The sound is amazing once up to 3000 rpms. The only trouble was installation on my 2.5l because injen does not address the problem of the ecu and power steering directly in the way. I sent them pictures and they said my car was different than all the others (which it's not). I had to move my power steering and ecu and was able to make it work. Definelty worth it, I love it.
