I have a 2010 Dodge Ram R/T which didn't sound to bad on its own, but after putting this CAI on, man what a difference. It sounds awesome. It has a very deep tone when you get on it, almost like having true dual exhaust.I haven't had a chance to see if the fuel milage is any better, but that really isn't what I bought it for, I got it in hopes of making my truck sound as powerful as it looks and I was'nt disapointed. I also put true dual exhaust on with flowmasters and with the CAI I just can't say enough good things about it. This is an excellent product and I would recommend it to anyone that wants to make there vehicle sound awesome.
