I have made this Howto, regarding the 3 pipe mod, and hope its ok 🙂

Step1:
Remove the plastic pipe from air box.
Step 2:
The long tube that goes into the air box, cut it to only enter an inch.
Step 3:
The 1st resonator pipe is located under the drivers headlight behind the wheel splash guard:
Use a Junior hacksaw, cut the end of this pipe off at a 90degree opening it up.
Step 4:
The 2nd resonator pipe, is to be found along the front panel of the car and requires access from beneath. Locate the pipe and remove it completely. As with the 1st resonator pipe, cut the blank end off and then refit.
