Product Description

Unleash the full, pure voice of your Porsche 718 GT4 / GTS / Spyder’s 4.0L flat-six with these Over Axle Pipes (OAP) from Forza Motor Works. By replacing the restrictive factory over-axle section, these pipes deliver improved flow, reduced weight, and a richer exhaust tone without needing a full exhaust swap. With robust heat shielding built in, they protect surrounding components while amplifying throttle response and character. For drivers who demand both performance and acoustic presence, this is a high-impact upgrade.

Fitment Notes

  • Fits 2020+ Porsche 718 Cayman GT4, GTS 4.0, and Boxster Spyder / GTS 4.0 in North American spec.

  • Compatible with factory muffler / rear section; mates easily to OEM or aftermarket rear systems designed to accept the stock OAP. 

  • Not intended for non-4.0L (turbo) 718 models

  • Designed to retain thermal protection via heat shielding to avoid excessive heat soak to nearby components

Product Specs

  • Material: T-304 stainless steel

  • Weight savings: ~11 lb lighter than OEM sample in comparable applications

  • Power gain: ~25 hp across the rev range over factory OAP

  • OPF delete design (removes particle filter restriction) without triggering a check engine light in North American cars

  • Heat shielded design to protect axle, brakes, suspension from radiant heat

Product Features

  • Performance sound & presence — enhances the raw tone of the 4.0L flat-six with more volume and clarity

  • Lightweight, free-flowing design — reduces backpressure and exhaust mass compared to stock OAP

  • Robust heat shielding built in — protects surrounding components from excessive temperature rise

  • OPF delete / filter removal — removes factory restrictions to free up airflow without creating a CEL (for NA North American cars)

  • Bolt-on installation — mates directly to factory-style interfaces, no cutting or fabrication required

  • Material options — choose stainless steel or upgrade to titanium for lighter weight and alternate tonal character
