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.
- 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
