Product Description

 

 

The Fabspeed Over‑Axle Link Pipes for the 718 GT4 RS / Spyder RS swap out the restrictive stock over‑axle exhaust plumbing for a freer‑flowing, mandrel‑bent stainless‑steel design — unlocking more power, reducing weight, and giving the flat‑six a deeper, more aggressive exhaust tone. The upgrade increases exhaust flow and reduces back‑pressure while maintaining bolt‑on simplicity. It’s an effective first mod to give your GT4 RS a rawer, more performance‑oriented sound and sharper throttle response without needing a full exhaust overhaul.

Fitment Notes

  • Compatible with Porsche 718 GT4 RS / Spyder RS (2022+).

  • Designed to replace factory over‑axle pipes — requires removal of stock pipes and direct bolt‑on installation. No cutting or welding required.

  • Select either resonated (muffled) or non‑resonated configuration depending on volume preference.

Included

  • Left and right over‑axle link pipes crafted from mandrel‑bent stainless steel. 

  • Optional resonator (if chosen) — straight‑through mini‑muffler style for reduced drone and smoother sound. 

  • All required mounting hardware and flanges for direct bolt‑on connection to the existing exhaust system.

Product Specs

  • Material: T‑304L stainless steel, mandrel‑bent tubing — built in-house by Fabspeed. 

  • Power Gain (stock configuration, no tune): +30 HP and +34 ft‑lb torque at ~4750 RPM (≈ +33 HP at the crank) according to Fabspeed dyno results.

  • Weight Savings: ~ 12 lbs (≈ 5.4 kg) lighter than the stock over‑axle assembly. 

  • Flow Improvement: Tubing is ~ 40% larger than OEM for maximum flow, reducing exhaust restriction.

  • Heat Shielding: Bi‑layer shielding with a stainless‑steel outer shell and ceramic‑fiber core, rated to handle continuous heat up to approx. 2400°F (1300 °C) — helps protect rear suspension components from heat soak.

  • Configuration Options: Resonated (quieter) or non‑resonated (louder, more aggressive) versions available. 

  • Fitment Design: CAD‑designed via 3D OEM exhaust scan for perfect bolt‑on fitment with factory mounting points.

Product Features

  • Significant Power & Torque Gain — The freer flow and reduced exhaust back‑pressure delivers real-world dyno gains even without tuning, improving mid‑range punch and throttle response.

  • Weight Reduction & Dynamic Benefit — Shedding roughly 12 lbs from the exhaust helps reduce unsprung/rotating mass, improving throttle feel, suspension response, and overall car agility.

  • Enhanced Exhaust Tone — The larger flow path and streamlined design give the 4.0 L flat‑six a more aggressive, GT‑inspired exhaust note — deeper and more pronounced than stock.

  • Improved Heat Management — The heavy-duty heat shielding protects rear suspension components (shocks, bushings) from excessive heat soak, ideal for spirited driving or track use.

  • Flexible Sound Profile — With the choice between resonated or non‑resonated configurations, the owner can tailor the exhaust character: a mature tone for street use or raw aggression for performance driving.

  • Bolt‑On, No‑Mod Install — Designed for direct replacement of stock over‑axle pipes — straightforward to install without cutting, welding or special tools.

  • Paved the Way for Further Upgrades — By improving exhaust flow and reducing restriction before the muffler stage, these link pipes lay the foundation for future exhaust, headers, or tuning modifications.
