Wheel width: 305 - 355mm.
Minimum ride height: 80mm.
Minimum start of the last 100mm of exhaust: 200mm above the reference plane.
Minimum upward angle 10°.
Closest positioning of the *rear* of the tail pipe to the rear wheel centre line: 500mm.
Here's a diagram of all of that, assuming you do
everything you can to manage to point the exhaust at the break duct. This is all to scale.
