Description
The MagnaFlow Street Series Performance Exhaust System (part number 19370) is a cat-back system made from 409 stainless steel. It has dual inlets, four outlets, and a split-rear exit, with natural-finish tubing and a 3.00-inch intermediate pipe and tailpipes.
Three included mufflers use a perforated-tube design with packing. Each is made from 409 stainless steel and has a polished finish. The kit also includes hardware and four round, slant-cut tips. The tips have 4.00-inch outlets, polished 304 stainless steel construction, and rolled, double-wall edges.
MagnaFlow describes its Street Series systems as using straight-through flow designs and mandrel-bent tubing, engineered to balance interior and exterior sound levels and tested against SAE J1169 standards. This system is sold as a kit and is not remanufactured.
