Review on MagnaFlow Exhaust Products 12586 Muffler by Shane Sanchez

This muffler was installed on my 4th generation Toyota 4Runner V6 in addition to removing the factory resonator and redirecting the exhaust to the car behind the rear wheel. Quality as expected from Magnaflow - stainless steel body, solid welds and overall just a great looking muffler. The delivery was quick but the box was a bit wrinkled when it arrived. No big deal as the muffler itself didn't look damaged in any way. For those considering a 5x11x22 muffler for their 4.0 T4R I think this particular size is perfect. I originally installed the 18-inch model and the roar at highway speeds and under load was almost unbearable. This size is perfect in my opinion. It makes a hoarse growl under acceleration, but it doesn't honk or wake neighbors while idling around the neighborhood.
