Overview
The MagnaFlow 12198 is a satin stainless steel muffler with a centered inlet that is 3 inches across and a dual offset outlet of 2.5 inches. The muffler is 100% stainless steel with lap-joint welded construction.
The straight-through design routes exhaust through a perforated stainless steel core wrapped in stainless mesh. Acoustical fiber fill is packed inside to keep the sound deep and smooth over time. The inlet and outlet differ in size, so check both ends against your pipe. It is a universal fit part, so no specific vehicle applies.

- Mixed tube sizes: 3-inch inlet and 2.5-inch outlet
- 100% stainless steel with lap-joint welds
- Perforated straight-through core

Choosing the right setup
With a universal fit muffler, the matching work falls to the pipes. Measure the tubing at both ends before buying, and compare the inlet position with where your pipe actually arrives under the vehicle. A centered inlet and a dual offset outlet change how the body sits, so test-fit the routing before final tightening. Routing often matters more than the muffler’s own shape.
Stainless steel resists corrosion well, but welds and hanger points are where wear shows first. Route the outlet so it clears the frame, fuel lines and spare tire carrier. Heat from the exhaust can dry out rubber isolators, so look at them during routine service. Re-check clamps after the first few drives, since new fittings can settle.
- Measure pipe diameter at both ends
- Check clearance around the body and outlet
- Re-check clamps after the first drives

Vehicle fitment
The 12198 is not matched to a year, make or model. It is sold as universal fit, so the tube sizes and port positions decide whether it works with a given exhaust.
Before buying, confirm the part fits your vehicle’s year, model and trim.
