Description
SOUL built this system for 991.1 Carrera owners who find the factory sport exhaust underwhelming, aiming for a Jekyll and Hyde character. With the valves open, exhaust takes a straight path through larger diameter tubing, smooth radius bends and an X-pipe crossover, which SOUL says improves throttle response over the restrictive factory sport exhaust and gives a Cup car inspired sound with more crackles and burbles on deceleration. With the valves closed the factory side mufflers keep the tone refined and drone low. The 991.1 Carrera has a natural drone range at 3,000 to 3,500 rpm once higher flowing parts are added, so SOUL engineered Helmholtz resonators (anti-drone tubes) into the system to filter it and to smooth the closed to open valve transition on PSE cars. SOUL also designed it to stay pleasant when paired with aftermarket headers.
Key features
- Straight, unrestricted 2.5 in path to the tips with the valves open
- X-pipe crossover smooths the sound with the valves open or closed
- Helmholtz resonators tuned for the 3,000 to 3,500 rpm drone range
- Works with the factory PSE valve controls; non-PSE S and GTS cars use the valve controller included in the non-PSE options
- Reuse the factory tips or choose SOUL bolt-on tips in Polished Chrome or Black Chrome
- Direct bolt-on, with installation instructions and new high grade hardware included
- Fixture-tested for fitment and foam packed; SOUL lifetime warranty for street and track use

Good to know
- Choose the option to match the car: PSE cars reuse the factory PSE controls; S and GTS cars without the PSE button have vacuum valves and need one of the valve controller options.
- SOUL notes the valve controller is harder to fit on non-PSE cars: a power source must be found and tapped, vacuum lines run and the rear bumper removed.
- SOUL publishes no emissions statement or CARB EO number for this system; check local emissions and noise rules before fitting.
- Professional installation recommended, especially for non-PSE cars; installation is not included.
