DIY - Exhaust flap mod (Golf Tee)

First of all let me thank 1.fresh.f30.335 for providing some directions oh how to do this.

Step 1:

Get tools together; flat head screw driver and wire.

I bought this for like $4 because i couldn't find any wire and this came with wire.

Step 2:

Look at the spring that we need to remove.

Step 3:

Get flat head screw driver and place between spring and exhaust. Now twist and spring should fly depending on how big your screw driver is.

Step 4:

attack from other angle to repeat the above step for the end of spring which is attached to motor.

Step 5:

After Spring is removed twist the knob spring was attached to on exhaust side to open flap.

look down tailpipe with flashlight to verify.

Step 6:

run wire through the grove and tie around exhaust.

I also used some of the exhaust bandage from that package I bought to cover some of that wire.
