The Wait is Over for the 2021+ Mazda Turbo Downpipe

Fits Models Mazda 3, CX-30, CX-50

Unleash the potential and growl from your car and take the step forward into more power! A full 80mm Turbo Back exhaust is now possible with CorkSport’s new Catted Turbo Downpipe for the 2021+ 4th Gen Mazda3 Turbo (as well as CX30 & CX50 Turbo Models)!

Best Mazda Catted Downpipe Kit from CorkSport

Our downpipe uses a two-piece design, making installation easy without the need to wrestle with a single large, cumbersome pipe. The Downpipe starts with a high-flowing cast 304 Stainless Steel Bellmouth, then joins the 80mm mandrel-bent piping with a V-band connection for a leak-free seal.

We used 3D scan data from the OEM downpipe when designing our CS pipe, which means fitment is just like OEM and the CorkSport Downpipe will fit with any aftermarket Cat-back exhaust system, or even OEM!

Best Mazda 80mm Downpipe

A high-flow 300 cell Catalytic Convertor is utilized in our downpipe and has been tested to have no significant effect on power potential.  A catless option is not available.

Do I Need A Tune?

Addressing the other elephant in the room: Tuning. We highly recommend getting a tune after installing the 80mm downpipe as there are very strict airflow limits in the stock tune that severely limit power. This will result in some mild stutters, surging, or “hiccups” at wide-open throttle. This does not do any damage as it is simply a very conservative safety limit for stock components.

With more flow-efficient parts (i.e upgraded intakes , Turbo Inlet Pipe, and exhaust systems), these limits are being reached much easier and the ECU will limit the power output of the engine. The vehicle will be drivable on the stock tune and still give you an aggressive growl out of your 2.5T!  

Here you can see the power gains with a fully-bolted Mazda 3 Turbo that is tuned vs stock downpipe and stock tuning.

It’s Go Time with The Mazda 6 Turbo Kit

Do you ever find yourself in a situation where you could have used another +100hp? As in, getting on the freeway safely or trying to beat that minivan at the red light so you don’t miss your next turn? Maybe you know a guy with a WRX with a muffler delete, and he just won’t shut up about how “fast” it is. Well, let me tell you, my 2016 Mazda6 GT will do all of that in comfort and style! I’ve been lucky to be the first person in the world to run CorkSport’s Turbo Kit on a Mazda6, which also happens to be an automatic! #ridetheunicorn

I bought the car in early May 2022, and by the 31st, the CorkSport engineers had transformed my naturally aspirated Mazda into something special with the CS Turbo Kit. Flash forward a little less than a week out, and I was on my way to @Idaho Mazda Takeover to show off the kit. It’s a 450-mile trip one-way from my house to Caldwell, ID, and does not include the +300 miles of community shenanigans I completed while I was there. 

* This is Mazda 3 Manual Dynograph, with 80mm Cat Back Exhaust

As a testament to the CorkSport Mazda 6 Turbo Kit, I made the journey without a second thought. I averaged ~75 mph and snagged over 32mpg on the way there. This included spirited driving, stretching the car’s legs, and putting it through its paces, up, over, and through those difficult passes in eastern Oregon. I need you to understand this was a 100% stock Mazda6. The only thing we did was install our turnkey kit. In less than a week, I put over 1200 miles of “FUN!” on the car and have not looked back!

The CorkSport Mazda 6 Turbo Kit

The car drives as it did right off the dealership parking lot; it’s quiet and very tame, with a stock catback. You lightly press the throttle, and the car’s cab starts to fill with all the right induction noises. Hearing that turbo spool up for the first time sent chills down my arms; I couldn’t believe it. My Big turbo Mazdaspeed3 isn’t even that seductive. But that’s only part of the fun…

When you drop the hammer, the auto transmission immediately puts in the work. I was surprised at how quickly it locked up the torque converter and rocketed the car down the road the first time I drove it. I was worried about the implications of having ~80 additional whp rifling through it. After a few deep dives into how these transmissions work, I feel more confident than ever about the Mazda 6 and Turbo Kit, and the last 10K miles of beta testing have been trouble-free.

* This is Mazda 3 Manual Dynograph

I’d never driven a boosted automatic before, let alone an aftermarket one, so I didn’t know what to expect. What I’ve experienced has been more than I could bargain for. By design (of the OTS Professional Tune), you only use the boost when needed; otherwise, the car will drive like it’s not there if you want to go that route. However, if you mash the pedal to the floor, it’s “Go time!”

Since installing the turbo kit, I’ve supplemented this turbo kit with our 2014-2017 Mazda6 Catback. The stainless T-304 has enhanced this whole experience. The 90mm tips look great with those shiny resonators behind the rear bumper. It is starting to dial back on the sleeper, sleek and numb daily, and gearing more towards a fun, fast and capable 4-door sedan. The exhaust added around another 30whp and has me sitting comfortably near 260whp to the front wheels.

Undercarriage with Cat Back Exhaust

It didn’t take long for the numbness of the stock mounts to get to me. With this big bump in power, I wanted to do everything I could to help this car out. I installed the CorkSport transmission and rear motor mount, further evolving the turbo Mazda 6. Power delivery is now immediate and linear vs. the OEM mounts allowing the engine to bounce around.

A lot of us have very similar ambitions for our cars. We tend to create this inseparable bond between ourselves and the machine we’re driving. Having an OTS turnkey turbo kit that does precisely that is nothing short of spectacular. CorkSport has done an outstanding job offering a turbo kit that includes EVERYTHING you need, including a professional tune, battery, boost gauge, and boost controller. Heck, you even get Unicorn swag too!

Mazda 6 Turbo Kit Manifold

I’ve created a new sense of ownership by taking this project on; it’s changed my view on what I wanted from a car. This kit checks all the boxes in my book and has surprised me almost daily. My whole experience with the Skyactiv-G + CorkSport Turbo Kit has been rewarding. I cannot wait to push this car to its limits and beyond to see what these engines are truly capable of. 

If you have a 2.5L naturally aspirated 3rd Generation Mazda 3 or Mazda 6 sporting a manual or automatic transmission and want to get the most out of your ride – don’t hesitate to grab one of these turbo kits – the results are unthinkable!

New Product – Mazda 3 Hatchback Rear Spoiler 2019+

Enjoying your 4th GEN Mazda 3 but wanting to change up the look? Introducing the CorkSport Performance Spoiler for 2019+ Mazda 3 Hatchback. We went for an OEM+ design that incorporates the great fitment and lines of the OEM aero kit spoiler but in a much more aggressive package. Taller, longer, and with an upturned rear edge, the CS spoiler add some much needed sportiness to the look of your 3. Available in multiple finishes to suit your budget and build, the CS spoiler is a great next mod for your build! Read on for more details and check out the product listing here to purchase.

2019 Mazda 3 Carbon Fiber hatch wing

We like the OEM spoiler but were disappointed at how insignificant it looks when installed, especially when paired with the fairly aggressive OEM front lip & rest of the aero kit. The CorkSport Spoiler takes design cues from the OEM aero kit spoiler however, the design is unique to CorkSport. We started from scratch and polled the community for design opinions before settling on a final design that is both higher off of the rear hatch than OEM and extends further rearward than OEM. The design is finished off with an upturned rear edge for a great “duckbill” style look which is aggressive without being too much. You’ll be turning heads, especially when paired with CorkSport Lowering Springs and a nice set of wheels!

Forged Carbon Mazda 3 hatch wing

Fitment was equally important as aesthetics when we designed the CS spoiler. We 3D scanned an OEM aero kit wing to get the exact mounting surfaces and edge profiles so that the CS version fits just as good as OEM. We use the same mounting locations as OEM as well. This means no drilling if you’re switching from OEM aero kit to CorkSport spoiler. If you do not have the OEM spoiler you do have to do some drilling, however, Mazda pre-marks the holes for a relatively easy install! By using the same mounting locations and more adhesive mounting tape than OEM, you can be sure your CorkSport spoiler won’t be going anywhere!

2021 Mazda 3 Turbo Duckbill spoiler

The CorkSport Mazda 3 spoiler is offered in three finishes so you can choose what is best for your build. Each option uses a fiberglass base with different top layers. Regular woven carbon fiber, forged carbon fiber, and basic black fiberglass are each available. The carbon fiber options feature a UV resistant epoxy top coat for great protection from the elements and a mirror like finish. The full fiberglass option comes in a satin black coat with some light scratches and will require some finishing. We recommend some finish sanding and a final layer of paint or wrap. The shape is the same for each unit however the purchase price varies so you can really choose the best option for your build & budget.

3 options of Mazda 3 rear wing finish

Finally, each CorkSport spoiler comes with all the hardware and accessories needed for installation. This includes mounting bolts, washers, mounting tape, and rubber washers for waterproofing. We even include new replacement OEM Mazda clips that almost always break with removing the upper trim panel on the hatch! All of this comes with full color install instructions and great customer service & support!

2021 Turbo Mazda 3 spoiler fits with the body style well

So if you’re ready to take your GEN4 build to the next level, check out the CorkSport Performance Spoiler for 2019+ Mazda3. We think it’s what the OEM spoiler should’ve been and you will not be disappointed! Don’t be shy to contact us with any questions!

1st Gen Mazdaspeed 3 Carbon Fiber Spoiler

Are you looking for an exterior mod that will freshen up the look of your first gen Mazdaspeed 3? Well if that’s the case then the Carbon Fiber Spoiler is the perfect part to install on your build. The Carbon Fiber Spoiler retains the OEM look with the much-appreciated addition of carbon fiber. Keep on reading below for more info on the carbon spoiler.

Since the Carbon Fiber spoiler is based off of the factory Mazda piece, installation is a breeze and requires no drilling or other modifications to the hatch. We have also pinned the third brake light so that it can reuse the OEM connector with no modification to the harness needed! The Carbon Spoiler also comes with all the necessary hardware to install the spoiler so you can be back on the road in no time. Fitment with other add-on parts such as spoiler extensions or gurney flaps should work with the OEM style shape, however, we have not tested it. The same goes for GEN1 Mazda 3, the CF spoiler should fit, however, you may have a different 3rd brake light setup and/or have additional holes from the smaller Mazda 3 spoiler

Following the OEM MPS 3 design the top is carbon fiber with the bottom being a black gel coat

The Mazdaspeed Spoiler features a fiberglass base that is then topped off with a layer of carbon fiber on the top side of the spoiler. The underside of the spoiler is finished in gloss black and the whole thing is then coated with a UV-resistant epoxy resin to provide a mirror-like finish and the necessary protection from the elements. The two halves come together on the rear edge so there is a small seam, however, once installed, the seam all but disappears!

2021-up Mazda 3 Turbo and CX30 Turbo Intake Heat Shield

Cold air vibes for your Mazda 3 turbo

Have you been waiting for the CorkSport Heat Shield to go along with a CS SRI to snag one? Well you don’t have to wait any longer because the CS heat shield is here! Whether you have the CS SRI already or want to get both at the same time, the CorkSport Heat Shield for both the Mazda 3 and CX-30 with the SkyActiv 2.5T is a great mod to include in your build. Keep on reading to see how the CS Heat Shield is able to achieve lower intake air temps that allow your motor to make power easier.

Mazda 3 turbo engine bay intake heat shield

For the Mazda 3 Turbo Heat Shield our main focus was keeping cool air supplied to the filter. The shield was designed to seal off the intake from as much heat produced from the radiator, engine and transmission as possible. This lead to a multiple piece design that is riveted together which allows us to utilize the OEM air ducting which supplies cooler outside air to the filter. The shield does not fully surround the filter because we have also found that there is cool air that also comes from the area in front of the tire and underneath the headlight while driving, helping to ensure that your intake sees as much cool fresh air as possible.

Mazda Cx30 Performance Intake Heat Shield

Now with all of this cooler air being supplied, how does it help performance? The basic concept is that since cold air is denser than warm air, your engine gets more air per cycle, and thus allows more fuel to be added to make more power. However, when a car is turbocharged, the process is a little more complicated. A turbo compresses and heats up your intake air and then sends it to an intercooler that cools the air back down. What that means is that the “colder air will make more power” generalization may not be as significant, especially with the advancements in modern turbocharged vehicles. Colder intake air does offer a benefit in the form of less stress on your turbo system. This means that your turbo does not have to work as hard to flow the same amount of air at the same boost pressure. Also a reduction in intake air temps can translate to slightly cooler air exiting your turbo compressor, which helps take some stress off the intercooler as well.

With all of the theory covered, let’s get to the real world results! In daily driving testing we found decreased intake air temps with the CorkSport Heatshield installed. When cruising or when it’s cold outside, we were actually surprised at the low intake temps of the CS SRI alone—there’s actually a surprising amount of fresh air that gets into the engine bay. Where the heatshield really comes into its own is when sitting stationary or driving on a very hot day. That’s when we saw our biggest improvements in intake air temp.

3 cold air intake heat shield test data

Lastly about the manufacturing, the CorkSport Heat Shield is made out of carbon steel that is laser cut and precision formed. Carbon steel was selected for its strength and lower heat transfer over aluminum. To fight off corrosion, the heatshield is powder coated wrinkle black and gives the heat shield a great look that helps it blend in with the other parts in the engine bay. Both sections of the shield are attached together using stainless steel rivets for corrosion resistance and a nice look. Lastly, we include rubber seals along the top edge of the CS Heat Shield to keep as much heat out as possible, and to prevent any unwanted vibrations or noise.
