Overview
The MagnaFlow 12255 is a satin stainless steel muffler with 2.25-inch inlet and outlet tubes, a centered inlet and an offset outlet. It is 100% stainless steel with lap-joint welds for a solid, durable body.
Its straight-through perforated core is wrapped in stainless mesh and packed with acoustical fiber fill that keeps the tone smooth and deep. Nothing ties the 12255 to a specific car or truck, so it is a universal fit muffler and the 2.25-inch tube size decides the match.

- Acoustical fiber fill for a smooth, deep sound

Before you buy
Universal fit mufflers depend on the exhaust around them more than on any single vehicle name. Start by measuring the existing pipe diameter, then compare it with the 2.25-inch tubes. The centered inlet and offset outlet also decide where the body can sit, so picture the route before committing to a purchase. A quick test fit saves time later.
Stainless steel bodies hold up well, but hangers and clamps are the parts that tend to wear first. Rubber isolators can crack from heat, and clamps can loosen as the pipe moves. Inspect them at routine service and replace worn pieces before they let the muffler sag or rattle against the body.
- Check pipe diameter before buying
- Look at outlet clearance under the vehicle
- Inspect rubber isolators at service

Vehicle fitment
The 12255 is not matched to any year, make or model. It is sold as universal fit, so its 2.25-inch tubes and the offset outlet must be compared with the exhaust it will join.
Compare the mounting points with your existing system, and verify fit for your year, model and trim before buying.
What’s included
