Ever wondered the key factors of making a decision about your aftermarket exhaust? Why Cat-back?
Is it the diameter of the exhaust that says performance? Or is it the type of metal used? What about fitment to your current setup? None of these questions by themselves answer what you need by themselves, but all of them together help when making the decision on how to get more power out of your Mazda.
At CorkSport, we have made it our #1 priority to make our customers dreams a reality. Whether you drive a Mazdaspeed or a regular Mazda, we’ve made sure to engineer a great fitting exhaust that maximizes engine performance.
Check out the Cat-Back Exhausts by Car Model Below:
Take the Mazdaspeed 3 for example: When you purchase a CorkSport Catback Exhaust, you’re getting T304 stainless steel piping that has been polished to a mirror-like finish.
You’re also getting true 80mm piping, which is slightly bigger than three inches, making our exhaust one of the biggest bolt on catback systems.
Fitment is also a big concern to us. We make sure our exhaust systems are mandrel bent and TIG welded to make a perfect bolt-on fitment.
Now that you know our exhaust is 80mm piping, polished to perfection, and made to be a direct fitment, you can bet this exhaust will increase performance and sound. By installing our cat-back exhaust, you’re removing the secondary unmonitored catalyst making the exhaust flow much faster out of the motor. By increasing the velocity of exhaust gases out of the motor, you increase power and make your turbo spool up a little bit faster.
Among the power gains you’ll see from installing the CorkSport Catback Exhaust, you’ll also have a car with a deep growl to it. Our exhaust has one of the best sounding tones on the market. With a quality made exhaust, comes quality sound.
With our goals to make more power, we often forget about the opposite requirement so speed…stopping. The CorkSport Big Brake Caliper Kit is a great place to start, however, if you wish you could stop even faster say hello to the CorkSport 13inch Big Brake Kit. Designed for serious stopping power, it includes 13” directional rotors, powder-coated 4-piston calipers, upgraded pads, and everything you need to install it on your Mazdaspeed 6.
Read on for a breakdown of all the components:
Lots of thought has put into the design of the performance rotors found in the CorkSport 13inch BBK. The upgrade to 13inch diameter rotors provides greater braking torque for an equivalent braking force (like how a longer wrench makes it easier to loosen a tight bolt). The increased diameter combined with a thicker 28mm (vs 25mm for OE) rotor ring provides better cooling as there is a larger mass to reject heat into.
In addition, slots were added to the friction surface to help sweep away any debris, brake dust, or gases that can otherwise affect your braking characteristics. Drilled rotors were not used as holes decrease your total friction area and increase the chance that the rotor will crack. Utilizing a two-piece design, we were able to decrease the overall weight of the rotor via center section produced from billet aluminum; while also helping dissipate heat from the rest of the rotor better. Semi-Floating mounting between the inner and outer sections allows for quieter rotor vs having a full-floating center section.
Lastly, the rotors feature directional internal vanes that promote more efficient airflow through the rotor which further increases the rotors ability to dissipate heat. By using curved vanes instead of the typical straight vanes, the rotor becomes directional and has to be used on a specific side of the vehicle; however, it also provides more efficient cooling. When the rotor turns, the curved vanes draw air through the center of the rotor and out through the edge, providing greater airflow than a straight vane and thus better cooling. There is another bonus to heat dissipation as the curved vanes have a larger surface area that will come in contact with air than an equivalent number of straight vanes.
Four-piston performance calipers manufactured from forged aluminum are included with the kit in a choice of powder-coated blue, red, or black.
Although each piston is individually smaller in diameter than the single OE caliper piston, the total surface area is increased so the braking force at a specific brake pressure is increased. Larger piston surface area means larger brake pads can be used as well. You also get more even braking force on each side of the rotor due to the opposed piston design. This encourages even pad wear, even rotor wear, and consistent braking characteristics. The piston diameter and material were chosen for optimum braking endurance and reliability. They are staggered in size, with the pistons on the leading edge being slightly smaller than the trailing edge pistons. This is another protection for even pad wear. Each piston is made completely out of stainless steel for its low conductive heat transfer. What this means is that the pistons themselves will transfer less heat to the brake fluid than an aluminum or steel piston, decreasing the chances of overheated brake fluid.
Street performance brake pads are included with the kit. The street sports pads bridge the gap between street and trackpads. They are a more aggressive compound than the pads included with the CorkSport Big Brake Caliper Kit but are not a fulltrack pad. They will produce less dust and noise than a track pad but still need to be warmed up for optimum performance. Should you need new pads or want to change to a different pad, you have a bunch of options from G-Lock, Carbotech, EBC, Hawk, and various other manufacturers.
Lines, Brackets, and Hardware
The remainder of the CorkSport 13inch BBK is composed of exactly what you need to properly and safely install the kit on your MS6. Coated stainless steel brake lines are included to remove any risk of a soft brake pedal and ensure the calipers are operating optimally. High strength billet steel brackets properly position the four-piston calipers on the new rotors using the OE bracket locations. All components are locked down using Grade 12.9 hardware with a corrosion resistant coating for lasting durability.
The Mazdaspeed 3 and Mazdaspeed 6 are some of the most unique, exhilarating, and frustrating sport-compacts out on the market today. If you’re reading this, then it’s because you are in the market for a Mazdaspeed or you have one already and are looking for a good laugh. For you are newbies to the Mazdaspeed game…listen up; we’ve got some words of advice and things to check as you are shopping around.
First, let’s start with the top two must do inspections when shopping around.
One:Has the car been modified? If so then what parts are on the car and has it been properly tuned for the parts. This also means the car should have some type of tuning tool such as the Cobb Accessport or Versatune Tuning Solution.
Two:You MUST check the engine compression! This is the easiest way to get the overall health of the engine and know if you are getting a solid Mazdaspeed to start your journey with or a Speed on it’s last leg. Most auto parts stores can loan an engine compression tool for a small deposit then only basic hand tools are need to do the test.
Now let’s get the top five things you should know before buying a Mazdaspeed.
Maintenance is KEY, but that’s really not special to just the Mazdaspeed, all performance engines/vehicles, especially turbocharged and direct injected ones, will require a higher level of care and cost when it comes to routine maintenance. This means better quality oils, oil filters, premium grade fuel, and an acute awareness of the vehicle itself; if you’re ready for that than let’s move on.
Next up are the three “not if it happens, but when it happens” about the Mazdaspeed engine.
The variable valve timing (aka VVT) system is prone to failure from the factory so this should be on your radar for an upcoming replacement. You may get lucky and find a car that has had the VVT system replaced, but I wouldn’t plan out. It’s a medium difficulty project that can be done over a weekend and cost around $400 in parts. If you are not mechanically inclined, it is going to be expensive to have a shop perform the work.
The poor little OEM K04 turbocharger just never had a chance on the 2.3L DISI MZR engine! Sadly, the OEM turbocharger is an honest to gosh ticking time bomb. The OE turbo will fail at some point and need to be replaced. Fortunately there are a lot of exciting options on the market to take you and your Speed to the next level. For example check out the CorkSport Drop-In Turbocharger. It bolt’s in like OE, but packs a punch in the performance department, supporting up to 450 horsepower. Note: Updating your turbo requires tuning.
Lastly for the Mazdaspeed quirks; the high pressure fuel pump internals (HPFP). Like the name states, these parts provide an upgrade for the camshaft driven high pressure fuel pump so your engine does not experience fuel starvation during wide open throttle (WOT). These are absolutely required if you plan to make in modifications to the engine that would increase power and for any performance tuning. Honestly, we recommend the HPFP internals for 100% stock Mazdaspeed as well because the drop in fuel pressure is even an issue for stock cars.
So you read all that and you’re probably thinking “damn I’m not buying a Speed, sounds like a total PITA”. Well hold on, I didn’t mean to shine a poor light on the Mazdaspeed platform, but it does have its quirks to overcome. However, after those few concerns are taken care of the platform is A LOT of fun and probably one of the best bang-for-the-buck sport compacts available. Just a few thousand dollars can net you a Mazdaspeed around 350whp and more smiles than you’ll know what to do with.
The last thing you need to know before you buy a Mazdaspeed…jump straight in and don’t look back because you won’t regret it. From the late nights in the garage installing the latest performance parts, to the early mornings at the car show, and then the midnight highway pulls making V8s owners second guess their purchase. The community, the journey of building YOUR car, and of course the car itself is so awesome.
The Top Five Things YOU NEED to Know Before You Buy a Mazdaspeed September 13th, 2018CorkSport
The GEN2 Mazdaspeed 3 has a lot in common with the Mazdaspeed 6 and the GEN1 Mazdaspeed 3 when referencing the engine and transmission. However, there were a few things that Mazda did change and improve when they gave the Mazdaspeed 3 a facelift in 2010.
Some of these changes include the valve cover, the gear ratios in the transmission, the power steering system, and the oil filter assembly. This last one is the one I want to talk about today.
Perhaps you just ran across this blog while googling how to change the oil in your Mazdaspeed for the first time or maybe you’ve already done a handful of oil changes. Either way, you can benefit from this info, unless you already have a 2010-2013 Mazdaspeed 3 you lucky bas****. All you Mazdaspeed6 and GEN1 Mazdaspeed3 owners listen up.
This is what you’ll find on your pre-2010 Mazdaspeed 3 and all Mazdaspeed 6; it sucks. This design uses an internal filter element only which is fine, but the OE housing cap is a real PITA to remove from the car which makes a simple oil change a much more frustrating process than it should be.
Along with the difficult disassembly, there is a limited number of filter options compared to the modern canister design. Luckily, the oil filter housing found on the 2010-2013 MS3 utilizes a modern canister oil filter and is a simple bolt-on affair.
Mazda part # L311-14-311A is the part you’re looking for and can be found online or at your local Mazda dealership. It’s also wise to get a new gasket for the installation; nobody wants to do a job twice. This is Mazda part # LF02-14-342.
Once you get your parts and all your oil and new modern oil filter, you’re ready for the big install. It’s actually really simple, only adding about 30 minutes to your oil filter change. Remove the fluid-to-fluid heat exchanger (the black thing on top with the coolant ports), then pull the housing off the engine and swap over the sensor. Back on the car with the new gasket and you’re good to go.
Another great benefit of the modern oil filter canister is the ability to use an oil filter plate to provide sensor ports for gauges such as oil pressure and oil temperature.
This sums up the oil filter housing swap; it’s really just that simple. So if you have an oil change coming up and aren’t one of the lucky ones with the GEN2 Mazdaspeed 3, then consider this before you get started. I promise you won’t regret it.

People sometimes seem to forget that quality of your tune is just as important as the quality of your parts. So how do you get a solid tune on your car?
CorkSport wanted to make sure to lay out exactly how to prepare your Mazdaspeed for tuning services. This helps streamline getting your Mazdaspeed ready, and it also helps your potential tuner so they don’t have to worry about tuning with a potential mechanical problem.
The very first step in getting your Mazdaspeed tuned would be to get the Cobb AccessPort tuning device. This is the gateway to access your ECU and to make adjustments to your tune. You will use your AccessPort to record logs and send those logs to your tuner. Not only can you make adjustments to your ECU, but you can also read/clear CEL’s ( check engine lights), and you can also monitor up to six different parameters in real time.
When you do apply for a tune, your tuner will tell you which parameters to monitor so they can have the correct information to get you a reliable tune.
The stock high-pressure fuel pump internals has proven to randomly lose pressure during a fourth gear wide open throttle pull. What we have seen is the pump spike pressure up in the 1800’s, and by redline, the fuel pressure has dropped below 1600psi. This creates lean situations which have lead to engines grenading themselves. Before a tuner will touch your car, you will have to make sure to have these upgraded. These will increase flow and allow your fuel pressure to stay above 1600psi keeping you in the safe zone.
Double check what your tuner will want you to use, but in general, people will use one step colder plugs gapped down to a .026. The trusted spark plug in this platform would be the NGK Iridium IX plugs (part # 6510). The idea behind using a more quality plug with a smaller gap is to keep the spark from blowing out when you increase boost pressure. If you do have too large of a gap, then you will start to misfire, and you should get a code on your AccessPort for either random misfire, or cylinder specific. Keeping that spark in check will prevent delays in the tuning process.
Making sure to double check the engine health is probably one of the most important things to do before modding and tuning your Mazdaspeed. Doing a quick compression test to make sure your cylinder rings can still hold pressure will tell you if the engine is healthy or not. Ideally, you want to see all of your cylinders read approximately the same numbers.
You also do not want to see your compression go below 140 across the board. Mazda says that anything 140 or below is poor compression. If you end up having an unhealthy engine, then the car will not make the desired power, and you could potentially ruin your engine even further. Make sure to check out our misfire blog where we show you how to properly boost leak test your car!
Every tuner is going to be targeting a certain boost pressure based upon current modifications. A lot of times the turbo has to work harder because of a few boost leaks that are not closed off before tuning. This can affect your fuel trims, and it will also affect how much wastegate duty cycle is needed in order to reach desired boost targets. Having zero boost leaks is important so your tuner does not have to work around those leaks.
A big question we always see in the forums, and on Facebook would be people wondering why their AccessPort shows knock values. The most important thing to remember is part throttle knock is nothing to worry about. My own Mazdaspeed see’s values of 8.0 all the time on part throttle. The only time to worry about knock values is when you are at wide-open throttle. As long as your knock values stay below 2.0 then that is nothing to worry about.
Doing these few simple things for your tuner will not only save time for both of you, but your tuner will love you because they don’t have to try and diagnose an issue from thousands of miles away. CorkSport hopes this really helps the community as a whole, and we also hope that people can use this as a tool to get their car dialed in much faster.
Stay happy, and stay fast CorkSport family!
