Creative mind frees up the stress

As contrary to being called ‘The racing car on the public road’, many owners are not satisfied with the exhaust sound of GT3. Owners can enjoy racing taste to some extent even in its original style but we took it further to be in the school of GT1 sound, to free up the engine and to find the ‘natural exhaust sound’.

Through all the experiments and struggles, we now deliver the ‘ultimate exhaust sound’ with the best combination of sound quality and volume achieved at the highest level.
GT3 Exhaust System
Of particular note is the automatic switch-over system which changes from circuit mode (loud) to public sound (silent ? identical level as original exhaust system) mode with only a push of button. This enables owners to reduce the stress often caused by changing exhaust system ? starting engine in the wee hours of morning, warm-up operation in suburbs and parking at home in the midnight just to name a few.
Ultimate efficiency of engine exhaust Circuit / Public mode
Our development staff takes pride in being a professional group in terms of the complete knowledge of engine and exhaust system. Furious sound volume and beautiful dry tone often attracts the attention but, as the data of Chassis Dynamo shows, the most important element of exhaust system is obviously exhaust efficiency. Needless to say, the high performance of muffler itself is assured and when it’s combined with exhaust manifold, they improve the efficiency dramatically yet still ensure enough road clearance. (Each parts can be attached separately.)
  When faced with the reality of daily driving, the exhaust sound can become a headache for owners when considering the change of system. To solve the issue, this product comes equipped with switch-over exhaust system. By pressing a button at cockpit, the actuator controls the open / close of bulb, enabling owners to choose between circuit / public mode. (The level of exhaust sound in public mode is approximately the same as the original one.) You can go wild & loud or keep it smooth & low, it’s now totally up to you. This is for the owners who hesitated the change.
     
No less beautiful than Ferrari   Perfectly sculpted pipe
Exhaust system can sing beautiful soprano when exhaust efficiency is at the highest. ‘Rough and Bass’ would be the words to express the sound of normal Porsche whereas this product will have you hooked on a high pitch sound. The exhaust note that complex R-form pipe creates sure compares favorably with the one of Ferrari.   This four-tail-pipe is adopted to perfectly match rear bumper and rear under diffuser. Our unique system has two outside pipes used for straight exhausting in circuit mode while two other inside ones are used in public mode. Owners can also choose the material from 3 types, Titanium, Stainless and Ti/Sus Hybrid.
