Performance Sports Catalyst Front Pipe for BMW B58 Engines - Part No. 524241

Give your BMW B58 the response, tone and flow it deserves with this Supersprint 200-cell metallic sports catalyst front section. It is a precision, bolt-on replacement for the OE front pipe, with sensor bosses and brackets positioned to match factory locations for a clean, straightforward install.

Why this sports catalyst is a must-have

• 200-cell metallic substrate with a high precious metal loading for outstanding gas velocity, durability and heat management
• Generous core size engineered to cut restriction, sharpen turbo spool and boost mid-range punch
• Developed to minimise the chance of MIL or CEL warnings that cheap catalysts can trigger
• Premium flex section for long-term reliability and correct drivetrain movement
• Pre-welded oxygen sensor boss for an easy, tidy installation
• Ideal foundation for Stage 1 and Stage 2 ECU calibration and future hardware upgrades
• Direct swap geometry - OE-style brackets and sensor positions for hassle-free fitting

We have fitted this Supersprint sports catalyst to multiple customer B58 builds and our own development cars. Fitment is spot on, drivability is superb and the soundtrack is exactly what enthusiasts expect from a high quality catted front pipe.
