DESCRIPTION
Bring a high-flow motorsport character to Porsche 991 GT3 models with this mirror-polished T304 stainless dual 3-into-1 equal-length long-tube header set.
The dual merge layout is designed for the high-revving naturally aspirated flat-six, supporting exhaust pulse scavenging and a smoother flow path. Precision TIG-welded T304 stainless construction and a mirror-polished surface provide a durable, distinctive finish. The headers were chassis-scanned for the specified 991.1 and 991.2 clearance, then designed as a direct bolt-on OEM replacement.
The set works with the OEM mid-muffler and most aftermarket cat-back exhaust systems, making it a focused upgrade for street performance and track-day builds.
