Description
The SOUL Performance Exhaust System replaces the restrictive factory rear muffler and the secondary valved flow path on the Porsche 992 GT3 and GT3 RS. Exhaust flows from the factory headers through SOUL’s cast transition cones, into 3 in tubing and a bespoke x-pipe, and out through 4 in tips. Without the factory valve programming, the full sound of the 4.0 liter flat six is available across the rev range, with tuned Helmholtz resonators added to smooth drone between 3,400 and 4,000 rpm.

Good to know
- Replaces the rear muffler and valved bypass only. Factory headers and catalytic converters stay, and SOUL states emissions requirements are unaffected. SOUL does not publish a CARB EO number for this system.
- Non-valved design: there is no factory valve control of the exhaust sound. SOUL compares the volume to earlier 997 and 991 center muffler bypass pipes.
- For a 2025 or later 992.2 GT3, order SOUL’s separate 992.2 version instead.
- Professional installation recommended. Installation is not included.
