  • Q: COBB down pipe installation   Mtb377 8 months ago

    I have a cutback 3 inch Magnaflow exhaust on my 05 sti and I was wondering what type of gasket or adapter I need to install a COBB down pipe?
    • 0 of 0 people found the following answer helpful

      A:  You'll want to do an OEM style downpipe to 3 inch catback adapter like this for the best fitment: https://www.rallysportdirect.com/part/exhaust-gaskets-and-hardware/grm-077046-grimmspeed-oem-downpipe-to-3in-cat-back-adapter

  • Q: Questions with this on an 07 WRX  Adam B.8 months ago

    I'm currently running a stock downpipe on my 07 WRX to an Invidia N1 3", with a proper OEM downpipe to 3" catback adapter so there's no leaks. I plan on buying this downpipe from you guys very soon, what will I need in addition to make this fit with my setup (gaskets/adapters/etc.)? It seems like from one of the previous questions answered, I'll need to retain use of the OEM downpipe to 3" catback adapter with this COBB pipe. Is this really the case? (Seems odd to me, as I'd assume a 3" downpipe wouldn't need an adapter to mount to a 3" exhaust)
    • 0 of 0 people found the following answer helpful

      A:  You would want to use the same adapter as the OEM downpipe, since the Cobb Downpipe retains the OEM style flange instead of the traditional 2 bolt 3" flange that most aftermarket downpipes use.

    Will this match up with my invidia n1 catback exhaust?

      A:  Yes, this will fit on an N1. We do recommend you install with the OEM downpipe to 3in cat back adapter to avoid any exhaust leaks.

  • Q: tomei expreme ti mating up?  RELprojects1 year ago

    I recently bought the tomei ti extreme catback exhaust, wondering if this cobb will match up because on the picture shows the flange isn't flat and has that donut gasket pipe at the very end. As for the tomei flange is flat. would it match up or will that cobb pipe flange get in the way?
    • 0 of 0 people found the following answer helpful

      A:  For the best fit between a 3 inch flat flange like the Tomei and a donut flange like the Cobb an adapter is recommended. An adapted rlike the Grimmspeed GRM 077046 works well for this connection.

  • Q: Cobb tuning downpipe  MarioHdz26261 year ago

    Do l have to reflash my ecu after installing the downpipe? Is it safe to run the car without it till l get the cobb accessport?
    • 1 of 1 people found the following answer helpful

      A:  Tuning will be required when changing out the downpipe. We would recommend installing the Accessport at the same time as the downpipe.

  • Q: DP  JonathanStone1 1 year ago

    Will this item fit on the stock turbo back and onto a perrin cat back exhaust on a 04 wrx wagon?
  • Q: Fitment  Drift.One2 years ago

    I was looking into this downpipe and wanted to know will this bolt up to the ETS cat back exhaust?
    • 0 of 0 people found the following answer helpful

      A:  The ETS catback might have a 3" connection and would require an adapter since the Cobb downpipe has a 2.5" catback connection.

  • Q: Tuning required?  Elusyve3 years ago

    Hi, I'm looking to replace my stock Cats with this downpipe and mate it with the stock exhaust system. Everything on my 07 STi is stock. I do have a couple of concerns: 1) Do I need a different turbo to DP gasket other than a stock one? 2) Will This throw a CEL even though it is Catted? 3) Will this come with the gasket needed to mate with the rest of my stock exhaust piping? If not, will the factory ones work fine? Thanks!
    • 0 of 0 people found the following answer helpful

      A:  You will need a new turbo to down pipe gasket. A Cobb Accessport is strongly recommended, as you will need an OTS map from Cobb. And this down pipe has a 2.5 inch flange and will mate correctly to the OEM exhaust. It is recommended to replace the OEM donut gasket as well.

  • Q: check engine light?  n33d4sp33d133 years ago

    Firstly I'm currently using my stock downpipe with a cat back exhaust and stage 1 tune. will replacing my stock downpipe with this cause my cel to come on? Does this have a place for both 02 sensors to connect?
    • 0 of 0 people found the following answer helpful

      A:  As long as you are using COBB's Stage 2 tune this will not throw a CEL. This has two O2 sensor bungs, but the factory setup only uses one for the downpipe, the additional is for an aftermarket wideband if you need.

  • Q: Twin scroll turbo  johnstonb933 years ago

    Will this Downpipe work with the bloush twin scroll turbo that uses stock location? I know I will also need to purchase special headers for this turbo too. Blouch Dominator 1.5XT-R 10cm^2 Twin Scroll JDM Turbo Subaru Models (inc. 2002-2007 WRX / 2004-2015 STI) Tomei Expreme Twin Scroll Exhaust Manifold Large Piping JDM Subaru STI 2003-2014
    • 0 of 0 people found the following answer helpful

      A:  Twin scroll turbochargers use a different exhaust housing flange and this will not fit. You will need to source a specialty twin scroll downpipe which we do not supply at this time.

  • Q: 06 tr  TWB16163 years ago

    Since the 06 downpipe is a little different than the others because it's longer, I wanted to make sure that this downpipe will fit. So will it?
    • 0 of 0 people found the following answer helpful

      A:  All 02-07 downpipes will be the same length and this is confirmed to fit your 2006 WRX.

  • Q: Fitment/tune  JBPwagon013 years ago

    2004 WRX - I currently run stage 1 on a V3 AP, cobb SF intake, and magnaflow catback exhaust. Will this DP bolt up to my catback, and what kind of power can I expect to gain after installation/running stage 2 on the AP? Thanks!
    • 0 of 0 people found the following answer helpful

      A:  This downpipe will bolt up to a Magnaflow catback and you can expect approximately 20hp and 28 ft lbs more than Stage 1.

  • Q: Gaskets?  iamnotemonster771613 years ago

    What gaskets would you recommend purchasing with this to bolt up to my Cobb catback?
  • Q: What's the difference?  3 years ago

    What is the difference between this downpipe and the other one listed on this site part #COB 512202. Anything other than the cosmetic finish of the metal?
    • 0 of 0 people found the following answer helpful

      A:  512202 uses COBB's old logo, this unit has COBB's new logo. There is no performance difference between the two. The coloring in the metal is just color discrepancies in lighting from the photos.

  • Q: AP stage 2 requirements?  MattSax07WRXTR3 years ago

    Can I add this onto the stock exhaust on my 2007 WRX TR and run the stage 2 Cobb map? I like the sleeper sound and want the minimum upgrade to run the AP stage 2 map.
    • 1 of 1 people found the following answer helpful

      A:  COBB's downpipes do have the benefit of bolting directly to a stock catback without issues and the Stage 2 map can be run in this setup. A turboback will see a bit more power, but running just a downpipe on those maps is very common.
