Downpipes

Unlock your turbocharged engine's potential with a high-performance downpipe. The factory downpipe is often the most restrictive section of the exhaust system, featuring sharp bends, narrow diameters, and dense catalytic converters. Replacing it with a free-flowing aftermarket downpipe reduces exhaust backpressure, allowing the turbo to spool faster and increasing horsepower and torque.

When selecting a downpipe, consider these key factors:

  • Diameter: Common sizes include 2.5", 3", and 3.5". Larger diameters support higher horsepower but may affect exhaust gas velocity at lower RPMs.
  • Material: 304 stainless steel offers durability and corrosion resistance, ideal for performance applications.
  • Catalytic Converter: Choose between catted downpipes (retain some emissions compliance) and catless (maximum flow, off-road use only).
  • Fitment: Downpipes are vehicle-specific. Ensure compatibility with your turbocharger housing and exhaust routing.
  • O2 Sensor Bungs: Verify that the downpipe includes properly positioned bungs to avoid check engine lights and allow tuning.

Whether you're chasing lap times or building a high-powered street machine, our collection offers downpipes from trusted manufacturers to help you achieve your goals.
