Two Step Performance High Efficiency Downpipe for Honda 2.0T
A downpipe upgrade is one of the most effective modifications for increasing efficiency on Honda’s 2.0L turbo engine. The Two Step Performance High Efficiency Downpipe promotes optimal airflow with virtually no turbulence throughout the body of the downpipe.
The design uses 304 stainless steel investment cast ends, CNC pocketed for a smooth transition to a 5.00″ OD, 400 CPSI GESI G-Sport catalytic converter. This catalytic converter was formulated for small displacement direct injection vehicles and offers optimal exhaust flow. It is EPA compliant and rated for use up to 1,000 HP. All components are fully back-purged on site to withstand high exhaust gas temperatures.
The wide shape of the cast inlet smoothly blends the turbine outlet and wastegate gases to reduce restriction, while the cast outlet tapers smoothly to connect with aftermarket or factory front pipes. No adapter is necessary. No ECU calibration or tune is required, and use of this downpipe will not result in a check engine light.
Four finish options are available: Raw (no ceramic coating), Silver Cerakote, Black Cerakote, and Bronze Cerakote. An optional 7-piece titanium exhaust stud kit can be added at checkout, covering the turbo-to-downpipe connection (4 studs) and the downpipe-to-frontpipe connection (3 studs). Stud kits are available in Raw or Burnt finish. All kits include gaskets, stainless hardware, and components needed for installation. This product cannot be shipped to California.
