Description
Introducing the Evolution Racewerks Sports Series 4" High Flow Metallic Catted Downpipe, designed specifically for the BMW B48 four-cylinder turbo engine. This premium performance downpipe is engineered to enhance your BMW's performance by improving exhaust flow, reducing turbocharger lag, and increasing both horsepower and torque. Built for BMW models 230i, 330i, 430i, and 530i from 2016 and onwards, it’s crucial to note that this downpipe is for B48 engines found in European and Asian spec vehicles and is not interchangeable with the B46 engine found in U.S. spec models.
Built with a 200-cell metallic catalytic converter, this downpipe significantly reduces exhaust restrictions compared to the stock 900-cell ceramic converter, delivering more power and faster turbo spool. Constructed from 100% 304 stainless steel and TIG welded for precision, it also features a CNC-machined turbocharger V-band flange, stainless steel flex section for durability, and mandrel-bent piping for smooth exhaust flow. This downpipe is track-tested and built to withstand the rigors of high-performance driving.
Key Features:
- Designed for 2016+ BMW 230i / 330i / 430i / 530i with B48 engine.
- High-flow 200-cell metallic catalytic converter.
- Horsepower gains of 9-11 WHP, torque gains of 15-20 WTQ (with tuning).
- Improved throttle response and faster turbo spool times.
- 100% 304 stainless steel construction with TIG welds.
- Mandrel-bent 4" piping with smooth transitions for optimized flow.
- Mirror polished or brushed finish options.
- Optional high-temperature black thermal coating to reduce underhood temps.
- Optional additional O2 sensor bung for wideband O2 sensors.
- Optional EGT sensor bung for exhaust gas temperature monitoring.
- Compatible with both factory and aftermarket exhaust systems.
- Limited lifetime warranty.
- Made in the USA.
Restrictions in the factory exhaust system, particularly in the catalytic converter, can significantly limit power and performance. By replacing the restrictive factory catalytic converter with this high-flow metallic unit, you’ll experience improved turbo spool, better throttle response, and increased horsepower. This downpipe also features a flex section to reduce stress on the exhaust components, ensuring long-term durability, especially for lowered cars.
Fitment:
- BMW 230i (2016+)
- BMW 330i (2016+)
- BMW 430i (2016+)
- BMW 530i (2016+)
