Exhaust Header VS Manifold, which is the better choice?
The key structural differences between exhaust headers and manifolds lie in their materials and design. Headers, like FLASHARK’s B18 headers, are made from lightweight stainless steel and feature a longer, individual tube design for each cylinder. In contrast, traditional cast iron manifolds are heavier and create more back pressure, which reduces performance. With headers, exhaust gases exit more efficiently, eliminating back pressure and boosting horsepower and torque.
Upgrading to a performance B18 exhaust header is essential for enhancing engine output and sound. Whether for track or street use, FLASHARK’s Tri-Y design offers a direct bolt-on solution with no modifications required—delivering better airflow, increased power, and a deeper exhaust tone.

Q1: Will these Acura Integra headers fit my specific B18 engine model?
A1: Yes, these headers are designed for high compatibility across the B-series platform. They fit the Acura Integra LS/GS (B18A1/B18B1) and the GSR (B18C1). Whether you have a non-VTEC or VTEC setup, our exhaust header for Acura Integra ensures a precise fit for 1994-2001 models.
Q2: What performance gains can I expect from installing these B18 headers?
A2: By replacing the restrictive factory Acura Integra exhaust manifold with our high-flow stainless steel B18 headers, you can expect an increase of 10-15 horsepower and improved mid-range torque. The mandrel-bent tubing reduces backpressure, allowing your engine to breathe more efficiently.
Q3: Are these headers a direct bolt-on for the Integra GSR?
A3: Specifically for the Integra GSR headers application, please note that the GSR factory exhaust is slightly shorter than the LS/GS models. Our headers are designed to be as versatile as possible, but for a perfect GSR fit, some minor adjustments to the catalytic converter piping might be required depending on your specific year.
Q4: What material is used for the Flashark exhaust header for Acura Integra?
A4: We use premium T304 Stainless Steel for all our Acura Integra headers. This material is chosen for its excellent heat resistance and durability against corrosion, ensuring your performance headers look and perform great for years, even under high-stress driving conditions.
Q5: Do these LS Integra headers include all necessary installation hardware?
A5: Absolutely. Each set of LS Integra headers comes complete with a high-quality manifold gasket and the necessary collector hardware. We aim to provide a "ready-to-install" solution so you can spend less time in the garage and more time on the road.
Q6: Will these B18B1 headers fit my 1990-1993 DA Integra?
A6: These specific headers are optimized for the 1994-2001 (DC2/DB8) chassis. While the B18B1 headers will bolt onto the engine block of a DA Integra, you may encounter clearance issues with the crossmember or require custom exhaust work to connect to the rest of the system.
Q7: What is the benefit of the 4-2-1 design used in these performance headers?
A7: Our Acura Integra exhaust manifold features a 4-2-1 tri-y design. This layout is superior for street-driven cars as it maximizes torque in the low-to-mid RPM range, which is where B18 engines spend most of their time, providing better "butt-dynamic" acceleration compared to a 4-1 race header.
Q8: Do these B18C1 headers require an aftermarket catalytic converter?
A8: These B18C1 headers are designed to meet the factory collector location for most setups. However, because B-series swaps and different trim levels vary in length, we recommend checking your catalytic converter's flange orientation to ensure a seamless connection.
Q9: Will I get a Check Engine Light (CEL) after installing these headers?
A9: No, our headers include pre-welded O2 sensor bungs in the correct locations to maintain proper sensor readings. As long as your oxygen sensors are in good working condition, you should not experience any CEL issues after installing these B18 headers.
Q10: Can I use these headers on a B20 swapped Integra?
A10: Yes! Since the B20 block shares the same exhaust port pattern as the B18 series, these headers are a popular choice for B20 swapped Integras. They provide the necessary flow to support the increased displacement of the 2.0L bottom end.
Q11: How do these headers affect the exhaust sound of my Integra?
A11: Installing these performance headers will give your Acura Integra a deeper, more resonant exhaust note. It eliminates the "tinny" sound of the stock cast manifold and provides a much cleaner, more aggressive tone when the VTEC kicks in.
Q12: Do I need to use heat wrap on these stainless steel headers?
A12: While T304 stainless steel handles heat very well, many enthusiasts choose to use heat wrap to further reduce engine bay temperatures and protect nearby components. However, it is not strictly necessary for the structural integrity of the Flashark headers.
