HKS SILENT Hi-POWER TURBO E-JZA70 1JZ-GTE

Constructed from SUS304 polished stainless steel, this HKS SILENT Hi-POWER cat-back exhaust system is built for the E-JZA70 with the 1JZ-GTE engine. This system replaces the factory muffler and piping from the catalytic converter back, offering an improved exhaust note and better flow compared to stock. The design focuses on reducing drone and keeping the sound comfortable for daily driving, even with a turbocharged engine, while still providing a noticeable sporty tone under acceleration.

The SILENT Hi-POWER series features a unique offset muffler chamber design and a specially developed Silent Chamber structure. This advanced internal baffling helps to suppress high-frequency exhaust noise, which is often the cause of cabin drone. The piping is 75mm in diameter, transitioning to a 120mm x 85mm oval tip, all made from durable SUS304 stainless steel that resists corrosion and looks good. This well-built system is designed to bolt directly onto the factory exhaust hangers, making installation straightforward for those familiar with exhaust work.

This cat-back system is a popular choice for owners looking to enhance their 1JZ-GTE's exhaust sound without the excessive noise or drone that can come with less refined systems. It's a solid option for improving the driving experience, offering a balance of performance and comfort. For installation, you'll typically want to have basic hand tools and possibly a lift or jack stands to safely access the underside of the vehicle. Refer to the manufacturer's installation instructions for specific details and any required hardware, though this system is designed to utilize factory mounting points.
