Description
Make sure that for any pipes that require
bending, the radius of the bend is
minimum 2.5 x tube diameter.
Make sure that sufficient clearance is
maintained for all driving conditions to
all hot and moving components.
NOTE: Where possible all pipe connections
should be designed so that the gas flows from
smaller to larger diameter pipes.

Exhaust Heat Shields
• Catalytic converters, in particular, operate at
high temperatures.
• Ensure existing shields are maintained.
• Add further shields over exhaust system as
necessary to avoid fire risk.
