Muffler 3.5in SS w/ Turn Down

The Muffler 3.5in Stainless Steel with Turn Down from Beyea Custom Headers is a premium exhaust component designed for builders and enthusiasts seeking refined performance and durability. This 3.5-inch diameter muffler serves as the final stage in a custom exhaust system, responsible for noise reduction, backpressure optimization, and heat management. The turn-down exit design directs exhaust gases downward and rearward, a classic configuration that prevents heat radiation onto downstream components and provides cleaner underbody aesthetics compared to side-exit alternatives.

Constructed from full stainless steel, this muffler resists corrosion and thermal degradation across diverse climates and driving conditions. The 3.5-inch inlet diameter matches modern high-flow exhaust systems, ensuring minimal restriction while maintaining acoustic control through Beyea's proven internal chambering design. At 2.9 pounds, the unit remains lightweight enough for performance applications without compromising structural rigidity. Stainless steel construction also simplifies long-term maintenance and preserves finish quality, critical for vehicles where exhaust visibility matters to the build aesthetic.

This muffler best suits custom-built vehicles, street rods, trucks, and performance platforms where precision exhaust engineering enhances both functionality and appearance. The turn-down orientation makes it ideal for installations prioritizing underbody clearance and component protection, particularly where traditional side-exit layouts create packaging conflicts. Installation requires proper mid-pipe or axle-back assembly integration; verify inlet diameter compatibility (3.5-inch) with your existing exhaust tubing before purchase. Beyea Custom Headers' reputation for quality ensures this component delivers consistent performance across years of service, making it a trusted choice for discerning builders and restoration shops.
