Product Details

The Injen SES1205DP is a 3-inch (76mm) high-performance downpipe with an integrated high-flow catalytic converter, engineered as a direct replacement for the restrictive factory downpipe on turbocharged Subaru WRX and WRX STI models. Designed and manufactured in Pomona, CA, this downpipe delivers dyno-proven gains of up to 24 hp and 12 lb-ft of torque over the stock unit.

Injen engineered this downpipe around a divorced wastegate discharge design, which separates wastegate flow from primary exhaust flow to reduce turbulence and maximize exhaust velocity through the turbo. The entire pipe is constructed from premium 304 stainless steel mandrel-bent tubing for smooth, unrestricted exhaust flow and long-term corrosion resistance. The turbo bellows section is a CAD-designed, 304 stainless steel investment cast piece that includes the upper O2 sensor bung for a complete, plug-and-play installation.

Key Features:

  • Dyno-proven gains of up to 24 hp and 12 lb-ft of torque
  • Full 76mm (3") piping made from premium 304 stainless steel mandrel-bent tubing
  • Included high-flow catalytic converter for street-friendly performance
  • Divorced-style turbo bellows design reduces turbulence and improves flow efficiency
  • CAD-designed 304 stainless steel investment cast turbo bellows with upper O2 sensor bung
  • Hand TIG-welded construction for race-proven strength and resistance to heat cycle cracking
  • In-house dyno tested for verified performance results
  • Designed and manufactured in Pomona, CA

Also Available: For a race-only downpipe without a catalytic converter, see Injen part number SES1204DP. For a complete exhaust system, pair with the Injen SES1206TT 3" to dual 60mm cat-back exhaust.

Note: Does not fit 2015+ WRX (base) models — STI fitment only for 2015 and newer. This part is not CARB exempt and is not legal for sale in California or use on California-registered vehicles. Off-road use only.

⚠ WARNING: This product can expose you to chemicals including Chromium, Nickel, and Cobalt, which are known to the State of California to cause cancer. For more information, visit www.P65Warnings.ca.gov.

The order was shipped promptly, and everyone was is good working condition. I will order from here again!!

Wish Canada or Amazon.ca carried these anchors. Maybe you could look into that. A follow-up would be appreciated since the information does not show the weight of your item, hoping it is only 4 pounds for us old goats :)

I am pleased with Autoplicity. There was a miscommunication on shipment, but after a phone call, everything was handled. Looking forward to my parts coming in. Thanks guys!

I purchased an Optima Red Top 75 battery from Autoplicity and they have some of the best prices available. The item was shipped right away and they knew the inventory that was available, not like others who said there may be a 2 to 3 week shipping time frame. So far the service has been great and I look forward to continued great service.

Fast and inexpensive. Thanks.
