FlowFX Muffler 3in In Offset/Out Offset

The FlowFX Muffler 3in In Offset/Out Offset (Model 72198) from Flowmaster is a premium universal muffler engineered for automotive enthusiasts seeking refined exhaust tone without compromising flow efficiency. Designed for 3-inch inlet systems with dual 2.5-inch outlets, this muffler suits a wide range of street and performance builds where balanced acoustics and responsive engine breathing are priorities. Whether you're upgrading a daily driver or fine-tuning a weekend warrior, the FlowFX delivers the signature Flowmaster sound character that has earned respect in the modification community for decades.

Built from durable stainless steel construction, the FlowFX features an oval body design (14 x 9 x 4 inches) with a 20-inch length that integrates cleanly into most custom exhaust layouts. The offset inlet and offset dual outlets allow flexible positioning on tight frames and accommodate vehicles with unconventional mounting points—a critical advantage for swap projects or heavily modified chassis. Flowmaster's proven internal chamber technology minimizes backpressure while smoothing exhaust pulses, yielding a deep, aggressive tone that appeals to performance-minded drivers without excessive drone at cruise speeds.

This universal muffler is ideal for custom exhaust systems, engine swaps, and street rods where OEM fitment is impossible or undesirable. Its 11.4-pound weight and compact dimensions make installation straightforward for fabricators and seasoned DIYers with welding capability. Ensure your exhaust piping matches the 3-inch inlet specification and confirm dual 2.5-inch outlet clearance before ordering; professional installation is recommended to achieve optimal hanger alignment and prevent vibration. The natural stainless finish resists corrosion in harsh climates and delivers a polished, race-ready appearance.
