Enhance the performance and sound of your BMW B58 Gen 2 engine with the CRT Performance 200 CPSI Sport Catalytic Downpipe. Designed exclusively for European models equipped with OPF/GPF, this high-performance exhaust upgrade reduces backpressure, improves turbo response, and delivers a deeper, refined exhaust tone — all while maintaining moderate emissions output.

Key Benefits

• Reduced Backpressure – Faster turbo spool and sharper throttle response.

• Weight Savings – Lighter than OEM catalytic assemblies for improved agility and performance.

• Optimized Flow – Smooth mandrel bends minimize turbulence for efficient exhaust gas velocity.

• Refined Sound – Deep, sporty tone without the harshness of a fully decat system.

• Balanced Emissions Control – 200 CPSI high-flow catalyst offers a smart balance between performance and eco responsibility.

Materials & Construction

• Handcrafted from 304 Stainless Steel – Exceptional heat and corrosion resistance.

• CNC-Machined Flanges – Precision-fit connections to turbo and exhaust system.

• 200-Cell High-Flow Catalyst – Maximizes performance while maintaining essential emission reduction.

• TIG-Welded by Hand – Ensures unmatched strength, reliability, and premium finish.

Testing & Reliability

Each CRT downpipe is track- and road-tested to verify consistent performance, flow efficiency, and durability under the most demanding conditions.
