Header 4-1 Performance Mazda Skyactiv

What is it?

The Skyactiv 4-1 Header replaces the stock exhaust manifold and catalytic converter on Mazdas with the Skyactiv 2.0 and 2.5-liter engines (non-turbo) since 2015 (BM-BN-BP). Its high-flow 4-1 design eliminates exhaust system restrictions, allowing gases to escape more quickly. Made from high-grade stainless steel, this header arrives plug and play, requiring no cutting or modifications.

What benefits does it bring?

• 🚗 Power Increase: Gains of up to 12 HP at the wheels have been recorded on fully stock vehicles.
• 🌰 Improved gas flow: The 4-1 design reduces back pressure and improves torque and engine response.
• 🔧 Plug and play installation: includes a lambda probe port and mounts using the original points, without modifications.
• 🎵 Sporty sound: By removing the catalytic converter, the exhaust sound is deeper and more aggressive, without annoying resonances.

Compatibility and specifications

• Compatibility: Mazda 3 / 6 with Skyactiv 2.0 and 2.5 engines (non-turbo) from 2015 onwards.
• Dimensions: 80 × 40 × 25 cm.
