Track-ready, aero-optimized hardtop for your Lotus Exige S2 — boost airflow, cooling, and style.

Wide Ducted Hardtop – Series 2 Exige (2005–2011)

Product Overview

Engineered for the track and refined for the road, Kepla’s Wide Ducted Hardtop is a premium aerodynamic upgrade for the Series 2 Exige. Featuring a widened duct area compared to the standard model, this hardtop improves airflow and engine cooling while delivering an aggressive motorsport aesthetic.

Unlike the OEM Exige roof, which has a ducted look but lacks a true two-layer internal structure, this Wide Ducted Hardtop is designed with performance in mind. The stock roof allows air to flow into both the cabin and engine bay without a sealed path, making it only semi-functional. Our design can be adapted for motorsport use, where a fully ducted system is desired. This hardtop has two layers to make air flow directly into the engine bay.

Carefully designed to integrate with the S2 Exige bodyline, this version not only reduces weight but also enhances downforce and ventilation performance—perfect for high-performance driving and competitive builds.
