After installation I had a drone inthe cab at cruising rpm. Called Magnaflow, ask how I can get rid of it. He recommended that I should of installed a cross over or a muffler before the Magnaflow muffler. When I asked why they do not recommend that, his reply was "some poeple like the drone in the cab. Now that I had the cross over installed, it made a huge difference on my 2010 4.6L Tundra. I would saved me some money and time, if I had it all installed at the same time.

Great sounding muffler, not to loud for every day driving but you know it's there when you step on it.

Wanted a better sound then stock out of my 2012 Dodge Ram 1500 Laramie but didn't want it obnoxiously loud. The Magnaflow 24" part number 12388 was the perfect solution for what i wanted. At idle the tone is deeper, at cruise it is barely noticable but when you step on the gas it gives you that satisfying rumble to let you know you got a hemi under the hood!!! Best part, my wife didn't even know i had it on until she saw the bank statement. Win for me and win for her!!
