Show original supplier description
The HKS Hi Power exhaust system is a classic JDM component, engineered for a direct bolt-on installation on 2006-2013 Lexus IS250 and IS350 models, including both RWD and AWD variants. This axle-back system features a straight-through muffler design, utilizing "Advantex" glass wool from Ownes Corning to provide an aggressive yet street-drivable sound profile. Constructed with a focus on performance, the system minimizes bends to optimize exhaust flow. The piping is made from robust SUS304 stainless steel, chosen for its strength and corrosion resistance, while the muffler section is also stainless steel. The exhaust tips measure 115mm, and the piping diameter is 60mm. All emissions equipment is maintained, ensuring compliance. HKS exhaust systems are manufactured in Japan, reflecting a commitment to quality and performance engineering. Most models include a removable silencer for adjustable sound levels.
