Flowmaster American Thunder Sounds Great!
I just installed the American Thunder Dual Exhaust on my 2016 Toyota Tacoma 4x4 TRD Sport and I like it! Sounds great! Looks great! I really love the throaty sound when I fire it up. All in all, I'm really glad I decided on Flowmaster, and that I purchased it.
Overall I'm very happy with the headers, appearance, construction, performance, and installation. Some recommendations would be: 1-Driver side header collector flange weld needs to be ground to allow washer to sit flat on flange. 2-Hardware: would suggest flange nuts/bolts instead of provided hardware or more/larger flat washers to prevent bolt heads from being pulled into flange mounting hole.
