Ceramic Euro 5 Catalytic Converter High Flow 93x80mm for BMW E46
Fully compliant with Euro 5 emissions standards, this high-flow ceramic catalytic converter delivers consistent exhaust purification while minimizing backpressure. Engineered as a direct interchange for factory units—including common installations on BMW E46 models—the 400 CPSI ceramic honeycomb core efficiently neutralizes harmful gases without choking engine airflow. The precise 93 mm diameter and 80 mm length integrate seamlessly into standard exhaust line routing, replacing worn or degraded original equipment converters.
Benefits & Practical Tips
- Balanced Flow Dynamics: The 400 CPSI substrate optimizes gas residence time, maintaining steady throttle response and idle stability when paired with stock engine mapping.
- Pre-Install Measurement Check: Verify your existing pipe spacing before cutting. A manufacturing tolerance of ±0.1 mm is standard and will not impact function, but confirming clearances prevents post-weld alignment shifts.
- Consult Our Installation Guide: Proper exhaust fusion requires clean pipe edges and even heat distribution. Review our store’s step-by-step welding video to secure joints before full pass-through welding; loose fittings or movement during repair compromise safety.

Installation Notes & Limitations
This converter is designed strictly for replacing original equipment catalyst sizes and is not rated for use on performance-modified exhaust systems or turbocharged downpipes. Professional fabrication tools and experience are strongly recommended. Please note that we do not assume liability for component displacement, joint failure, or exhaust leaks caused by improper welding techniques, misaligned mating flanges, or handling after installation.
