Description

The STREETPOWER Oval Muffler 4in inlet/outlet from VIBRANT PERFORMANCE is designed for street-driven vehicles that require a balance between performance flow and street-legal sound suppression. This direct-bolt muffler is perfect for enthusiasts who want a responsive exhaust character without excessive drone, making it suitable for daily drivers and weekend warriors.

The muffler features a 4-inch inlet and outlet, accommodating mid-size displacement engines. Its oval chamber design increases internal volume while minimizing exterior dimensions, allowing exhaust gases to expand and separate velocity before exit. This design effectively reduces backpressure while incorporating absorption material to control resonance frequencies that can cause interior cabin boom.

Ideal for trucks, muscle cars, and sport compacts, this muffler is a straightforward bolt-on upgrade. Mechanics and tuners often specify this muffler when building street systems that prioritize emissions compliance and neighborhood relations alongside throttle response.
