JCR Inconel Race Downpipes with HJS 200 CEL Cats – Porsche 992 Carrera / Turbo

Description
The Porsche 992 Carrera and Turbo models are already impressive in standard form, but the exhaust and downpipes still offer plenty of room for improvement. The JCR Inconel Race Downpipes with integrated HJS 200 CEL Race Cats replace the restrictive OEM downpipes and dummy OPF matrix with a lightweight, heat-resistant, and high-flowing alternative. This results in more power, faster spooling, and a more aggressive sound without compromising fitment or reliability.

Lightweight Design
Thanks to 100% Inconel 625 construction and clever engineering, these downpipes are more than 5.78 kg lighter than the OEM version. The weight reduction at the rear of the car directly contributes to improved balance and handling.

Direct Replacement
The JCR Downpipes are completely plug & play and fit directly onto the OEM mounting points and connections. No welding or modification is required. Simply install the new downpipes with the included mounting hardware.

HJS 200 CEL Race Cats
The restrictive factory catalytic converters and dummy OPF matrix are replaced by high-quality HJS 200 CEL Motorsport Race Cats. These provide a drastic improvement in flow and a noticeable performance boost. For cars without OPF monitoring, these downpipes generally do not cause a CEL and ECU tuning is not required.

Heat Management
The downpipes come standard with motorsport-grade Inconel heat shielding, which better manages temperatures and drastically reduces radiant heat to surrounding components. This not only protects the engineering but also ensures more consistent performance under heavy load.
