BMW Performance Headers & Downpipes for BMW 3 Series E46 (1999-2005)

Clear BMW chassis

Please ensure your correct model is selected

Headers are a bolt-on component that will make a huge improvement in how your BMW performs. As a replacement for your factory BMW exhaust manifold, our BMW headers provide a more direct path for exhaust gasses leaving your engine. Headers prevent your BMW's exhaust pulses from 'fighting' one another as they leave the head. The end result is that BMW headers give you more power and torque, and you'll love the high-winding top end push that a free-breathing engine exhibits. BMW headers are a must-have if you're doing any engine modifications on your vehicle. Along with a cold air intake, BMW headers provide the free-flowing exhaust necessary to get the most power out of your motor.

The Supersprint headers are among the best on the market for making the most top-end power on the M50/S50US engines. These are a long-tube equal length design which maximizes airflow for excellent power gains. On their own these can be good for 12-15hp (and more with other modifications). These are the real deal stainless steel headers with beautiful construction and design (often copied for cheap auction sites but made from mild steel).

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust design because every aspect is done to such a high level. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

Experience the latest design innovation from Supersprint for the E46 M3 -- 'stepped' design headers. While the technology has been in widespread use in Formula 1 for awhile, this is the first application of a stepped design on the E46 M3. In an engine that is tuned as much as the S54, airflow management is critical in getting big horsepower numbers from the exhaust. The Supersprint design is the next step in innovation in header design. By slightly increasing the size of the pipe diameters as the exhaust system moves away from the engine, the exhaust can flow more air. Supersprint design is tuned specifically for the S54 engine which is important in making more power without losing low-end torque. The headers merge into a precision-fit merge collector. Total horsepower gain with the complete system over a US Vehicle would be more than 30 hp. 15-19 hp gain over 'Euro-style' headers full stepped tubular and equal length headers bolts to the engine with factory hardware and gaskets used with Supersprint stepped section 1 (with or without cats) Included in this kit are Supersprint metallic sport cats designed to pair right up top Supersprint's own stepped headers. The piping is slightly oversized and 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 only mount to the Supersprint full stepped headers (p/n 044001) and then to any section 2. These cats are 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). When deciding on the right exhaust the hardest part is feeling confident in the best sound mixed with increased performance, this really leaves you to guess based on reputation. Fortunately, Supersprint has the reputation covered when it comes to BMW exhausts. For over 60 years their goal has always been designing and building the highest quality exhaust available. This has been achieved through extensive testing using real race teams to get the best feedback there is to offer, from the ones who demand the best every day. Extensive dyno testing, high-quality materials, and race team feedback are what allow Supersprint to extract the power from your engine, not just the noise. Supersprint exhausts offer quality, performance, and a great reputation that no other systems on the market can match!

Special Pricing! These Supersprint 'partial-stepped' headers for the Euro E46 M3, MZ3, and Z4 M are a replacement for the stock manifolds/cats. These are the tubular 'stepped' equal length headers (not the full racing stepped headers) - the header pipes increase in diameter the further they get from the engine until terminiating in a stock Euro-type flange. These stepped headers will bolt to the stock section 1 of the Euro exhaust. For making E46 M3 horsepower and performance gains, headers are right at the top of the list (along with changing the rear end gears). Since the stock catalytic converters are in the original exhaust manifolds, using any type of tubular non-cat manifolds will give instant power gains. The Supersprint headers are full 304 stainless steel (not mild steel) for better heat dissipation and heat resistance to cracking and de-forming (any headers not made from stainless suffer from structural problems). Supersprint designs their headers with CAD programs and 50 years of exhaust tuning experience. These headers are an improvement over any 'Euro style' header on the market. This part is designed for the Euro market with the correct flanges for the Euro exhaust and the O2 and EGT sensor ports pre-installed. Special software or stand alone engine management would be required to keep check engine and fault codes from appearing. Software is recommended to maximize the performance gains from this header upgrade.

Supersprint exhaust is widely recognized as the leader in complete exhaust system upgrades - extremely high quality, well designed for optimal flow, and amazing sound. Even at a premium price Supersprint is an unbeatable exhaust design because every aspect is done to such a high level. Most Supersprint systems are built with larger diameter piping to improve exhaust flow which helps the engine do less work and make more horsepower! Supersprint exhausts generally run at a premium over other systems but no other system on the market can match their quality, performance, or reputation!

The catalytic converter is an emissions device that converts the exhaust gasses exiting the engine into a less toxic substance. This is achieved through the internal honeycomb monolith, washcoat, and the catalyst itself that commonly consists of a mix of precious metals. Unfortunately the catalytic converters do not last forever, and can be damaged if the engine is running too rich on fuel. If you're getting an oxygen sensor fault, and the sensor is ok, the likely cause is a failed catalytic converter. Relieve worry about an upcoming emissions test and replace your faulty or damaged catalytic converter.

The catalytic converter is a crucial emissions control device designed to transform exhaust gases from your BMW engine into less harmful substances. Featuring an internal honeycomb monolith, washcoat, and a catalyst made from precious metals, this component effectively reduces toxic emissions. Over time, catalytic converters can degrade, especially if the engine runs rich on fuel. A malfunctioning catalytic converter may trigger an oxygen sensor fault, even if the sensor itself is functional.

To ensure your BMW passes emissions tests and maintains optimal performance, consider replacing a damaged or faulty catalytic converter.

  • Durable Stainless Steel Construction: Ensures long-lasting performance and resistance to harsh conditions.
  • Federal Emissions Compliant: Meets regulatory standards for reduced environmental impact.
  • Versatile Application: Suitable for both gas and diesel engines, providing a broad range of compatibility.

Replace your faulty or damaged catalytic converter with this high-quality unit designed for BMW vehicles. The catalytic converter plays a crucial role in reducing exhaust emissions by converting harmful gases into less toxic substances. It utilizes an internal honeycomb monolith, washcoat, and a catalyst composed of precious metals to achieve this. However, catalytic converters can degrade over time or get damaged if the engine runs too rich on fuel. If you encounter an oxygen sensor fault and the sensor itself is functional, a failed catalytic converter might be the issue.

  • Stainless Steel Construction: Ensures durability and resistance to corrosion.
  • Federal Emissions Compliant: Meets stringent emissions regulations for peace of mind.
  • Versatile Application: Suitable for both gas and diesel engines.

Ensure your BMW passes emissions tests with ease by upgrading to this reliable catalytic converter.
