Invidia Racing Series Cat Back Exhaust 2002-2007 WRX / 2004-2007 STI
The Invidia WRX Exhaust System is constructed with fully polished SUS 304 stainless steel. The exhaust features CNC machined flanges, robot TIG welded, and computerized mandrel-bent tubing for the straightest possible line and the lease amount of bends. This pipe does not have a resonator in the exhaust making it the straightest least amount of turbulence possible. Also it gives a very aggressive race sound.
