About the Porsche 911

Sixty years of the same silhouette and the same rear-engined conviction, refined until it became the sports car by which all others are measured. Flat-six exhausts — a catalyst per bank on many — are core to how a 911 sounds and breathes.

We list 5 parts for the Porsche 911, spanning petrol models built between 1989 and 2001 across 3.4 and 3.6-litre engines. Coverage includes catalytic converters, and every part is matched against original fitment data.
