PORSCHE CAYMAN BOXSTER 982 718 EXHAUST MANIFOLD CATALYTIC

Porsche 718 / 982 Boxster / Cayman – Exhaust Manifolds with Catalytic Converters | Left & Right | 982131703 | OEM Specification | Direct Replacement

Restore the optimal exhaust performance, emissions compliance, and the extraordinary acoustic character of your Porsche 718 or 982 Boxster and Cayman with this genuine exhaust manifold set with integrated catalytic converters — left and right — part number 982131703 — precision-engineered, factory-grade exhaust system components of the highest quality that are absolutely critical to the performance, emissions compliance, and the extraordinary driving experience of the 718 and 982 mid-engine sports car. An outstanding replacement solution for workshops, specialist dealers, and Porsche 718 and 982 owners seeking genuine factory-grade exhaust manifolds and catalytic converters with complete confidence in authenticity, part number accuracy, and long-term performance reliability.
The exhaust manifolds with integrated catalytic converters — part number 982131703 — for the Porsche 718 and 982 Boxster and Cayman are among the most technically critical and most performance-significant components in the entire exhaust and emissions system of these extraordinary mid-engine sports cars. The exhaust manifolds are the first element in the exhaust gas path from the engine’s cylinder heads — precision-engineered components whose primary pipe geometry, diameter, and length have been meticulously calculated and refined by Porsche’s engineers to optimise exhaust gas scavenging, minimise back pressure, and maximise the breathing efficiency of the 718 and 982 engine at every point in its rev range, contributing directly and meaningfully to the power output, throttle response, and the characterful exhaust note that makes the 718 and 982 such extraordinary and emotionally engaging sports cars to drive.
The integrated catalytic converters mounted directly on the exhaust manifolds of the 718 and 982 are close-coupled high-flow units positioned as close to the engine’s exhaust ports as possible — a design approach that maximises the thermal efficiency of the catalytic conversion process by ensuring the catalytic substrate reaches its operating temperature as quickly as possible after cold start, delivering the fastest possible emissions compliance while minimising the flow restriction that more distant catalytic converter positioning would impose on the engine’s breathing. The genuine OEM part number 982131703 confirms these as the exact factory-correct components for the 718 and 982 application — ensuring correct primary pipe dimensions, correct catalytic substrate specification and precious metal loading, correct oxygen sensor boss positioning, and complete compatibility with the 718 and 982 exhaust system architecture and emissions management electronics.

The complete left and right set covers both sides of the 718 and 982 flat engine — providing a matched, perfectly consistent, and comprehensively specified exhaust manifold and catalytic converter solution for both cylinder banks in a single purchase, ensuring identical flow characteristics, identical catalytic performance, and identical emissions compliance on both sides of the engine for optimal performance balance and complete emissions system integrity. Whether you are replacing damaged, cracked, or contaminated exhaust manifolds, replacing failed or worn catalytic converters, carrying out a comprehensive exhaust system restoration, or restoring your 718 or 982 to full factory exhaust specification and emissions compliance, this genuine left and right manifold and catalytic converter set provides the definitive replacement solution.
