This system is built to perform—and built to last. Crafted from premium T304 stainless steel, the S5277304 offers unmatched corrosion resistance and durability, making it the ideal choice for drivers who demand long-term performance and a polished look. The system features smooth mandrel-bent tubing, ensuring optimal exhaust flow and a refined, moderate tone that turns heads.
