Competition Headers for Supercharged 3.8L V6 L67

The Pacemaker PH5061 competition headers are engineered to enhance the performance of Supercharged Ecotec 3.8L V6 (L67) engines specifically in automatic transmission Commodore VT, VX, VU, VY, Monaro V2, and Statesman WH, WK vehicles. All units are jig welded for guaranteed fitment and undergo rigorous checks before shipment. Featuring a tuned design, the primary pipes measure 1 3/4" (44 MM) and the outlet is 2 1/2" (63 MM). These headers are equipped to accommodate power steering, air conditioning, and oxygen sensors. Pacemaker utilizes their proprietary Pipe Over Cone™ technology, which ensures no protruding pipe inside the collector cone. This design increases exhaust gas flow, reduces turbulence within the header, and ultimately results in better gas flow and increased horsepower. The headers have a heat-proof finish tested to 1270°. Installation is estimated to take approximately 2 hours. It is important to note that these headers will not fit VS models. Comprehensive fitting instructions are included with V8 sets, along with hi-tensile header bolts.
