The seventh incarnation of the 911, the 991 turbo has taken some strikingly beautiful evolutionary steps. A wider wheel base, and improved axel to engine geometry significantly improve the weight distribution and cornering stability. additional composites and aluminium to further reduce weight, even the exhaust has been somewhat improved over the 997. So how much could we really improve over the factory exhaust? Quite simply remarkably!

THE SOUND

Capitalizing on the design innovations and success of our 996 and 997 range, the starting point for designing the 991 turbo exhaust had been set high. Our trademark perfect x pipe geometry, harmonically tuned silencer geometry, Inconel 625, and our proprietary acoustic silencer packing materials result in a system that has become famous for that perfect sound. Zero drone, and a raised pitch raucous incendiary howl in higher RPMs and hard throttle. The design is so perfect, that you can even run catless versions silently at cruising speeds, only unleashing that howl when you drive the car hard.

During development there were some clear evolutionary design steps that we could incorporate. The secondary tail pipe allowed us to integrate an effective gas overflow system. The concept was conceived at the fluid dynamic modelling stage, and effectively works to cut low rpm noise, while allowing an effective increased cross section at higher RPMs producing a more accentuated Jekyll and Hyde personality, and slightly broader torque curves.

PERFORMANCE

Final Data on exact power figures is still being collated, but preliminary testing indicates a maximum power gain for the de-cat variant in the region from 35-45 WHP and 55-65 Nm torque.

Available with a variety of HJS catalysts, in either 100 cell 200 cell, HDPE perforated foil.

ROSS SECTION

De-cat cross section 70mm OD specifically chosen for a balance of peak torque and power.

Silencer section, cross section 65mm OD and 44mm OD overflow.

Catalysts come in a variety, from 108mm OD to 127mm OD.
