Overview
The MagnaFlow 11216 is a satin stainless steel muffler with a 2.5-inch inlet and a 2.25-inch outlet, both centered. It is a straight-through design, so exhaust gas moves directly through the core.
Lap-joint welds hold the stainless steel case together, and a perforated core wrapped in stainless mesh runs through the middle. The muffler is packed with acoustical fiber fill that helps keep the sound smooth and deep. It comes with a lifetime warranty.

Matching a reduced outlet
A muffler with a smaller outlet than inlet narrows the path as gas leaves the body. The change can add a small amount of back pressure, which is one reason the tailpipe end deserves as much attention as the front connection. Work out where the step falls before cutting the old pipe.
When you plan the tailpipe, keep the joint short and straight where possible, and avoid sharp bends right after the outlet. Use a reducer only if your pipe is designed for it, since a poor match can leak or rattle. Clamp both ends with even pressure and keep the connection clear of the body.
Inspect the joints after the first week of driving. Look for soot streaks, loose clamps and any sign of wear where the stainless shell meets the pipe. Exhaust noise that suddenly changes often points to a leak at a connection rather than a fault in the muffler itself.
- Measure both ends before cutting
- Recheck clamp tightness after the first drive

Vehicle fitment
It is universal fit and no vehicle is named. The 2.5-inch inlet and 2.25-inch outlet must match your pipe on both ends, so measure before buying and confirm fit for your vehicle’s year, model and trim.
Confirm your vehicle’s year, model and trim before ordering.
Installation notes
The outlet is smaller than the inlet, so check that the outlet pipe diameter matches the tailpipe section you plan to connect.
What’s included
