Motordyne Engineering Long Tube Headers - 370z
 
Combining performance and versatility, the 370Z Long Tube XYZ Headers (LT-XYZ) are made of polished stainless steel 304L alloy with back purged and TIG welded construction.  A stepped header design optimizing HP/TQ while being biased more toward HP.  1-5/8″ primaries stepped to 1.75″ to the 2.5″ merge collector. The LTXYZ exhaust header allows interchangeable modules for application, versatility and customization. Easy to adapt  for different sounds, experimental applications, sonic cut out, reduced emissions or maximum performance.
The V-band clamp makes changing modules easy.
