The 13B-REW engine, a renowned rotary powerhouse, has captured the hearts of automotive enthusiasts for decades. Known for its lightweight design and high-revving capabilities, it’s no surprise that many owners seek ways to enhance its performance. One of the most effective modifications is the installation of an aftermarket exhaust system. This article explores how aftermarket exhausts can elevate the 13B-REW’s horsepower from 280 to 330 HP in under three hours.
Understanding the 13B-REW Engine
The 13B-REW is a part of Mazda’s Wankel rotary engine family, featuring a unique design that sets it apart from traditional piston engines. Its compact size and lightweight nature contribute to the vehicle’s agility and performance. However, to unlock its full potential, modifications are often necessary.
Benefits of Aftermarket Exhaust Systems
Upgrading to an aftermarket exhaust system offers several advantages:
- Increased Flow: Aftermarket exhausts are designed to reduce back pressure, allowing for better exhaust flow.
- Weight Reduction: Many aftermarket systems are lighter than factory options, improving overall vehicle performance.
- Improved Sound: A new exhaust can enhance the engine’s sound, providing a more aggressive tone.
- Enhanced Aesthetics: Custom exhausts can improve the visual appeal of the vehicle.
Choosing the Right Aftermarket Exhaust
When selecting an aftermarket exhaust for the 13B-REW, consider the following factors:
- Material: Stainless steel is a popular choice due to its durability and resistance to corrosion.
- Type: Cat-back systems are common for performance upgrades, as they replace the exhaust after the catalytic converter.
- Design: Look for designs that optimize flow, such as straight-through or mandrel-bent pipes.
- Brand Reputation: Choose reputable brands known for quality and performance.
Installation Process
Installing an aftermarket exhaust on a 13B-REW can typically be completed in under three hours with the right tools and preparation. Here’s a step-by-step guide:
- Gather Tools: You will need a jack, jack stands, socket set, and possibly a saw for cutting.
- Lift the Vehicle: Safely raise the vehicle using a jack and secure it with jack stands.
- Remove the Old Exhaust: Disconnect the existing exhaust system, starting from the rear and working towards the front.
- Install the New Exhaust: Position the new exhaust system and secure it in place, ensuring all connections are tight.
- Check for Leaks: Start the engine and inspect for any exhaust leaks, making adjustments as necessary.
Expected Power Gains
With the installation of a high-quality aftermarket exhaust, owners can expect significant power gains. The transition from 280 to 330 HP is achievable due to:
- Improved Exhaust Flow: Enhanced flow reduces engine strain and improves combustion efficiency.
- Optimized Tuning: Many aftermarket systems are designed to work in conjunction with ECU tuning for maximum performance.
- Complementary Modifications: Pairing the exhaust with other upgrades, such as intake systems, can further enhance power output.
Conclusion
Upgrading the exhaust system on a 13B-REW engine is one of the most effective ways to boost horsepower. Achieving a jump from 280 to 330 HP can be accomplished in a matter of hours, making it a popular choice among enthusiasts looking to enhance their vehicle’s performance. With the right aftermarket exhaust, the 13B-REW can truly shine, delivering an exhilarating driving experience.
