9m Over Axle Pipes – Porsche 718 GT4 / GTS 4.0 / Spyder
High-performance over axle pipes for Porsche 718 GT4, GTS 4.0 and Spyder. Designed to enhance exhaust flow, increase sound character, and reduce weight for a sharper driving experience.
Full Product Description
The 9m Over Axle Pipes for Porsche 718 GT4, GTS 4.0 and Spyder are engineered to unlock the full character of the 4.0L flat-six engine by improving exhaust flow and delivering a more aggressive, motorsport-inspired sound.
Replacing the restrictive factory over axle sections, these pipes reduce backpressure and optimise exhaust gas flow, resulting in improved throttle response and a more engaging driving experience. The result is a sharper, freer-revving engine with a noticeably enhanced exhaust note across the rev range.
Manufactured from high-grade stainless steel, the system offers excellent durability and resistance to heat and corrosion, making it suitable for both fast road and track use. Precision-engineered for a direct fit, installation is straightforward with no modification required.
Whether paired with a stock rear silencer or an upgraded exhaust system, the 9m Over Axle Pipes deliver a significant increase in sound presence while maintaining OEM-level fitment and reliability.

Why Upgrade Over Axle Pipes?
The factory over axle section is a key restriction point in the exhaust system. Upgrading to performance pipes improves exhaust scavenging, reduces weight, and unlocks a more authentic flat-six sound — especially noticeable in mid to high RPM ranges.
