The Toyota Supra has long been hailed as a legendary sports car, known for its powerful performance and sleek design. One crucial component that contributes to its outstanding performance is the exhaust manifold. The exhaust manifold is responsible for collecting exhaust gases from the engine’s cylinders and directing them into the exhaust system. Upgrading the stock exhaust manifold can significantly enhance the Supra’s power and responsiveness. In this article, we will delve into two popular choices for the Toyota Supra: the HKS exhaust manifold and the GReddy exhaust manifold. We will discuss their features, benefits, and help you make an informed decision on which one is the right fit for your Supra.

HKS Exhaust Manifold: A Powerhouse for Your Supra

HKS, a renowned Japanese aftermarket parts manufacturer, offers a high-quality exhaust manifold specifically designed for the Toyota Supra. Their exhaust manifold is constructed with precision and attention to detail, utilizing durable materials to withstand the rigors of high-performance driving. The HKS exhaust manifold features a tubular design, allowing for improved exhaust gas flow and reducing back pressure. This design leads to enhanced horsepower and torque throughout the RPM range, resulting in a more exhilarating driving experience.

Moreover, the HKS exhaust manifold incorporates a merge collector, a crucial feature that optimizes exhaust gas scavenging. By efficiently collecting and directing exhaust gases, the merge collector helps to eliminate turbulence and increase exhaust velocity. This contributes to faster turbo spooling and improved throttle response, making the HKS exhaust manifold an excellent choice for Supra owners craving instant power delivery.

Additionally, HKS offers various versions of their exhaust manifold, including ones with a single scroll or twin scroll design, catering to different turbo setups or personal preferences. This customization allows Supra enthusiasts to tailor the exhaust manifold to their specific needs and goals. Whether you’re aiming for maximum horsepower on the track or a responsive streetcar, HKS has an exhaust manifold to suit your desires.

GReddy Exhaust Manifold: Unleash the Potential of Your Supra

GReddy, a respected name in the automotive aftermarket industry, presents their own exhaust manifold option for the Toyota Supra. GReddy exhaust manifolds are renowned for their excellent craftsmanship and performance gains. Designed with the utmost care, their exhaust manifold provides an optimal balance between power and reliability. Constructed from high-grade stainless steel, the GReddy manifold ensures durability while efficiently dealing with high exhaust gas temperatures.

The GReddy exhaust manifold features a tubular design similar to the HKS, allowing for improved exhaust flow and reduced back pressure. This translates to increased horsepower and torque, giving your Supra the extra push it needs to conquer the road or track. Additionally, GReddy offers various bore sizes for their exhaust manifold, allowing for compatibility with different turbo setups and applications.

Furthermore, GReddy exhaust manifolds are meticulously engineered to provide ideal fitment, ensuring a hassle-free installation process. This means less time in the garage and more time on the road, enjoying the thrilling performance of your Toyota Supra.
