MagnaFlow D-Fit Muffler 409 SS 3in 17-19 Ford F150 Raptor 3.5L

This MagnaFlow D-Fit Muffler Replacement Kit is designed specifically for your 2017-2021 Ford F-150 Raptor with the 3.5L engine. What you get in this kit is the MagnaFlow muffler itself, ready to bolt into place. It's a straightforward way to swap out the factory muffler for a unit that lets your truck breathe a little easier and sound a lot better, all while keeping your existing exhaust piping and tailpipe intact. This means installation is generally simpler, connecting right up to the stock points on your truck.

The heart of this kit is MagnaFlow's straight-through muffler design, built with 409 stainless steel for solid durability. The main piping is 3 inches in diameter and features mandrel bends, which helps maintain consistent diameter throughout the bend for improved exhaust flow compared to crush bends. This design is engineered to produce a moderate exterior sound level and a mild interior sound, giving you that signature MagnaFlow rumble without being overwhelming. The construction uses CNC precision robotic manufacturing, ensuring a well-built part that fits right.

This kit is a popular choice for F-150 Raptor owners looking for a noticeable improvement in exhaust tone and performance without a full cat-back system. The 409 stainless steel construction means it's built to resist corrosion, and it comes with a limited lifetime warranty on construction from Magnaflow, so you can feel confident about its longevity.
