Performance Stainless Steel Catless Over Axle Pipes - Porsche 718 GT4 / Spyder / GTS 4.0L

Unlock a more aggressive exhaust character and freer-flowing exhaust path from your Porsche 718 GT4, Spyder, or GTS 4.0L with these Performance Stainless Steel Catless Over Axle Pipes. Designed for Porsche's naturally aspirated 4.0L flat-six platform, this pair replaces the corresponding factory exhaust sections with a less restrictive performance-oriented design.

Constructed from stainless steel and featuring external thermal shielding around key pipe sections, these over axle pipes are built for high-temperature exhaust environments while delivering a rawer, more pronounced flat-six exhaust note.

Important Notice

This is a catless performance exhaust component. Removal or replacement of emissions-control equipment may not be legal for road use in your region. This product is intended for off-road, motorsport or competition applications where permitted. Check all applicable local regulations before purchase or installation.

Care Guide

Regular Inspection: Periodically inspect the pipes, welds, flanges, fasteners and thermal shielding for looseness, damage or excessive wear.

Cleaning: Allow the exhaust system to cool completely before cleaning. Use a soft cloth with mild automotive cleaner suitable for stainless steel.

Avoid Harsh Chemicals: Do not use highly acidic, alkaline or abrasive products that may damage the stainless steel surface or thermal shielding.

Check Connections: Reinspect flange connections and mounting hardware after the initial heat cycles to ensure the system remains properly secured.
