Performance and compliance can finally exist together.

STRATEC Systems™ is proud to introduce our new line of 400 Cell EPA-Compliant Downpipes, engineered for enthusiasts who want improved exhaust flow while maintaining a more environmentally responsible setup.

What Makes a 400 Cell Downpipe Different?

Traditional high-flow downpipes often use lower cell-count catalytic converters designed primarily for maximum airflow.

Our 400-cell design provides:

• Improved emissions control
• Better exhaust flow than restrictive factory systems
• Enhanced throttle response
• Improved turbocharger efficiency
• Reduced restriction compared to many OEM catalytic converters

Create a downpipe that delivers improved performance while maintaining a more refined and responsible approach to emissions management.

These systems are ideal for customers seeking a balance between performance, drivability, and everyday usability.
