Powerhouse Amuse 100-V Saikou Titanium Valvetronic Exhaust

The Overtake 100-V Saikou Exhaust is a premium, full-titanium variable exhaust system engineered for the Nissan R35 GT-R. Produced by Powerhouse Amuse in Japan, this system is built to provide high-level performance and sound customization. It features a proprietary STTI titanium construction, including specialized titanium bolts, hollow hangers for reduced weight, and Nismo-esque titanium heat fins for optimal thermal management. At the core of the design is a 100mm main pipe paired with a custom 100mm flange, which eliminates the common size reduction between the y-pipe and rear section to maximize exhaust flow. The integrated remote-controlled valvetronic system allows the driver to adjust sound volume for daily driving at the push of a button on the included key fob. The exhaust system finishes with the signature Amuse B-tail gold ring tip design and laser-etched Overtake branding, delivering both a distinct aesthetic and a dynamic race-inspired sound profile across the entire RPM range.
