JCR Inconel Race Manifolds & Titanium Link Pipes (Non Silenced / OPF Delete) Porsche 718 GT4 RS / Spyder RS

JCR Inconel Race Manifolds & Titanium Link Pipes (Non Silenced / OPF Delete) – Porsche 718 GT4 RS / Spyder RS

The Porsche 718 GT4 RS and Spyder RS have raised the bar for driving experience, but the sound and breathing of the engine remain severely restricted by the standard exhaust configuration. The combination of a restrictive manifold and the OPF (Over Axle / Link Pipes) pipes chokes the potential of the high-revving 4.0L GT3-derived engine.

The JCR Inconel Race Manifolds & Titanium Link Pipes (Non Silenced) completely replace these OEM parts, opening the way to maximum performance and a pure motorsport sound. Thanks to the combination of 100% Inconel 625 manifolds and 100% Titanium link pipes, weight is drastically reduced, flow is optimized, and a raw, GT3-worthy exhaust note is created. This is the most aggressive and lightweight configuration – ideal for owners who want to get the most out of their GT4 RS, both on the road and on the track.

Direct Replacement & Modular Design
This set is a complete plug & play replacement for the OEM manifolds and OPF pipes. No welding or modifications needed – simply remove the original parts and replace them.
The modular design makes it easy to switch to other configurations later (Silenced or Race Cat link pipes) without having to replace the entire set.

Motorsport-level Heat Management
The Titanium Link Pipes feature Inconel heat shielding as used in the highest class of motorsport. During intensive track tests, we saw a consistent drop of 15–20°C in rear tire temperature, which translates to better performance and longer tire life.

Non-Silenced Design
The Non Silenced version delivers the most extreme sound in the range. Completely open, raw and uncompromising – for those who want the true racing experience.

Lightweight & Performance Gain
Together, the Inconel manifolds and Titanium link pipes provide an impressive weight saving of –11.94 kg (26.34 lbs) compared to the OEM set. In combination with the improved gas flow, this delivers noticeable improvements in throttle response, torque and acceleration. During 100–200 km/h measurements on the track, clear time gains and torque improvements were recorded.
