aFe Power Twisted Steel Long Tube Header 02-21 Subaru Impreza WRX/STI/Legacy (Unequal Length)

This aFe Power Twisted Steel Long Tube Header replaces the factory exhaust manifold on 2002-2021 Subaru Impreza WRX STI and Legacy models with 2.0L or 2.5L turbo engines. Mandrel-bent 304 stainless steel tubing delivers smoother exhaust flow for added horsepower and torque gains. The unequal length design produces the signature Subaru WRX rumble while ensuring direct bolt-on fitment with no modifications to the factory exhaust.

Key Features

  • 304 Stainless Steel Construction: Brushed finish 1-5/8 inch to 2-1/2 inch mandrel-bent tubing resists corrosion and withstands high heat for long-lasting performance
  • Optimized Tube Lengths: Engineered unequal length runners improve exhaust scavenging and volumetric efficiency across the powerband
  • Laser Cut Flanges: Precision flanges create a tight leak-free seal to maintain backpressure and prevent exhaust leaks
  • 100% TIG-Welded: Full penetration welds provide maximum strength to handle boost pressure and track abuse
  • Bolt-On Compatibility: Down swept tube direction aligns perfectly with factory catalytic converter and cat-back system

Product Notes

  • Unequal length configuration retains the distinctive Subaru boxer rumble note
  • Rectangle port shape matches OEM manifold for seamless transition
  • Oversized item requires freight carrier for delivery

Installation Notes

  • Professional installation recommended.
  • Bolt-on design reuses factory gaskets and studs with no cutting or welding required
  • Position collector outlet at 2.5 inch size to connect directly to stock downpipe
