These are the same high-quality units used in HKS bolt-on exhaust systems. The Carbon-Ti muffler is available with a 170mm shell, 120mm tip size w/ 75mm inlet. Hi-Power Ti is available in 170 & 130mm. In addition to existing stainless Hi-Power Universal series, shell size 130mm shell, 94mm tip with 2 different pipe inlet sizes are now available. To expand the purpose of use, a stainless shell without a tip is also available.
HKS has incorporated this new race inspired muffler and piping design into many street applications, which offers a greater flow and higher-RPM power gains due to the less restrictive design. This is achieved by eliminating unnecessary bends for the straightest exhaust path. For turbocharged applications, the large and smooth exhaust flow allows greater exhaust velocity for better mid-range boost response and high-RPM power. Naturally aspirated vehicles can also benefit from greater exhaust flow capacity as engine tuning levels increase.
