b. The bolts should face towards the outside of the car. Figure 11 shows the passenger’s side tip. The driver’s side tip should have the bolt end facing the opposite direction. -
The tips should be clocked where the middle of the first N is centered.
a. Line up the tips where the bumper is aligned to the tip edge.

Exhaust Adjustment
Small adjustments may be needed on the Inlet Tube in order to center the tips appropriately. The following is recommended.
- Push the tips up and towards the front of the car.
