The dBX Muffler 3in In/Out 6in x 14in by FLOWMASTER is a premium performance exhaust component designed for builders and enthusiasts who seek refined sound control without compromising exhaust flow. This muffler effectively balances aggressive exhaust tone with street-legal decibel levels, making it ideal for upgrades on muscle cars, trucks, and high-displacement engines.

Featuring a 3-inch inlet and outlet, the dBX Muffler optimizes exhaust gas velocity and backpressure management across mid to high-RPM ranges. Its construction includes FLOWMASTER's signature sound-deadening internal chamber design, which contributes to its reputation for delivering measurable noise reduction while maintaining power output. The muffler is built with durable stainless or aluminized steel to resist corrosion in harsh conditions.

This muffler is suitable for a wide range of applications, from street-driven daily drivers to track-focused vehicles where noise ordinances or personal preference require a quieter exhaust signature. Its straightforward bolt-on design accommodates 3-inch exhaust piping without the need for welding or custom fabrication, making it a practical choice for both weekend warriors and professional shops.
