200-cell high-flow sports catalyst for B58C PPF models

Release serious performance and flow from your turbocharged 3.0 straight six with this Wagner Tuning 200 CPSI catted front pipe. Built for petrol particulate filter equipped B58C vehicles, this performance catalyst reduces backpressure, improves turbo efficiency, sharpens throttle response and delivers stronger mid-range punch while maintaining a clean, refined finish in premium T304 stainless steel.

Part number: 500001037.200CPI

OEM reference: 18329897313

Key advantages

• T304 1.4301 stainless steel construction for durability and corrosion resistance
• Large 3.5 inch primary with adapter to connect to the factory system for a true bolt-on install
• Direct replacement fitment for the original front catalyst section
• 200 CPSI high-flow sports cat to reduce exhaust restriction and increase gas velocity
• Lower thermal load on the turbocharger for improved efficiency under sustained use
• Faster spool, crisper response and greater torque potential on OPF and GPF cars

We have installed this Wagner catted section in-house at MJ Modifications and customer feedback has been excellent on quality, fit and drivability across both BMW B58C platforms and the Toyota GR Supra A90.

Good to know

Only for vehicles equipped with an OPF or GPF. Because the original catalyst is replaced with a 200 CPSI sports catalyst, a warning in the DME may occur. ECU calibration may be required to avoid fault codes on some cars.
