If you are building a Honda B-Series engine, you already know it’s one of the most responsive platforms ever made. But if you’re still running the factory exhaust manifold, you are essentially choking your engine’s potential.
Upgrading your exhaust headers is often the single most effective bolt-on modification you can make to unlock the high-RPM scream these engines are famous for.
In this guide, we are cutting through the forum noise to compare the best headers on the market. We will analyze the dyno data and help you decide which setup is right for your build.
Top 5 B-Series Headers from Private Label Mfg
If you're serious about unlocking your B-Series engine's potential, choosing the right header is critical. Private Label Mfg offers five distinct header designs, each engineered for specific power goals and driving styles.

2. PLM Power Driven TA Header
The PLM Power Driven B-Series TA Header is the best-selling B-Series header on the market, trusted by enthusiasts and professionals worldwide. Featuring a true 4-2-1 Tri-Y merge collector inspired by the iconic Toda Racing design, this header delivers optimal low to mid-range torque with significant peak horsepower gains. The short-tube design ensures more equal exhaust flow for a broad, usable powerband. Recommended for 1.6L to 2.0L engine displacements.
Constructed as a one-piece unit from 18-gauge 304 stainless steel with CNC-machined manifold flanges (.38" thick) and a true 2.5" OD collector. The one-piece design offers superior durability and ease of installation compared to multi-piece alternatives. Backed by a one-year warranty.
3. PLM Tri-Y Big Tube Header
The PLM B-Series Tri-Y Big Tube Header has been a best-seller for over 15 years, delivering proven big tube power for B18 and B20 engines. Featuring a true stepped exhaust design with long-tube construction, this header maximizes low to mid-range power gains through optimized exhaust velocity and flow.
The two-piece slip-fit design ensures seamless fitment for maximum horsepower output. Recommended for B18 and B20 engine displacements where big tube equals big power.
Constructed from 16-18 gauge stainless steel with professionally hand TIG-welded Tri-Y collectors and 3/8" thick flanges. Compatible with 92-00 Honda Civic (EG/EK) and 94-01 Acura Integra (DC2) with B-Series swaps. Not compatible with A/C in the stock factory location, but can work with slim fans and A/C line re-routing. Backed by a one-year warranty.
4. PLM Power Driven TA Header
The PLM Power Driven B-Series B20 TA Header for CR-V RD1 AWD is the most popular bolt-on fitment solution for first-generation all-wheel-drive CR-Vs.
Featuring the same proven 4-2-1 Tri-Y merge collector design as the best-selling standard TA Header, this AWD-specific version delivers optimal low to mid-range horsepower plus peak horsepower gains through more equal exhaust flow. The one-piece design is engineered specifically to fit AWD models with direct bolt-on compatibility to the OEM catalytic converter.
Constructed from 18-gauge 304 stainless steel with beautiful 100% TIG welds, CNC-machined manifold flanges (.38" thick), and a true 2.5" OD short-tube Tri-Y merge collector. Engineered and designed in the USA. Includes both gaskets and hardware for complete installation. Backed by a one-year warranty.
5. PLM Power Driven B-Series Swap TA AWD Header
The PLM Power Driven B-Series Swap TA AWD Header is the most popular solution for AWD all-wheel-drive B-Series swaps in EG Civic, EK Civic, and DC2 Integra chassis.
Featuring the proven 4-2-1 Tri-Y merge collector design, this AWD swap-specific header delivers optimal low to mid-range horsepower plus peak horsepower gains through more equal exhaust flow. The one-piece design is engineered specifically for AWD swap applications, solving the fitment challenges that come with AWD drivetrain conversions.
Constructed from 18-gauge 304 stainless steel with beautiful 100% TIG welds, CNC-machined manifold flanges (.38" thick), and a true 2.5" OD short-tube Tri-Y merge collector. Engineered and designed in the USA. Requires extension pipe (sold separately). Includes both gaskets and hardware for installation. Backed by a one-year warranty.

B-Series Header Buying Guide
Choosing the right header comes down to understanding your build goals and how you actually drive your car. Here's what to consider before making your purchase.
Match the Design to Your Power Goals
4-1 headers deliver maximum horsepower above 6,500 RPM, ideal for drag racing and high-RPM track builds. 4-2-1 Tri-Y headers focus on mid-range torque between 3,500 and 6,500 RPM, better suited for street driving and autocross, where usable power matters most.
Verify Fitment for Your Application
Not all B-Series headers fit all chassis. Understanding the differences between FWD vs. AWD is critical, as each drivetrain has unique clearance requirements for headers. If you're running an AWD setup or doing an engine swap, confirm the header is designed for your specific drivetrain configuration.
Prioritize Quality Materials
304 stainless steel is the gold standard for header construction. It resists corrosion, handles extreme heat cycles, and maintains structural integrity far longer than mild steel alternatives. All Private Label Mfg headers use 304 stainless steel with precision TIG welding.
Plan Your Complete Exhaust System
A header delivers its best results when paired with supporting modifications. Combine it with an aftermarket catalytic converter (or test pipe where legal), a properly sized exhaust system, and an ECU tune to optimize air-fuel ratios.
Understand Legal Requirements
Most performance headers are designed for off-road and competition use only. They may not be legal for street use in California or states following CARB regulations. Check your local laws before installation.
Final Thoughts
Upgrading to a performance header is one of the most effective modifications you can make to your B-Series engine. Whether you need top-end power or mid-range torque, Private Label Mfg offers proven designs built from quality 304 stainless steel to match your specific build goals.
Choose the header that fits your driving style and unlock your engine's full potential.
