Heres a short video of what this intake sounds like,as I'm getting on it down the highway.
Eventually I'm going to have a custom exhaust fabbed up,but for the time being to give the E some sound,I removed the large factory muffler and had a straight pipe welded in.If your not familar with the factory setup,it has a some what large straight through resonator behind the factory catalytic convertor.So since the resonator is fairly close to the cat,and the exhaust pipe that remains is quite long,it actually cancels out that annoying high pitch exhaust sound,that many imports seem to emit.
