Pacemaker 5270
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
