Exhaust Manifold

Restore your vehicle’s power and efficiency with a premium EVIL ENERGY exhaust manifold. Whether you are dealing with a cracked factory part or looking to overhaul your entire exhaust system, our precision-engineered exhaust manifold kits provide the durability and perfect fitment your engine needs.

Optimize Your Engine's Breath

The exhaust system manifold is the first component your engine's exhaust gases encounter. It is critical to channel hot gases away from the cylinder head and into the exhaust pipe. A failing manifold can lead to exhaust leaks, reduced fuel economy, and hazardous fumes entering the cabin.

Our collection features car exhaust manifold solutions designed to withstand extreme temperature cycles without warping or cracking.

Why Choose an EVIL ENERGY Exhaust Manifold?

When upgrading or repairing, you need parts that last. Here is why drivers and mechanics choose our exhaust manifold kits:

  • Complete Solutions: Most of our units are sold as a full exhaust manifold kit, including necessary gaskets, bolts, and heat shields (check specific product details) to ensure a hassle-free installation.
  • Durable Construction: Manufactured from high-grade cast iron or stainless steel to resist corrosion and thermal shock.
  • Precision Fitment: Engineered as a direct OE replacement, ensuring compatibility with your existing exhaust setup without the need for modification.
  • Leak Prevention: Precision-machined flanges ensure a tight seal against the engine block, eliminating the ticking noise associated with exhaust leaks.

Understanding the Exhaust System Manifold

What does an exhaust manifold do? A car exhaust manifold collects the exhaust gases from multiple cylinders into one pipe. It acts as a funnel, directing hazardous gases through the catalytic converter and out the tailpipe.

Symptoms of a bad exhaust manifold: If you are unsure if you need a replacement, look for these signs:

  1. Loud Engine Noise: A ticking or tapping sound coming from the engine bay, especially during a cold start.
  2. Exhaust Smells: Raw exhaust fumes inside the car cabin.
  3. Check Engine Light: Often triggered by oxygen sensor readings caused by an air leak in the manifold.
  4. Visible Cracks: Hairline fractures on the manifold surface.

Find the Right Fit for Your Vehicle

At EVIL ENERGY, we stock a wide variety of manifolds for different makes and models. Whether you drive a truck, SUV, or sedan, upgrading to an EVIL ENERGY exhaust manifold ensures you get reliable performance at a fraction of the dealer cost.

Pro Tip: When replacing your manifold, always check the condition of your engine mounts. Worn mounts can cause excessive engine vibration, which is a leading cause of manifold cracking.

FAQs About Exhaust Manifold

Got Questions About Your Exhaust Manifold? Many drivers don't realize the importance of this component until they hear a ticking noise or smell exhaust fumes. As the component that withstands the most extreme thermal stress in your vehicle, a healthy manifold is vital for both cabin safety and fuel economy. Below, we answer the most common questions about the EVIL ENERGY exhaust manifold to help you troubleshoot issues and make the right repair decision.

An exhaust manifold is the first section of a vehicle's exhaust system. It is usually made of cast iron or stainless steel and bolts directly to the engine cylinder head. Its primary job is to collect exhaust gases from multiple engine cylinders and funnel them into a single pipe that leads to the catalytic converter and muffler.

The exhaust system manifold performs three critical functions:
1. Collection: It gathers hot combustion gases from the engine's cylinders.
2. Scavenging: A well-designed manifold helps "pull" exhaust out of the cylinder, allowing the engine to breathe better and produce more power.
3. Heat Management: It absorbs intense heat and channels it downstream to heat up the catalytic converter quickly for emissions control.

An exhaust manifold operates under extreme thermal stress. Under normal driving conditions, temperatures typically range between 1,200°F and 1,500°F (650°C to 815°C). However, in high-performance or turbocharged applications, or when towing heavy loads, the manifold can glow red hot and exceed 1,800°F. This extreme heat is why factory manifolds often crack over time and require an exhaust manifold kit for replacement.

EVIL ENERGY Fuel Pressure Regulator 6AN EFI Bypass Return Adjustable 20-140psi Black&Red - Red

Durable Construction: Precision-machined 6061-T6 aluminum alloy, corrosion-resistant and heat-tolerant (withstands harsh engine bay conditions), ensuring long-term reliability.

EFI System Compatibility: Fits most vehicles' electronic fuel injection (EFI) systems; maintains stable fuel pressure for optimized combustion, performance, and fuel economy.

Fuel Compatibility: Works with gasoline, E85, and alcohol/ethanol; not compatible with diesel fuel; note: nylon braided fuel lines are not E85-compatible (use PTFE-lined hoses for E85).

Bypass Return Design: Prevents pressure spikes during acceleration, boost, or high-load scenarios, protecting fuel injectors and rails from damage.

All-in-One Kit: Each variant includes essential components (fuel pressure regulator, pressure gauge, fittings, sealant tape, tools like Allen keys); no extra purchases needed for standard installation.

Easy Installation & Tuning: Adjust pressure via top set screw (clockwise = increase, counterclockwise = decrease); use thread sealant tape on NPT gauge port to avoid leaks; professional installation highly recommended (especially for high-pressure variants).

FAQs about Exhaust Manifold

How to fix a cracked exhaust manifold?

There are generally two ways to address a cracked manifold:

  1. Replacement (Recommended): The most permanent fix is to remove the damaged part and install a new EVIL ENERGY exhaust manifold. This ensures structural integrity and a proper seal.
  2. Welding (Temporary): You can attempt to weld a crack, but because cast iron becomes brittle with heat cycling, the crack often returns or spreads near the weld.

The cost depends largely on whether you go to a dealer or do it yourself.

  • The Part: A premium aftermarket exhaust manifold kit from EVIL ENERGY is significantly more affordable than an OEM dealer part, often saving you hundreds of dollars.
  • The Labor: If you pay a mechanic, labor costs can be high because bolts often rust and break during removal. DIY installation of an EVIL ENERGY exhaust manifold is a great way to save money if you have the right tools.

In broader mechanical terms, a 'manifold' is any chamber that branches into several openings. The specific purpose of the exhaust manifold is to ensure the smooth, efficient flow of waste gases away from the engine. By preventing backpressure (resistance to flow), the manifold allows the engine to burn fuel efficiently, maintaining horsepower and fuel economy.

While many enthusiasts perform this repair, it can be labor-intensive. Rusty bolts are common; we recommend using penetrating oil and having the proper torque specifications ready.

Our manifolds are designed to match OE specifications, meaning they connect perfectly to your factory catalytic converter or downpipe.
