Project Green Speed


Work on our Green Speed mission has been ongoing behind the scenes for multiple years, and the product of that work is now coming to light.  We take the role of being good stewards of the environment as well as our customers’ safety seriously.  As we continue to put effort towards being a leader in the aftermarket industry by developing and delivering responsible hard parts, packages, and tuning solutions across all of our supported platforms, you are going to see some changes to calibration (OTS Maps) availability and upgrade path progression on some of our platforms.  This is a large undertaking and there will continue to be several ongoing initiatives, some of which we’ll share a bit about below.

California Air Resources Board Executive Orders (CARB EO) and Emission Status on Products and OTS Maps

As mentioned above, this is not a new initiative for us.  While the aftermarket industry has seen the need to adapt a bit more significantly in recent years, we received our first CARB Executive Order (EO) in 2009 covering our Subaru, Mitsubishi, Mazda, Nissan, and Infiniti intake systems.  Over the past 6-7 years, we’ve ramped up our efforts with testing, partnered with SEMA Garage, and have an increasingly high volume of applications in process for products and calibrations to be covered by a CARB EO.  To date, we’ve amassed nearly 30 CARB EOs covering numerous Accessports, Stage Power Packages, Calibrations, and bolt-on modifications.  

Emissions compliance will continue to be a very important component in the development of both new products and calibrations (OTS Maps).  We introduced an Emissions section to all Product and Map pages in January 2021.  The Emissions section of these pages highlights the Emissions status of that product or OTS Map for customers.  If an EO from CARB has been issued for a particular product or Map, we provide the EO number and provide an external link to that Executive Order (EO) right from the product tor Map page.  We also provide details if that particular product is in the Executive Order (EO) application process, still in Emissions testing, or does not require an Executive Order (EO).

California Shipping Restrictions / OTS Map Download Restrictions

On January 28th we began to restrict product and Power Package shipments to California addresses if the product or Power Package requires an Executive Order (EO), but we don’t yet have an issued Executive Order (EO).  Once an EO is issued for specific products or Power Packages, they are immediately updated in our system, and those products are then available to ship to a California address.  On March 1st we began to restrict California customers from downloading OTS Maps that require an Executive Order (EO) but we don’t yet have an issued Executive Order (EO).  Once an EO is issued for OTS Maps / Calibrations, they are immediately updated in our system, and those Maps are available for California customers to download from the website and added to applicable Accessport Firmware.

Accessports – Preloaded Maps, Firmware, What Maps are Available, and Where

On March 1st, in addition to California OTS Map website download restrictions, we made an update to OTS Maps that are preloaded into Accessport firmware.  If an Accessport does have an Executive Order (EO) issued for OTS Maps / Calibrations, we’ve removed all OTS Maps from those Accessports and firmware that do not yet have an issued Executive Order (EO).  Some additional OTS Maps (not preloaded on the Accessport) will continue to be available for download on our website.  In situations that an Off-The-Shelf Map is not currently available for your car’s configuration, our Protuner network is still available for custom tuning.

Migration to GESi Catted Downpipes and Related OTS Map Updates

One of the first modifications generally made to a turbocharged car is an upgraded downpipe.  For over a decade, COBB downpipes have been the status quo when it comes time to upgrade supported Subarus, Mazdas, Mitsubishis, Fords, and more.  Featuring quality stainless tubing and CAD-designed cast bellmouths, our downpipes are the best fitting and most proven on the market.  Over the past couple of years, we set out to make the best downpipes available even better.  Our most popular downpipes are receiving updates to improve overall fitment, ease installation, maximize durability, and the inclusion of our proprietary GESi cat.  While some versions have already received these updates, we are continuing to work towards transitioning all of our exhaust components (Downpipes, J-Pipes, etc.).

In March 2021, we’ve removed all OTS Maps from Accessports, Firmware, and our website that contained disabled DTCs and toggles.  These OTS Maps are no longer offered and are no longer available. We did release improved OTS Maps, and we have re-enabled all superfluous trouble codes including those related to catalytic converter efficiency. When used in conjunction with our new GESi catted downpipes and Stage Power Packages, users can expect DTC-free operation of their vehicle.  Some platforms and/or vehicles are waiting for inventory and an “official” release of our new GESi Downpipes or J-Pipes.  The improved OTS Maps associated with these releases will not be available until inventory is shipping to Dealers and Customers.  Click here for the full breakdown and a list of updated exhaust components. 


COBB will continue to lead the way with our Authorized Dealer Network partners, aftermarket industry manufacturers, and our incredibly loyal customer base.  We will continue developing and delivering responsible hard parts, packages, and tuning solutions across all of our supported existing and future enthusiast platforms.

  1. Is COBB going to find a way to retrofit their E85 sensor kit to use a different analog input or communicate over CAN? Or are all your customers screwed?

    • Hi Daniel, we are working on multiple avenues to bring Flex Fuel capability back to supported Subaru vehicles. It is possible that we will be able to offer a retrofit kit for those existing kits, but we will not be certain until we are further along in the development process.

  2. I am currently doing a 2005 Subaru STI swap into an Impreza RS and I am going to be using a Borg Warner Fullrace 7163 turbo kit will the access port be able to tune it as I am retaining all emissions equipment will running higher boost make the check engine light come on

  3. There is a lot of miss information out there and I have stumbled across a lot of it. I have a 2007 outback XT five speed that I was planning on buying a Cobb downpipe for and an access port. As long as it’s a catted downpipe and I have all of my emissions equipment installed and working will an aftermarket tuner be able to use the access port to install his tune on my car? I know I could just go with Cobbs off the shelf tune but this particular tuner is very good at mapping the AVCS and I just trust his tuning ability over the OTS.
    Thanks in advance for responding.

  4. So with your new software update and I am asking about Cobb downpipe. Does the Cobb downpipe have the correct catalyst material to not throw a code? I have a stock 2004 FXT

    • The COBB GESi Catted Downpipe available for your vehicle can be used without concern of causing a CEL due to catalyst efficiency. That said, we no longer offer an OTS file for that configuration so you would need to have the car custom tuned to safely account for the increase in airflow/performance.

  5. Hello! I was wondering if there will be an alternative to flex fuel, I am not sure if this is 100% correct, but I did hear you guys are working on an alternative that will be released this year, is that true?

  6. So I recently bought a completely stock ‘05 WRX. 1 owner, unmolested. I am looking to get a intake, down pipe with a cat and exhaust with a cat and an access port. Would a tuner still touch my car if I get those bolt ons with the cat? If not, I might as well sell the car.

    • Hi Roberto,

      You would likely get a CEL depending on what aftermarket downpipe you use. Everyone would still be able to tune it. You could make plenty of power on the stock downpipe though. I’d recommend getting with a tuner and seeing what they recommend.

  7. which parts are the ones that can be used and be able to make my car pass the emissions I have a 2017 wrx

  8. I have a COBB GESI Downpipe on my 2019 STI and it would throw a CEL every 25 or 30 miles so my tuner needed to use features that will not longer be available. I purchased this specific Downpipe to stay compliant, but apparently cannot. What is the recourse in this case?

  9. Really disappointing to see the reduction of support from Cobb here… I just struggle to comprehend how industrial and corporate greenhouse emissions run rampant, yet individual consumers continue to pay the price. Yeah, transportation as a whole is a large part of emissions, but geez, changing out an exhaust on a consumer car has such an insignificant impact overall. Just hate to see it… wishing Cobb the best, and hopefully more support from legislation in the future.
    I was looking forward to modifying my car yet again, and making it an individualized product that is unique and fun. Perhaps those days are over…

  10. That’s what happens when people vote for these green religious zealots. We no longer have separation of church and state… the church of Green must be bowed down to.
