Vibrant Performance Streetpower Oval Muffler 1137, 4-Inch Center Inlet and Outlet

The Vibrant Performance Streetpower Muffler, part number 1137, is a universal exhaust component designed for performance street applications. It features a 4-inch center inlet and a 4-inch center outlet to support compatible exhaust systems while maintaining a clean, straightforward installation layout. The oval body is constructed from stainless steel and finished with a polished surface for durability, corrosion resistance, and a professional appearance beneath the vehicle.

Feature: Reversible design allows the muffler to be installed in either direction, providing added flexibility when routing or configuring an exhaust system. Its compact oval profile is well suited to a variety of custom and replacement applications where space and exhaust flow considerations are important. As a universal muffler, fitment may require fabrication, adapters, or additional exhaust hardware depending on the vehicle and system configuration.

Feature: Stainless steel construction helps withstand exposure to heat, moisture, road debris, and exhaust-related corrosion, while the polished finish complements other polished exhaust components. The Streetpower design is intended for enthusiasts seeking a practical muffler solution for a custom performance exhaust system. Verify inlet and outlet placement, pipe diameter, available clearance, and local noise regulations before installation.

Feature: The Vibrant Performance 1137 muffler is supplied as an individual unit and is not restricted from air shipment. Its 20-inch body length and oval form provide a balance of usable packaging space and exhaust-system compatibility without relying on a vehicle-specific fitment. Professional installation is recommended to ensure secure connections, proper alignment, adequate clearance from heat-sensitive components, and leak-free exhaust performance.
