STREETPOWER Round Muffle r 3.5in inlet/outlet

The STREETPOWER Round Muffler 3.5in inlet/outlet is a universal-fit exhaust component designed for operators and enthusiasts who demand reliable noise suppression without sacrificing performance. Built by Vibrant Performance, this stainless steel muffler serves as a critical component in custom exhaust systems where stealth and durability matter—whether for tactical vehicles, law enforcement fleet management, or purpose-built rigs requiring professional-grade exhaust treatment. The 3.5-inch center inlet and outlet configuration makes this muffler compatible with a wide range of applications where OEM or aftermarket exhaust piping uses standard 3.5-inch tubing.

This muffler features a 6-inch round body construction with a 20-inch overall length, engineered to balance acoustic attenuation with minimal backpressure—a critical concern in high-performance systems where excessive restriction degrades engine efficiency and throttle response. The polished stainless steel construction resists corrosion, salt spray, and thermal cycling, ensuring long service life in demanding environments including coastal deployments and high-temperature operational zones. The internal design employs proven chambering geometry to break up exhaust pulses while maintaining scavenging characteristics essential for naturally aspirated and forced-induction powerplants alike.

Tactical operators, fleet managers, and performance-oriented mechanics benefit most from this universal muffler when upgrading systems on non-OEM platforms or when original exhaust components have reached end-of-service life. Installation requires standard exhaust hanger hardware and basic hand tools; the 3.5-inch slip-fit design accommodates minor misalignment common in field conditions or retrofit scenarios. Weighing 9.955 pounds, the unit's mass distribution supports secure positioning without additional bracing, making it suitable for vehicles ranging from light tactical trucks to larger command-and-control platforms where discreet operation is required.
