Description
A well-balanced sports muffler excels in ease of handling, comfortable sound, and a refined design.
Elegant Design
We've meticulously crafted a new tail for the stock WRX S4, adorning the bumper with a set of four exquisite titanium tails, two on each side.
Pleasurable for Everyday Driving
Experience a deep sports sound that accentuates the mid-high range while retaining focus on the low range. This perfect balance is achieved through meticulous consideration of pipe diameter, resonator, and silencer when replacing the main muffler. Whether for daily commutes or special occasions, driving will be an absolute delight. An internal partition structure within the muffler diminishes unwanted noise while adding depth to the sound.
Seamless Sound Flow
Despite its partitioned structure, this muffler achieves a seamless sound flow with 20% less exhaust resistance compared to the stock version.
Notes:
- The product includes the main mufflers only.
