BMW N55 200 CPSI HJS Sports Catalyst Front Pipe for F87 M2, F22 F23 M235i, F30 F31 335i July 2013 onward, F32 F33 435i

Unlock sharper response and stronger mid-range punch from your N55-powered BMW with this Fabspeed sports catalyst assembly. Built around a genuine 200 cpsi HJS motorsport core, this free-flowing front cat section reduces back pressure, speeds up turbo spool and delivers a deeper, richer soundtrack while retaining road manners. It is a direct-fit replacement for the factory front cat section and integrates cleanly with the stock system or most performance exhausts.

Highlights

• 200 cpsi HJS motorsport catalyst for excellent flow and durability
• Direct-fit to the turbo outlet and factory system with no fabrication required
• Typically does not illuminate the engine warning lamp when used as intended
• Precision CNC-machined flanges and jig-built construction for repeatable fit
• Pressed relief section for clearance on M235i applications
• Refined sound with more character than stock and without the harshness of a decat
