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 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
Available with decat pipes for optimum performance and sound, or with 100 or 200 cell HJS HDPE catalysts. The largest gain with decats is 38hp and 55nm. 100 cell and 200 cell catalysts produce 20hp, and 16hp respectively.
