Overall I like this exhaust. There is a drone on my truck at 65 under normal use and a bit excessive when I'm pulling my 22' travel trailer. Over time I am getting use to it. My MPG hasn't reduced, it stayed the same. However, I did also install the AFE Magnum Force Air Intake. I was hoping for a little more torque from this setup but overall a great product for the price.

Arrive in great condition. Installed in just 45mins. The muffler sounds really good in idle and when shifting gears but starts drone at 65-80mph. I tweak and ended up cutting the tailpipe after the muffler hanger with exhaust pointing at 45 degree angle before the differential. The drone decreased about 75%. I havent seen any improvements on the mpg but on the torque its quicker than the stock. They will hear you once you stomp your foot in the gas. Gibson has a deep sounding tone

I installed the gibson exhaust on a 2010 toyota tundra crew max with the 5.7 v8. It has an excellent deep sound, and instantly gave me more power and added about 3.5mpg. not bad for just an exhaust, I highly recommend it!
