Product Description

The Vibrant Performance 1147 StreetPower muffler is engineered for enthusiasts who want high exhaust flow with a more discreet appearance. Featuring a true straight-through perforated core, this muffler minimizes restriction to improve horsepower and torque while maintaining a deep, smooth exhaust tone. Its high-temperature flat black coating gives it a stealthy look, making it ideal for sleeper-style builds that avoid unwanted attention. 

With a 3-inch inlet and outlet in a center/center configuration, the 1147 is well-suited for custom exhaust fabrication projects. The oval body (5"x9"x15") and 20-inch overall length provide effective sound control without sacrificing flow. Built from durable T304 stainless steel and packed with multi-layer sound absorption materials, it delivers long-lasting performance in both naturally aspirated and forced induction applications.
