Go with Magnaflow. My 4runner sounds nice, my Cressida sounds really nice.
Seems like Magnaflow is 6cylinder friendly vs the others lol.
Heres the Cressida exhaust with 1 factory cat, 1 Magnaflow cat, 2.25 inch pipe from the cat to the back, then a Magnaflow muffler 2.25 inlet, 2.25 outlet with chrome 3" x 10" chrome tip. BTW, the deeper, wider the tip, the more deeper sound. Learned that the expensive way.
