Product Description

Enhance the exhaust flow and sound of your BMW F80 M3 or F82/F83 M4 with the Milltek Sport Secondary Catalyst Delete Pipe. Engineered specifically for the S55 twin-turbocharged inline-six engine, this performance exhaust component replaces the secondary catalyst section to reduce exhaust restriction and deliver a more pronounced exhaust note.

Manufactured from premium T304L stainless steel, the Milltek Secondary Catalyst Delete Pipe features a 3-inch (76.2mm) diameter design that promotes efficient exhaust gas flow. By eliminating the restriction associated with the secondary catalyst section, this upgrade is designed to improve exhaust flow and enhance the overall sound characteristics of the vehicle.

The non-resonated configuration allows more of the S55 engine's distinctive exhaust character to be heard, particularly during acceleration and higher-RPM driving. When paired with a compatible Milltek Sport cat-back exhaust, the system provides a more aggressive exhaust experience while maintaining the quality and precision associated with Milltek's performance exhaust products.

Designed specifically for Milltek Sport cat-back exhaust systems, this secondary catalyst bypass is compatible with both factory BMW primary downpipes and Milltek Sport primary downpipes. Its precision-engineered construction provides direct integration with the intended exhaust configuration without requiring cutting or welding.

Milltek manufactures its exhaust components in the United Kingdom using high-quality materials and performance-oriented engineering. The T304L stainless-steel construction offers excellent corrosion resistance and durability under demanding exhaust temperatures.

For BMW M3 and M4 owners seeking increased exhaust volume, reduced exhaust restriction, and a more engaging driving experience, the Milltek Sport Secondary Catalyst Delete Pipe is an excellent addition to a compatible Milltek exhaust system.
