Features & Product Details

Please note that this downpipe is for automatic transmission models only. If you're looking for a great way to add more power and torque to your turbocharged vehicle then an aftermarket downpipe is always a great choice. This is the Invidia Catted Downpipe that has been fabricated from 304 stainless steel materials, and when combined with smooth mandrel bends, larger 3" piping diameter, along with a large bellmouth, the results will speak for themselves. Expect more horsepower, more torque, along with improved throttle response and reduced turbo lag to make for an excellent modification. 

This downpipe will also bolt up to the stock cat-back exhaust system or stock replacement exhaust system. Additionally, it will also come with an extra O2 Sensor bung for those of you who need to install an aftermarket wideband O2 gauge. 

This is a 2-piece downpipe that will come provided with new gaskets, as well as new hardware to make it ready for the installation. 

Note that this downpipe only fits vehicles equipped with the manual transmission.

Tough install 11 months ago
Darth Subious
This thing fit perfectly. That being said two of the nuts on the turbo studs had to be torched off. We were able to save the studs but it took an Indy car wrencher on a Saturday with a car lift to do it. I got lucky. This was with an 18,000 mile car. Do yourself a favor. Spend the money on new studs when you buy the gasket and nuts. Replace all of it. When I upgraydde the header I'm going to on principle.

QUESTIONS & ANSWERS

  • Q: Tune  Mattyboi5622 years ago

    Do you need a tune if you put this on with the invidia n1 race ?
  • Q: Catted or Catless?  WRX153 years ago

    In the description it says, "this catless downpipe is for off-road use only." So is this a catless downpipe? Or just a typo in the description?
  • Q: 2 parts looking the same  Lewdsquirrel3 years ago

    Hi, For my WRX 2016 I can see 2 Invidia downpipes almost identical, same description, with the same price but a different part number, INV HS15SWMDOC and INV HS15SWADOC, could you tell me the difference? Which one should I use with the Invidia catback INV HS15STIG3S to get a full turbo back exhaust? Should I also get any extra gasket if ordering the complete Invidia turboback kit or does it comme with "eveything" I need to install it? Thanks.

      A:  HS15SWMDOC is for the 6 speed manual transmission HS15SWADOC is for the CVT transmission. This includes all gaskets besides the turbo to downpipe gasket.
