Some of us know about Orque in Japan who do performance parts for the Fiat 500 Abarth and Alfa Julietta. These performance parts for the 4C look interesting. Which pioneer would like to install these and provide some feedback for the group???

Their HFC DP and catless DP look interesting. We don't know if there would be any O2 sensor related CEL or if you would need a specific/proprietary tune for these DP to fully take advantage. Other 4C race "experts" have stated that with track testing, a HFC or straight pipe does not yield of hp/tq to justify the cost and PITA install. There is also the increased and sometimes intolerable noise associated with a HFC or catless DP. Orque's pricing for the HFC DP looks tempting at 160000Y and catless DP at 90,000Y.
Product Description:
It is a sports catalyst & adapter which developed development of power-up and accelerator response top priority. A genuine catalyst for a 1750 cc multi-air engine has large resistance, and because piping shape leading to the front pipe is bad due to large size, it prevents smooth rotation of the turbine in a large high rotation area, resulting in large exhaust resistance. Therefore, we have greatly improved the efficiency by combining piping shape with high efficiency, layout design, high efficiency metal catalyzer. Suppressing the time lag of the turbo, realizing a sharp rise. Furthermore, it will contribute greatly to power-up by increasing overshoot. It also contributes to weight saving, and of course the exhaust notes change to lace more (Catalyst adapters may require O 2 sensor canceller installation). (The picture for Julietta)

Their triple blued tip Y-pipe exhaust with electronic bypass silencer looks interesting. Very JDM-ish but very Ferrari F40-ish. However, at 220,000, that's somewhat steep for just the Y-pipe although the product description hints at it being Titanium.
Product Description:
Italian super sporty seems to be the most charming 4C, but the exhaust note is just noise and the tail end design is unbelievable boring style. Therefore, triple pipe is arranged in the center in the center, the titanium part of the W ring which becomes the classic style of Oreka is adopted in the end part. Pipe layout short-straight and wide from the turbine greatly improves exhaust efficiency, contributing greatly to accelerator response and top-end growth.
Of course, although the main focus of the design is power up, it is equipped with a variable port system developed by a new idea that was not in the past muffler layout, with silencers placed only in the center pipe. When the exhaust pressure exceeds a certain line, the exhaust note increases the volume naturally with the variable port that increases efficiency. Since the sound quality is tuned to a racing-like clear tone, by a synergistic effect with power-up, a driving pleasure up a notch is produced. Team Oreka is absolutely confident about his performance.
While suppressing the volume at the time of idling, it is also a big appeal to play an alpha-like exhaust sound with the rise of rotation, but in the new model, while maintaining the power of the high revolution range, the volume (proximity measurement) at idle is set to 5 dB I reduced it.
