BMW Performance Headers & Downpipes

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 factory cast-iron exhaust manifolds originally fitted to M50, M50TU, and S50B30US-powered E36s are notorious performance bottlenecks, plagued by excessive weight and a tendency to crack over time. Our Equal Length "Shorty" Exhaust Headers offer the ultimate remedy. Engineered specifically to maximize exhaust flow and encourage exhaust gas scavenging, these headers unleash a noticeable boost in overall engine efficiency and grant your M5X that crisp, aggressive inline-six growl without sacrificing low-end torque.

Unlike restrictive, uneven OEM cast-iron manifolds, our design utilizes high-quality T304 stainless steel construction shaped by precision mandrel bending. This specialized process ensures a uniform pipe diameter throughout every bend to maximize exhaust gas velocity and eliminate internal turbulence. The flow-optimized, equal-length primary runners merge seamlessly into a heavy-duty cast stainless steel collector, creating a restriction-free transition that dramatically improves scavenging. Our refined design completely transforms your driving experience, delivering a deeper, more pronounced tone under load while remaining perfectly civilized and drone-free at cruising speeds.

Built to endure years of high-RPM track abuse and extreme thermal stress, these headers are engineered with longevity in mind. Every joint is meticulously TIG-welded for exceptional structural integrity, ensuring the tubes can handle intense heat cycling without cracking. To guarantee a permanent, leak-free seal, the headers feature thick, precision laser-cut flanges that aggressively resist warping over time. Best of all, this is a true, headache-free upgrade; they drop directly into the E36 chassis and mate perfectly with your factory mid-pipe using OEM gaskets and hardware, requiring absolutely no custom fabrication or modification.

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.

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.

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.
