i installed the k&n cold air intake, was very easy to do. it also looks great under the hood. in addition i also had a magnaflow s.s. exaust put on and it has just enough rumble to sound good. i would recamend this setup to anyone. FYI
sorry just now getting this, just went to the muffler shop and told him i wanted something with a little rumble. it is a single in, single out s.s. in the same place as the stock unit.
