performance flow and power.
Do exhaust headers increase horsepower?
Yes, typically 10-30 HP gains on naturally aspirated engines, more with tuning, cams, or forced induction.
Are stainless steel headers worth it?
Absolutely—superior corrosion resistance, lighter weight, and mirror polish outlast mild steel or cast iron.
Will installing headers void my warranty or affect inspections?
Check local laws; CARB-approved options exist for emissions compliance. They rarely void powertrain warranties if installed correctly.
How do I choose the right header size?
Match primary tube size to engine displacement and RPM range: 1-5/8" for most street V8s, larger for big blocks or high-revving mills.
