What material is the HKS SILENT Hi-Power exhaust made from?

This cat-back exhaust system is constructed from SUS304 stainless steel. This material is chosen for its strength and its ability to resist corrosion, which is important for exhaust components exposed to road conditions.

How does the 'Silent Chamber' design affect the sound?

The Silent Chamber structure is HKS's approach to reducing exhaust drone and overall noise levels. It helps to create a more comfortable sound inside the cabin during cruising speeds while still allowing for a sportier tone when you accelerate.

What parts are included with this cat-back exhaust system?

This HKS SILENT Hi-Power cat-back system includes the muffler assembly and the exhaust piping that runs from the factory catalytic converter back to the muffler. It is designed to connect directly to your stock catalytic converter.

Product Details

This is the HKS SILENT Hi-Power cat-back exhaust system specifically made for the CZ4A 4B11 Lancer Evolution X. If you're looking to change the sound and performance of your Evo X, this system is designed to offer a more refined exhaust note compared to louder, more aggressive systems, while still improving exhaust flow.

HKS has engineered this cat-back system using SUS304 stainless steel for the piping and muffler construction. This material is well-known for its strength and resistance to corrosion, which is important for an exhaust system that's exposed to the elements. The muffler features HKS's unique Silent Chamber structure, which helps to reduce drone and keep the sound at a more comfortable level, especially during cruising. This design aims to balance a sportier tone under acceleration with a quieter experience on the highway. The piping diameter is optimized for the 4B11 engine to help improve exhaust gas evacuation without sacrificing low-end torque. Installation is designed to be a direct replacement for the factory cat-back section, meaning it bolts up to the stock catalytic converter and uses factory mounting points.

This cat-back system includes the muffler and the piping from the catalytic converter back. You'll want to ensure your factory catalytic converter is in good condition, as this system is designed to connect to it. The result is an improved exhaust note and potentially better throttle response, all while maintaining a more subdued sound profile than many aftermarket options.
