HJS German imported catalytic converters are made from some of the highest grade materials you can find in a catalytic converter. This yields high performance gains and longevity so it wont deteriorate over time like lower grade catalytic converters. These catalytic converters flow up to 93-95% of a straight pipe in most applications. The benefit is that you get the “straight pipe sound” while still being able to provide enough emissions scrubbing to prevent a check engine light. Code M3List saves on the entire AutoTalent website!

Supersprint sport cats for the E46 M3 are designed to work with their cat-less headers or to replace factory Euro cats. The Supersprint sport cats are much freer-flowing than a traditional stock cat. With less restriction, less effort is required to move the exhaust gasses which will free up horsepower and torque. This cat section will mount to the Supersprint headers (p/n 044901) and then to a section 2. This section is built with O2 sensor bungs pre-installed after the cat if you wanted to extend your stock post-cat O2 sensors (however, special software may still be needed). Note the direction of the front flanges – they have to match the orientation of your existing header flanges.
These new exhaust pipe from Supersprint offer up to 25% greater exhaust flow than the original pipes offered before that were designed for sport street and light track use. This is perfect for vehicles that are heavily modified, turbocharged, or supercharged and can greatly benefit from the increased exhaust flow. Designed for vehicles that are capable of producing an excess of 400 horsepower, these pipes will ensure smooth exhaust flow all throughout the power band.
Want more rasp and volume to come through from your exhaust? This Supersprint section 2 will replace and delete the factory resonator that sits before the muffler. Without the resonator there to dampen the sound the overall volume will increase and let more S54 rasp come through. Combine this with the Supersprint section 1 straight pipes for even more Motorsport rasp. This section 2 pipe will bolt up to a stock section 1 or cat section and any muffler. It’s perfect for getting just a little more volume from your stock exhaust without changing the muffler.
The Supersprint rear resonator for the E46 M3 is designed to help you tune your exhaust to your personal taste. If you’re not a fan of the stock raspy exhaust note of the M3 this Supersprint resonator can help to reduce it. Or if extensive exhaust modifications have made the exhaust too loud this resonator can help quiet and dampen the overall volume. This fits in section 2 of the exhaust – after the front resonator section 1 and before the rear muffler.

High horse power performance applications require the durability and free flow characteristics of metallic racing catalytic converters. Turning up the power or using you car on the track will quickly melt down and damage your O.E. ceramic catalytic converter. Each racing converter is manufactured to racing specifications utilizing a high heat resistant metallic core. The reduced cell count from the O.E. 400 C.P.S.I. to a high flow 200 C.P.S.I. makes the Supersprint racing converters the most free flowing on the market today.

The BMW E46 M3 is a legendary sports car that has left an indelible mark on automotive enthusiasts for its exceptional performance and unmistakable exhaust note. One of the secrets to its thrilling auditory experience and impressive power is its exhaust system, which includes key components such as exhaust sections and the X-pipe. In this article, we’ll explore these components and how they contribute to the E46 M3’s distinctive sound and performance.
The E46 M3’s exhaust system is designed with precision and performance in mind. It consists of various sections, each contributing to the car’s overall performance and acoustic signature. Let’s break down these exhaust sections:
Headers: The exhaust headers are responsible for collecting exhaust gases from the engine’s cylinders and directing them into the rest of the exhaust system. In the E46 M3, the headers are engineered for maximum efficiency and power production. They also contribute to the iconic inline-six engine’s signature raspiness.
Mid-Pipes: Following the headers, the exhaust gases flow into the mid-pipes. These pipes are crucial for maintaining exhaust flow and reducing backpressure. In a performance-oriented car like the E46 M3, they are designed to minimize restrictions and improve engine efficiency.
Catalytic Converters: To meet emissions regulations, the E46 M3 is equipped with catalytic converters, which help reduce harmful emissions. However, aftermarket performance headers and high-flow cats are popular upgrades for those seeking enhanced power without sacrificing too much on emissions compliance.
Resonators: Resonators are strategically placed in the exhaust system to eliminate or dampen specific frequencies of exhaust noise. They help shape the unique sound profile of the E46 M3’s inline-six engine.
Mufflers: The final component of the exhaust system, mufflers, plays a critical role in fine-tuning the car’s exhaust note. The E46 M3’s mufflers are designed to maintain a balance between sportiness and refinement.
The X-pipe is a distinctive feature in the E46 M3’s exhaust system and plays a pivotal role in creating its signature sound. This crossover section connects the left and right exhaust paths and is positioned after the headers and catalytic converters but before the mufflers. The X-pipe serves several essential functions:
Balance: By combining the exhaust gases from both sides of the engine, the X-pipe ensures a more balanced exhaust flow. This balance is key to the inline-six engine’s harmonious and aggressive sound.
Enhanced Performance: The X-pipe design reduces exhaust backpressure, allowing the engine to breathe more freely. This improvement in exhaust flow can lead to enhanced horsepower and torque, making it a performance-enhancing component.
Sound Tuning: The X-pipe’s specific design influences the exhaust note. It is responsible for the melodious, raspy sound that is a hallmark of the E46 M3. Enthusiasts often opt for aftermarket X-pipes to fine-tune the exhaust note to their liking.
Many E46 M3 owners choose to further customize their exhaust systems with aftermarket components. Performance headers, high-flow catalytic converters, and X-pipe upgrades are common choices to unlock even more power and to fine-tune the sound. Aftermarket exhaust options offer a broader range of sonic possibilities, from a deep and aggressive growl to a high-pitched, racing-inspired tone.
The BMW E46 M3’s exhaust system, with its various sections and the distinctive X-pipe, is not just a mechanical necessity; it’s an essential element of the car’s personality. The harmonious blend of performance and sound makes the E46 M3 an enduring favorite among automotive enthusiasts. Whether you’re chasing enhanced performance or seeking to perfect the E46 M3’s signature exhaust note, understanding these components is key to unleashing the full potential of this iconic sports car.
