Review on MagnaFlow Exhaust Products 12586 Muffler by Gary Hall

I installed it on an '05 Tundra with a 4.7 V8 engine. At idle, the difference to the stock muffler is not noticeable, but you can hear it when you step on the gas. There are no drones at all on the HWY! I felt an increase in performance in terms of acceleration but not the V8 sound I was hoping for. Although it is very well made and looks cool. Bottom line: If you want V8 sound, pick 18, but you can get the thump on the HWY. 22 is a safe bet if you don't need a drone at all but still need performance.
