Features & Product Details

RallySport Direct is proud to provide you with a large catalog of quality automotive performance and cooling products brought to you by Mishimoto. 

 

Here, you are looking at the Mishimoto Catted Downpipe. This is a nice upgrade that replaces your factory pipe that is heavy and restrictive, and the Mishimoto unit has been designed with smoother bends and a larger piping diameter. The result is more horsepower and more torque, along with improved engine response. 

 

 

 

DETAILS:

  • Direct fitment
  • Dyno-proven gains of up to 57 WHP and 52 WTQ with the catted downpipe and a tune, using 93 octane fuel on a 6-speed (for example other fuel and elevation factors will differ)
  • Dyno-proven gains of up to 73 WHP and 64 WTQ with the catted downpipe, a tune, and the Mishimoto Performance Air Intake 93 octane fuel on a 6-speed (for example other fuel and elevation factors will differ)
  • Significant torque improvement in the low end and across the entire power-band
  • Fits with both CVT and manual transmissions
  • Extremely aggressive turbo and exhaust flow under acceleration and boost
  • 304 stainless steel one-piece design allows for uninterrupted exhaust flow
  • 3/8" thick stainless steel, CNC-machined four-bolt flange
  • 3.5" to 3.0" transition out of turbo outlet allows exhaust gas to flow smoothly
  • Additional wideband oxygen-sensor bung plug-in ideal location for aftermarket wideband sensors
  • Mates with the stock cat-back exhaust
  • New studs for turbine housing
  • Includes stock gasket for turbo outlet

    It’s like everyone else was saying, the turbo studs were a pain to remove but got em all off. You’ll wanna keep that penetrating lubricant handy too. Sounds amazing!! I paired it with an Invidia N1 CBE, it’s even louder!!! I also got a Cobb AP and currently running a Stage 2 OTS tune. Next up? Air intake. Idk if I should get Mishimoto or Cobb SF. We will see once this quarantine is over.

    The stock downpipe is incredibly restrictive, and this downpipe really woke up the WRX. Along with a tune it was a night and day difference in power. The install can be a bit of a pain, but this is no fault of the Downpipe.

    QUESTIONS & ANSWERS

    • Q: Invidia r400  Subaustin 1 year ago

      Will I need anything extra to be able to put this with the Invidia Gemini r400 catback exhaust?
    • Q: Fitment   Jacob 2 years ago

      Will this fit my magna flow competition exhaust?
      • 0 of 0 people found the following answer helpful

        A:  The Magnaflow Competition catback tapers down to a 2.5" stock style flange, you will want a 3" downpipe to OEM catback adapter for proper fitment.

    • Q: OEM Exhaust  Larry 5 years ago

      Will this fit in an OEM exhaust ?
      • 0 of 0 people found the following answer helpful

        A:  Due to this being 3" at the flange and the stock exhaust being 2.5" it would not be a perfect seal between the two flanges and the 3" Downpipe to OEM Catback Exhaust would be highly recommended.
