I dont understand why these people with CFI cars spend good money on extractors before they do the MPI conversion!
The MPI converson is cheeper and more effective in getting more power from your car. Extractors will get you 10kw if u r lucky where the MPI conversion will give ya 20kw for 1/2 the cost! If you just want a beefy sound, cut off a muffler and do the MPI conversion!

Then save a bit more cash for a good zorst and Air intake! :s6:
