Experience the full potential of your turbocharged BMW with the Evolution Racewerks Competition Series 4" Catted Downpipe for the B46 engine. Turbocharged cars are often limited by exhaust flow restrictions, which result in reduced horsepower and torque. The culprit is the factory catalytic converter, designed with tiny "honeycomb" weaves that impede exhaust gas flow, causing turbulence and slowing down the exhaust flow. Our Competition Series 4" catted Downpipe is engineered to remove these restrictions, unleashing more power and performance.
Key Features:

Through extensive dyno testing, we have observed remarkable average peak gains of 14-16whp and up to 24wtq. However, what truly matters is the power curve. Our downpipe delivers torque earlier and with greater intensity, creating a broader torque curve throughout the RPM band. This translates to more usable power, with higher horsepower and torque sustained for longer periods. Experience faster turbo spool up, reduced turbocharger lag, and improved throttle response. The difference in performance is instantly noticeable and exhilarating.
In addition to performance gains, we prioritize the durability and longevity of our products. Unlike many competitors, we understand the importance of a flex bellow section in the exhaust system. Our downpipe incorporates a 100% stainless steel flex section, reducing stress on the exhaust components, including the exhaust system, downpipe, turbocharger, and exhaust manifold. This design minimizes wear and tear, preventing premature cracks and failures that can occur without proper flexibility. It also allows the exhaust system to deflect impact, ensuring optimal performance and protection, even on lowered cars.
Another standout feature of our B46/B48 downpipe is the CNC machined solid stainless steel billet ball joint. Unlike the press formed "ball" joint used in factory downpipes, our CNC machined ball joint eliminates turbulence and maintains high exhaust flow velocities. By reducing backpressure and optimizing flow, turbocharger lag is further reduced, resulting in faster spool times and improved throttle response. The interior of our ball joint is meticulously designed for unrestricted exhaust flow, promoting optimal performance.
To ensure perfect fitment and compatibility, our downpipes are designed to replicate the factory "ball" joint v-band connector. This guarantees a seamless installation with either the factory exhaust system or aftermarket exhaust systems. There are no compatibility issues whatsoever, allowing you to enjoy the benefits of our downpipe without any hassle. By default, the downpipes come with a brushed finish, combining performance and aesthetics.
For those seeking additional enhancements, we offer optional features. Our ceramic thermal coating is designed to keep heat trapped within the downpipe, reducing underhood temperatures and minimizing heat absorption by surrounding parts and surfaces. This not only improves performance by maintaining high exhaust flow velocities but also provides added corrosion resistance. The ceramic coating can withstand temperatures up to 2000F and is available in black, ensuring durability and visual appeal.
To enable advanced monitoring of air/fuel ratios, we provide an option to add an additional O2 sensor bung. This allows for easy installation of wideband O2 sensors and gauges, ensuring precise tuning and optimization of engine performance. Similarly, the optional EGT (Exhaust Gas Temperature) bung enables the integration of an EGT sensor and gauge, providing valuable insights into exhaust gas temperature levels. Both the additional O2 sensor bung and optional EGT bung come pre-installed with plugs for convenience.
As a token of appreciation, we include a free Evolution Racewerks keychain lanyard and license plate frame with your purchase. At Evolution Racewerks, we prioritize performance without compromises, providing you with a high-quality, meticulously engineered downpipe that unlocks the true potential of your BMW. Upgrade your vehicle today and enjoy the exhilaration of increased power, improved throttle response, and enhanced turbocharger performance.
