AussieSpeed offer some of the best Slant Six 170,198 & 225 performance & dress up parts available today. In our extensive research we found that header / extractor exhaust manifolds were limited for supercharged engines. AussieSpeed now offer Australian made cone over collector mandrel bent extractors using CNC benders for accurate kink free bends every time. These pipes fit both left & right hand drive Chryslers. Our Testing found that the 1 5/8 AS0198 extractors performed better on supercharged Slant 6 engines & there is a noticeable loss in bottom end power in non supercharged slant sixes.
