BJG Custom Exhaust: Porsche 992 GT3/GT3 RS - Stainless Steel Valved Catback

A richer flat-six soundtrack, with control when you want it. The BJG Custom Stainless Steel Valved Catback gives the Porsche 992 GT3/GT3 RS a more expressive voice while retaining the flexibility of a valved exhaust. With the valves closed, the sound takes on a more restrained character; open them for a fuller, more assertive note as the revs rise.

Stainless-steel construction, purposeful routing and a polished finish create a premium rear-exhaust upgrade that complements the GT3's naturally aspirated character. The system focuses on sound and exhaust flow, with the final result determined by the vehicle, header configuration and calibration.

• Professional installation required

Choose Your Configuration

Catback Only: Valved rear exhaust; headers are not included.

Add Performance Racing Headers: Catback exhaust with matching race headers. Compatible ECU tuning is required.

Add High Flow Headers: Catback exhaust with matching high-flow catted headers. Confirm calibration and emissions requirements for your specific vehicle.

Fitment & Installation

Porsche 992 GT3/GT3 RS. Confirm model year, chassis, connection layout and valve-control compatibility before ordering. Header selection must match the vehicle and exhaust. The gallery shows a package configuration; headers are included only when the corresponding option is selected.

Race-header use restrictions: Not approved for public-road use. Race designation does not override emissions or anti-tampering laws, and tuning does not make emissions-delete hardware street legal. Confirm legal eligibility before purchase or installation. High-flow catalytic converters do not by themselves establish street-use approval.
