Description Installation Guide FAQ Shipping & Returns

This Catless Subaru GT35/GT35R downpipe replaces the restrictive factory downpipes and removes the catalytic converter for maximum flow. Engineered for Subaru, it’s a direct bolt-on upgrade that delivers stronger mid-range torque, faster turbo spool, and a more aggressive exhaust note.

Who This Is For

Subaru owners running an aftermarket GT35 or GT35R turbocharger who want a 3" high-flow downpipe that bolts directly to the turbocharger outlet.

Key Features

  • 3" diameter for unrestricted exhaust flow
  • 16-gauge T-304 stainless steel with computerized mandrel bends
  • TIG-welded joints for heat-cycle durability
  • CNC machine flange for maximum strength and durability
  • Chrome-plated flanges for corrosion resistance
