Rumble Muffler 3in In/ 2.25in Out

The MagnaFlow Rumble Muffler 3in In / 2.25in Out (R20422) is a performance exhaust silencer designed for automotive enthusiasts who desire an aggressive sound without excessive volume. This muffler is particularly suitable for vehicles equipped with larger aftermarket exhaust systems, providing a deep rumble characteristic of modern muscle cars and trucks.

Featuring a straight-through chambered design, the Rumble Muffler effectively manages exhaust flow and minimizes backpressure, making it compatible with both naturally aspirated and forced-induction engines. The 3-inch inlet is designed to fit standard performance downpipes, while the 2.25-inch outlet allows for tailored acoustic tuning, reducing drone frequencies during cruising.

This muffler is ideal for both carbureted and fuel-injected applications where sound quality is prioritized. However, fitment should be verified with your specific vehicle's year, make, and model to ensure compatibility with existing exhaust systems.
