The Hybrid Megaphone Evolution is a full stainless steel performance exhaust system engineered for both aesthetics and performance. Every component—from the main muffler canister and precision-formed piping to the internal resonators, silencers, hangers, and brackets—is constructed from high-grade SUS304 stainless steel for superior corrosion resistance and longevity. This system blends advanced acoustic tuning with race-proven performance, offering enhanced durability, confidence-inspiring reliability, refined exhaust notes, and substantial gains in high-RPM power output.

-
Full SUS304 Construction: Ensures exceptional corrosion resistance, thermal stability, and structural integrity across all components.
-
TIG Welded Assembly: Precision TIG welding throughout the system provides optimal strength, clean aesthetics, and improved durability under high-stress conditions.
