CorkSport Power Series Catback Exhaust

Mazda Catback Exhaust Installed

The Mazda 6 guys and gals have waited long enough! CorkSport is proud to announce the Power Series Cat-back Exhaust for 2014+ Mazda 6 models.

Mazda 6 Catback Exhaust Muffler

There are two types of Mazda 6 owners in the community: a person with a CorkSport Axle-back and the person that sadly still has the OE exhaust. Well sit back, grab a beer, and I’ll explain why that needs to change!

First, the cat-back exhaust sounds great! Watch the video below and compare the axle-back and cat-back exhausts. While they both sound awesome, you can tell the cat-back brings a whole new level of greatness. It’s not especially louder than the axle-back, but it provides a deeper rumble to the exhaust note throughout the RPM range. Best of all there isn’t a significant increase in cabin drone, so you can still enjoy your long cruises to the beach with friends.

Second, the cat-back exhaust looks great! Starting from the exhaust manifold, you have a thick, laser-cut flange that bolts right to the OE exhaust manifold. Following that is the machined O2 sensor bung that is precision-TIG welded. Next up are some multi-point hangers to get your exhaust in place with a large packing-filled resonator that helps manage the cabin drone we talked about earlier. Continue along those gorgeous lines of the Mazda 6, and you find yourself at the axle-back section. Here you will find two packing-filled resonators and two double-wall tips that only extenuate the curves of the Mazda 6.

Now that I have your attention, let’s talk about the most exciting aspect of the CorkSport Power Series Cat-back Exhaust. It makes power! That’s right ladies and gentlemen: More power could be yours if you improve your exhaust style and sound.

For an otherwise 100 percent stock car with no additional tuning, the improvements are impressive. I think the real turning point is the unsightly squashed section of the mid-pipe. Check it out below.

Yeah, that looks awful. Now let’s see the numbers. Check out this dynograph to see some other impressive curves. The Mazda 6 performs a whole lot better with the addition of the cat-back.

If that doesn’t convince you that the change is worth it, nothing will! Although, have I mentioned that the CorkSport Power Series Cat-back Exhaust is manufactured and CNC-formed from 60.5mm T-304 stainless steel pipe? It’ll look great for years to come.

It’s Finally Here: The Cold Air Box for Mazda 3 and Mazda 6

Designed to perfectly fit your Mazda 3 and your Mazda 6. Our cold air box is designed for easy install and easy filter maintenance.

We’ve heard your cries and made you wait long enough. The long-awaited CorkSport Cold Air Box has finally arrived!

Cool down your 2014+ Mazda 3 and 2014+ Mazda engine bay

The CorkSport Cold Air Box was designed for the 2014+ Mazda 3 and Mazda 6 that are equipped with a 2.0L or 2.5L SkyActiv engine. The CorkSport Cold Air Box was also designed with the current CorkSport SRI in mind, so all of our awesome past customers don’t have to buy a new SRI just to get the cold air box.

When we set out to develop the cold air box, we knew we needed to design it with more than just cold air in mind. It needed to look great, function great, and be easy to use. And that’s exactly what we did.

First on our list was figuring out how to perfectly source cold air for your engine.

Mazda has worked hard developing a car that’s highly efficient; one of the ways to do that is via the aerodynamics of the car. There can be sizable aerodynamic losses when a car has large voids and/or openings in the front, sides, and under the car. Mazda did such a great job with the aerodynamic design that there are no openings in the front of the Mazda 3 and 6 other than the radiator, but we don’t want to source hot air from the radiator.

This left us with two options:

1) Ask you, our customer, to cut holes in your brand new car or

2) Utilize the cold air source that Mazda already worked so hard to design.

This wasn’t a difficult decision to make.

The CorkSport Cold Air Box pairs perfectly with the CorkSport Short Ram Intake.

Through an iterative process of CMM (coordinate measuring machine), design, a 3D-print, and test fittings, we were able to design a cold air box that utilized the OEM cold air source and re-use the OEM rubber mounting isolators.

Designed to perfectly fit your Mazda 3 and your Mazda 6. Our cold air box is designed for easy install and easy filter maintenance.

Using the OEM rubber isolators and mounts allows the box to move and flex to account for the engine’s normal movement during operation. Pair this with the easy to use thumb screws for the lid and filter servicing is a breeze.

Get your 2014 Mazda 3 the cold air it needs with the CorkSport cold air box that goes perfectly with the CorkSport SRI.

Finally, we wanted the CorkSport Cold Air Box to look like it belongs in your engine bay. The color, finish, and manufacturing method were all chosen because they closely resemble OEM parts. Like most OEM plastic parts found in the engine bay, the CorkSport Cold Air Box is manufactured from ABS, which is durable and resistant to the high heat found in your engine bay.

Yes folks, this means you can have your cake and eat it too. Get it February 24th, 2016!

Cheers,

CorkSport

 

The New CorkSport Mazda 3 Rear Motor Mount

Feel like your SkyActiv-powered Mazda is lacking a bit of throttle response and driver feedback?

We hear you, that’s why we’re introducing the all new CorkSport Race Rear Motor Mount for 2014+ Mazda 3 and Mazda 6, as well as 2013+ Mazda CX-5.

CorkSport Mazda 3 Rear Motor Mount

Manufactured from 6061-T6 aluminum and anodized, the CorkSport Race RMM is strong, durable, and lightweight. What truly sets the CorkSport Race RMM apart from the competition goes to the 70a polyurethane. This RMM does not use polyurethane inserts that can loosen up and degrade. The 70a polyurethane is poured directly into the mount for a permanent bond with the aluminum body and bushing collar.

CorkSport Mazda 6 Rear Motor Mount

More than a handful of prototypes have been tested to ensure that the product arriving at your door is the very best it can be. We tested different durometer polyurethane from 60a to 80a (as well as different bushing sizes) to find the maximum improvement of throttle response and driver feedback without excessive noise, vibration, and harshness. Check out one of the prototypes below.

Now you might be thinking: “How does a motor mount improve throttle response and driver feedback?” In FWD vehicles it is typical for the engine to be oriented in a transverse layout. This means the engine is parallel to the axle centerline, whereas in a longitudinal layout (typical of V8’s and RWD vehicles) the engine is perpendicular to the axle centerline. Anyway, the engine/transmission applies a rotational force (torque) to the drive shafts, in turn rotating the wheels/tires forward.

“For every action there is an equal and opposite reaction.” – Newton’s third law of motion.

The amount of torque applied to the wheels is equal and opposite to what is applied to the engine itself, but what keeps the engine from just rotating? Enter the engine mounts. Unfortunately, the OEM engine mounts are very soft, so the engine is able to move and rotate substantially while driving. This makes for a very plush ride inside the cab, but sacrifices throttle response, driver feedback, and really the general driving experience. Replacing the RMM drastically reduces the amount of rotation the engine is allowed which in turn forces more of the engine’s torque to the tires sooner instead of just rotating the engine in the engine bay. This holds true for any action that affects the engine: throttle inputs, up-shifting, down-shifting…etc.

CorkSport Mazda 3 Rear Motor Mount

For just $129.99 you can’t go wrong. Improve your vehicle’s performance with the CorkSport Race RMM, and pair it up with the CorkSport Short Shift Plate and Shifter Bushings for the ultimate performance package!

So You Want to Go Racing in a Family Sedan?

CorkSport Mazda in NASA 25 Hours of ThunderhillNot too often do you get a chance to cage up your family sedan and “run what you brung,” but that’s exactly what Mazda and Robert Davis Racing (RDR) did in the 2013 NASA 25 Hours of Thunderhill. Mazda took three brand new Mazda 6 Skyactiv diesel sedans out to the track and ran them. There were a few on-track incidents in the 2013 race but nothing too serious. Mazda was lining up to run the cars again in 2014, and several things fell into place that allowed CorkSport to provide some additional power improvements to the cars. We outfitted them with a downpipe and exhaust made from 80mm stainless steel, a high flow intake system, an upgraded intercooler and piping, and some ECU tuning. This gave the cars more power to stand a shot at the podium in E1 with better fuel economy than the other class cars and more power than the previous year.

Inside the group of three Mazda Sedans was a rivalry of the Mazdaspeed Guys (comprised of Mazdaspeed Motorsports employees) and the Dealers CEB (Crayon Eating Bastards), a group of Mazda dealership owners/employees. The dealers controlled cars #55 and #56, and the Factory Guys (Mazda Employees) had #70, all fighting it out for bragging rights. Before the race got going #70 hit a snag where a coolant line came loose and overheated a motor, which prompted a Thursday motor change.

By Friday the cars were all in good shape for qualifying. This went down trouble-free despite a giant rainstorm, as if it wasn’t hard enough trying to run a fast lap with 58 other cars out on the track in six classes— all of which had different speeds.

Thankfully, by Saturday morning the weather had cleared up, and the forecast predicted dry racing for the full 25 hours. This prompted us to get the three cars ready to run on slicks which were mounted up on the wheels and installed on the cars.

Right at 11 am the flag dropped and started the longest race in North America. This was, needless to say, an adventure for the whole team. Several hours into the race, the driver of #70 reported that the car would not shift into all of the gears. It turns out the extra power was a little harder on the drive train in the higher gears, which removed the 5th gear from being functional. The driver decided to stay out and run the race in 6th gear until the fuel stop came up. That turned out to be hours later courtesy of the excellent fuel economy of the Skyactiv engine. The pit area was prepped for a transmission swap with a spare gearbox the team had brought with them. Unfortunately, this took the car out of any chance of being on the podium, but with endurance racing you never know what will happen! So the transmission change went ahead as planned.

At the first extended yellow flag session #55 and #56 reported a power loss in the cars. This resulted in a massive jam session to diagnose and fix what was going on with the cars. Since these specific cars live their lives on the track they did not get a chance to be tested with the new modifications at low speeds (AKA street driving speeds) which brought up an exciting challenge with the fire control systems in the cars. It took ~about 2 hours to sort out the problem, and we had the #55 and #56 back at full speed heading into the night.

Mazda Sedans drive into the night

The #70 was getting its final work completed with the transmission change and ready to head out onto the track again well behind the Mazda dealers in the #55 and #56 cars. Late into the night, after a driver change, we got a call in on the radio #55 had an on-track incident with another car in the E2 class, and sadly both cars had to retire from the race. This E2 class car happened to be leading the class which RDR was also fielding “Kermit,” the green RX8, in. Though the incident was unfortunate, as a result Kermit moved to the leader position of the E2 class.

Several hours later we got a call in from #56 of an off-track situation which required the car to retire from the race too. This put the #70 Mazda 6 in position to finish ahead of the #55 and #56 for total laps if its drivers could finish the race trouble-free. As the sun came up, the #70 car was running without a hitch, as was Kermit.

From sunrise until noon, the race for the two remaining cars was uneventful. At the noon finale of the race Kermit secured the win in E2 for the first time! Like in any race, there were things you learn and adjustments for the next time on the track. I want to give a huge thanks to RDR, Mazda, Mazdaspeed, the volunteer crew peeps , and Weldon for the guidance on my first time being a crew chief for an endurance race. Lastly, a big thanks to Ruandy from Pacific Northwest Life for the great camera shots—and to my family for letting me miss an entire weekend at another race.
