Review on MagnaFlow Exhaust Products 12249 Muffler by Chris Horton

is your muffler of choice when you want a smooth sound without absolutely NO hum at any speed. Magnaflow is up to the task. I researched F150Forums.com, listened to the video and am glad I chose this one. It won't wake the neighbors, but it will growl loudly if you step on it. The muffler shop simply cut out the old one, replaced it and welded it on. It's simple, I didn't take the full cat-back because I don't have that much money!
