Mazda made some big improvements to the quality of the 4th GEN Mazda3 and one area that stands out in particular is the improvements to road noise. This is fantastic when cruising on the highway, but there’s one area that is just too quiet: exhaust. Luckily we have just the fix with the CorkSport Axle-Back Exhaust for 2019+ Mazda 3 & CX-30. Add some needed excitement to your Mazda 3 by adding some character to your exhaust note. Loud enough to enjoy during aggressive driving, but quiet for cruising and the daily commute. Check out the video for sound clips and read on for full details!#ZoomZoom!
The CorkSport ABE replaces the restrictive OEM muffler section with a high flow, pass-thru resonator that provides volume when you want it, but minimizes drone and excess noise when cruising. The GEN4 Mazda 3 axle back is an atypical design with an offset inlet flange. This led us to use a single, long resonator on one side. We even tested different resonator combinations and found the single resonator to be the best combination of great tone plus drone elimination. Be sure to check out the product video for sound clips!
The CS Axleback exhaust also ensures your 3 is not all bark and no bite. We increased the exhaust diameter from 50-55mm (depending on where you measure) up to 63.5mm. This diameter increase combined with removing the restrictive OEM muffler really helps your Sky-G breathe better. Dyno testing in a controlled and repeatable setup showed gains of 3-5wHP & 2-3wTQ across the RPM range. While not a huge number we are happy to see a gain and expect more when the CorkSport Mid-Pipes are also installed (coming soon!).
We did not forget about appearance. The rear end of the 4th Gens are let down by the too-small OEM exhaust tips. We increased their size up to 90mm to fill out the bumper cutouts. The CorkSport Exhaust uses a dual wall, slant cut design that is rotated to help match the curve of the OEM bumper. As a finishing touch, a laser engraved CorkSport name badges are added to really set off the look.
For the new Mazda 3 we also incorporated a new feature into the CS exhaust: tip length adjustment. Each tip is attached with a slip fitting and an exhaust band clamp that has proven not to leak or loosen up in use. This gives you up to 10mm of length adjustment to dial in your preference. That’s not all though. We have three different tip options to choose from: Mazda 3 Hatchback, Mazda 3 Hatch with Appearance Kit, Mazda 3 Sedan and the new CX-30.
We specifically designed two different length tips for the Mazda 3 Hatchback due to the design of the Mazda Appearance Package. The rear bumper skirt adds a lot of length to the car…hiding the tips from view. With the Appearance Package specific design, the tips are prominent in the rear bumper skirt as they should be. (The Hatchback Appearance Package tips are 45mm longer than standard Hatchback tips).
Each CorkSport ABE is made from fully polished, mandrel bent, 304 stainless steel. This gives a great look that will stand up to the test of time. To ensure strength, each joint is TIG welded and the inlet flange is laser cut for optimum fitment. Each exhaust comes with all hardware needed for installation and we even provide full color installation instructions!
It will take you two hours to install the CorkSport 4th Gen Mazda 3 Exhaust with our easy-to-use instructions.
