Product Description

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

Capitalising on the design innovations and success of our 996 and 997 range, the starting point for designing the 991turbo exhaust had been set high. Our trademark perfect x pipe geometry, harmonically tuned silencer geomtery, Inconel 625, and our proprietry acoustic silencer packing materials result in a system that has become famous for that perfect sound. Zero drone, and a raised pitch raucious incindiary howl in higher rpms and hard throttle. The design is so perfect, that you can even run 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.
