MagnaFlow 12249 Exhaust Muffler

When I was looking into this I just about went the muffler delete and install straight pipe route. Watching YouTube videos doesn’t give you a real comparison of sound levels though. I went with a MagnaFlow 12249 and I’m glad I did. It has a smooth throaty sound but not too loud. I spoke to a guy a while back that did the straight pipe and it was substantially louder than I would want. Hope this helps. 🛻💭

Love the sound on my 2016 F150 5.0. Kept the stock exhaust just had a shop cut out the muffler and weld this on. All they needed was a 2.5 to 3 inch adapter and some extra pipe to make up for the shorter muffler. Sounds great but not over the top!

Installed on my 16 f150. One reducer and a small piece of 2.5" exhaust pipe - a bit of welding and voilà! Any exhaust shop would install for you fairly inexpensively. It fit perfectly, looks great, and gives just enough extra grumble with the 5 litre that you know something has been done - but not loud enough to annoy the neighbours in the wee hours of the morning!

The PERFECT aftermarket muffler for the 5.0 f-150. After much research, and watching many YouTube videos of 5.0 f-150’s with this muffler, I decided to pull the trigger. The muffler arrived faster than expected, and I had a local muffler shop weld it on my truck in 40 minutes for less than $60.00. As for the sound, it couldn’t be a more perfect tone for me. There is a nice low rumble at all times, and it sounds aggressive when you lay into the gas, but it’s quiet at highway cruising speeds and during light acceleration. I’ve always loved the deep rumble of a V8, and this muffler lets that motor sing without pissing off my wife or being obnoxious in public. If you’re hoping to look tough by having the loudest and most obnoxiously truck and be that guy that everyone loves to hate, this isn’t your muffler. If you’re looking for a muffler that’s a very respectable step up from your stock muffler, and you love the low rumble of a powerful V8 without alerting the neighborhood to your presence, this muffler is absolutely perfect.

My son just bought a 2008 Infiniti G37 that has been modified and was insanely loud. It was catless and basically straight piped 3” (single exhaust), save for two resonators of some description that did seemingly very little. Uncertain how these would sound together, we ordered this Magnaflow 12249 muffler and a Vibrant Ultraquiet Resonator from Amazon. The resonator was installed In the middle and the muffler at the back. These are both straight-through designs. I have to say, the result was perfect. It has a good rumble, sounds great when you put your foot into it, but is not obnoxiously loud at any point. Very pleased with this product.
