The result is increased horsepower, torque and improved throttle response. Optimized Tube Lengths: Tube lengths are optimized for true pulse control technology which improves flow and performance. 3\/8\" Laser-Cut Flanges: These headers come with 3\/8\" thick laser-cut head flanges that are designed to match the head port for a leak-free seal. Mid-Pipe: Dual High Flow Catalytic Converters: This system utilizes 400 CPSI (cell per square inch) 48-state legal catalytic converters are used for maximum flow. Construction: Constructed of mandrel-bent dual 1.625\" stainless steel piping which transitions into single 2\" piping to reduce back pressure and improve flow. Leak-Free Seal: High quality OE style flanges and band clamps are used for a complete 360 degree sealing surface. Hassle-Free Installation: The performance header and Mid-Pipe are designed to fit in the stock location with an included extension pipe which allows this system to fit without modification. This system incorporates OE style hangers, flanges and includes O2 extensions for a hassle-free installation. *All aFe headers and Mid-Pipe systems are engineered and manufactured in our Corona, California manufacturing facility.\nTwisted Steel Long Tube Header \u0026amp; Mid Pipe 304 Stainless Steel w\/ Cat BMW M3 (E36) 96-99 L6-3.2L S52\n\u003cul\u003e\n  \u003cli\u003eIncorporates High Flow 400 Cell Cat Converters For Improved Flow\u003c\/li\u003e\n  \u003cli\u003e3-to-1 Mitered Collectors Eliminates Flow Blocking Turbulence\u003c\/li\u003e\n  \u003cli\u003e100% Hand TIG-Welded Constr.

Designed for the E36 M3 equipped with the 3.2L inline-six S52 engine, this system combines optimized long tube headers with high-flow catalytic converters to improve exhaust flow, throttle response, horsepower, and torque. The 3-to-1 mitered collectors help reduce turbulence and maintain exhaust velocity, while optimized tube lengths support effective pulse control.\u003c\/p\u003e\u003cp\u003eConstructed from 304 stainless steel, the headers and mid-pipe use mandrel-bent tubing for smooth internal flow and long-term durability. The system includes 400-cell catalytic converters and is EPA compliant for applicable use. Its 3\/8-inch laser-cut head flanges are designed to provide a precise, leak-resistant connection, while OE-style flanges, hangers, and band clamps create a complete 360-degree sealing surface. The dual 1.625-inch tubing transitions into 2-inch tubing to help reduce back pressure and support improved exhaust performance.\u003c\/p\u003e\u003cp\u003eThe aFe Twisted Steel system is engineered for a hassle-free installation in the stock location. An included extension pipe and oxygen sensor extensions help accommodate the original vehicle layout without modification. All aFe headers and mid-pipe systems are engineered and manufactured in Corona, California. This product fits 1996, 1997, 1998, and 1999 BMW M3 models with the 3.2L S52 inline-six engine.
