Pacemaker are the
pioneers of quality headers
featuring the Mandrel bend
system. Pacemaker’s modern
workshop incorporates the
very latest equipment
available, including aircraft
quality computerised benders
with revolutionary, patented,
vertebrate type mandrel,
ensuring perfectly round
bends, previously unavailable
in Australia. Pacemaker are
the only Australian header
manufacturer to manufacture
their products with pipe over
the cone design. The
advantages are there is no
protruding inside the
collector cone, therefore
increasing exhaust gas flow
and eliminating turbulence
inside the exhaust header.
The result is better gas flow
and increased horsepower.

Additional features
include:

• Precision
  cut and machined thick
  flanges to eliminate leaking
  and warpage
• All
  headers are jig welded for
  guaranteed fitment and are
  checked prior to shipment
• Comprehensive fitting
  instructions with V8 sets,
  together with hi-tensile
  header bolts
• Emission
  hookups provided where
  applicable
• Primary
  pipes fitted through the
  flanges
• Heat proof
  finish tested to 1270°C
