Skunk2 Racing 413-05-5030 MegaPower R Exhaust System for 4-Door Honda Civic Si

Skunk2's 70 millimeter MegaPower R exhaust system for the Civic Si sedan is constructed of T-304 stainless steel, is robotically TIG welded, and features CNC mandrel bends for a precise fit. Skunk2's cat-back, bolt-on MegaPower R systems are designed for naturally aspirated engines featuring higher compression, aggressive camshafts, and racing headers as well as for mild turbocharged applications that require more exhaust flow than Skunk2's 60 millimeter MegaPower exhausts provide.Featuring Japanese-spec, Super N1 styling, MegaPower R Exhaust systems generate more horsepower by optimizing engine airflow and volume through carefully selected, application-specific tubing lengths and diameters and increased wave scavenging effects for more horsepower.
