They are constructed from 100% 304 grade stainless steel with mandrel bent 3\" piping, TIG welded in house and built in the USA. The factory turbine housing uses a 3.5\" V-band flange, which Evolution Racewerks duplicated and CNC machined from billet 304 stainless steel, and the O2 sensor bungs and laser cut brackets are TIG welded with stainless rod. The O2 sensors stay in the factory locations and the factory donut flange design is retained, so the set is fully bolt on.\u003c\/p\u003e\n\u003cp\u003eExhaust restriction costs horsepower and torque on a turbocharged engine, and the factory catalytic converter is the biggest offender. Its honeycomb catalyst forces exhaust gas through a fine weave and creates turbulence downstream that slows flow further. Replacing the factory catalyzed downpipes with the Competition Series catless units raises the peak power curve, brings torque in earlier and holds it longer, and sharpens throttle response and turbo spool.\u003c\/p\u003e\n\u003cp\u003eThe downpipes are designed to fit the factory exhaust or an aftermarket system with no compatibility issues.

ER uses a 200 cell metallic core, so each cell is larger and gas passes through more easily. Lower cell count equals higher flow, and higher flow means more power, less turbo lag and better throttle response. A metallic core also tolerates higher temperatures, lasts longer and weighs less than the factory ceramic unit.\u003c\/p\u003e\n\u003cp\u003eConstruction is 100% 304 grade stainless steel with mandrel bent piping, 100% TIG welded by ER's in-house fabricators and built in the USA.
