Depends on what you consider to be a benefit. You "might" see "some" improvement in fuel economy, but don't take that to the bank. Exhaust note (sound) is certainly going to change, and to some that would be a benefit, to others it would not.
I,m looking to add hp and mpg cheaply. I put a k&n filter in my factory airbox already and would like to mod the exhaust without killing the bank. Can't be too loud as I have kids that need to sleep long hauls.
