Product Details
The MBRP Armor Lite Universal Chambered Muffler (GP122107) is a performance exhaust component designed for enthusiasts looking to upgrade their exhaust system with durable construction, controlled exhaust sound, and a versatile single-inlet, dual-outlet configuration. Manufactured from aluminized steel and featuring an internal chambered design, this muffler provides an excellent solution for custom exhaust fabrication, performance exhaust upgrades, and replacement applications.
Engineered to balance exhaust flow with effective sound management, the MBRP GP122107 utilizes internal chambers to shape exhaust acoustics while allowing exhaust gases to travel through the muffler assembly. This configuration is well suited for enthusiasts who want a more controlled exhaust tone without relying on an unrestricted muffler design.
The muffler features a 3-inch inlet and dual 2.5-inch outlets, making it particularly useful for custom exhaust systems that transition from a single larger-diameter exhaust pipe into two separate tailpipe sections. This configuration provides flexibility when designing dual-exit exhaust systems for performance vehicles, custom builds, and modified street applications.
Constructed from aluminized steel, the GP122107 offers a practical combination of durability, corrosion resistance, and value. The aluminized coating helps protect the underlying steel from corrosion caused by moisture and normal exhaust exposure, making it a cost-effective alternative to stainless steel exhaust components.
Its cylindrical body measures approximately 6 inches in diameter and 20 inches in length, providing a substantial internal muffler chamber while maintaining a straightforward design for integration into compatible exhaust configurations.
As part of MBRP's Armor Lite product lineup, this universal muffler is designed for applications where dependable construction, exhaust sound control, and affordability are important considerations. It can be used in custom exhaust systems or as a replacement component when the required dimensions and exhaust connections are compatible.
Whether completing a custom Honda or Acura exhaust system, fabricating a dual-exit exhaust configuration, or replacing a damaged muffler, the MBRP GP122107 delivers the quality, versatility, and performance-oriented construction expected from MBRP.
