2021+ Mazda 3 Turbo 80mm Cat Back Exhaust System

The 80mm CBE is the ultimate exhaust for those who want the best sound and performance out of your Mazda. The tone is more aggressive than the CS 63.5mm CBE, but refined at the same time giving it the best of both worlds. Check out the sound clips below to listen to what your Mazda will sound like with the CS 80mm Cat Back Exhaust.

The 80mm cat back was optimized for the SkyActiv-G Turbo engine, but will also fit the AWD non-Turbo models if you want a louder more aggressive exhaust tone.

The CorkSport Advantage

Best Mazda 3 Turbo Cat Back 3-inch Exhaust

Optimized Sound:

The CorkSport 80mm Mazda 3 Catback Exhaust was designed specifically for the 2.5L SkyActiv-G Turbo engine as a complete cat-back with unique dual chamber resonators. Because of this, the 80mm exhaust will only be sold as a cat back.

When increasing the piping diameter, commonly more drone is created which is annoying to drive with. We developed the dual chamber resonator specifically for this engine to combat drones in both high and low frequencies.

While retaining the same unique asymmetrical axle back design; we went through multiple resonator setups and this combo proved to offer the best sound with the least drone so you can enjoy the best of both worlds while driving.

Horsepower Gains:

The Mazda 3 Cat-Back Exhaust provides improved horsepower and torque across the entire RPM range vs the OEM exhaust system when tested on a Mazda 3 Turbo model. Gains of 5-13wHP & 5-23wTQ were measured with a DynaPak chassis dyno on an otherwise stock vehicle. After installing, there is no tuning required for your Mazda. Depending on your mods, you may achieve a higher power potential.

OEM Fitment:

Fitment was a major part of the development of the CorkSport 80mm Mazda 3 Cat Back Exhaust. We went to great lengths to ensure that the fitment matched the OEM quality so the installation is spot on. We checked fitment with the stock hatch bumper, appearance kit bumper, and sedan to ensure all setups look and fit as good as the CS 80mm CBE should.

To provide great ground clearance and ample room for the drive shaft, the exhaust was tailored to fit the vehicle.

2021+ Mazda 3 Turbo 80mm Exhaust material

Materials & Manufacturing:

The CorkSport Mazd 3 80mm Cat Back Exhaust is constructed from 304 stainless steel, mandrel bent, and TIG welded. The Cat Back is then fully polished to provide a great look. We have reinforced the hangers with extra support to make sure they will withstand harsh driving conditions.

Well the only bad reviews were for the drive shaft rubbing but they include an entirely new exhaust hanger bushing now so I didn't have that issue. I absolutely love it, it rattles my garage when I first start it in the morning it's so loud on start up I can't even hear the seat belt chime. Really impressed how deep and choppy it sounds especially just idling. Looks beautiful installed, sounds incredible, power gains on the top end, car doesn't even vibrate anymore when you're at a red-light in drive with your foot on the brake. If you're even remotely interested in purchasing this product I'd say just do it, no matter how I look at it this exhaust it was an upgrade in every way.

Absolutely outstanding exhaust! Has a very deep and throaty roar that only improves with time. Engine/throttle response is also greatly improved, and there's no longer a slight hesitation after getting on the throttle. Running this in conjunction with the BMS Stage 1 intake for the time being and it's definitely a nice-sounding, free-breathing combo.

For Install -
Highly recommend utilizing at least 4 jack stands, due to the Downpipe>Midpipe connection being hard to reach otherwise.

Also, while not specified in the "Tools Needed" section of the instructions, a 22mm Wrench (not Socket) is needed, in order to remove the O2 sensor. Fortunately, a neighbor was kind enough to let me borrow an adjustable wrench, and after repeated swear words and "love taps" on the area around the O2 sensor, I was able to get it off.

All in all, I highly recommend this exhaust to those that both want to increase your performance and scare the local wildlife. 10/10

Easily best sounding exhaust for the 3, very throaty exhaust tone brings a whole new life to it! Should be on everyone’s wish list or future mod list!!

Conner Davidson01/18/2023, 10:42 AM

Wow! I love this pipe! I had previously purchased the air intake, and subsequently the heat shield, and loved the turbo sounds released. Now there is a great sound at the rear end as well. It has a very nice tone and is very streetable without being obnoxiously loud. There is also a noticeable increase in responsiveness. It took me a little more time than the 2 hours but I'm sure that varies and I had to get a new air gun mid-stream especially to get the front exhaust bolt on the driver's side. I highly recommend this quality made exhaust system!

Cant go wrong with corksport parts

The girth the bubble butt jelly bean/egg car needs and deserves. A nice deep note with a pleasant in cabin experience (and mine is stripped out with some sound deadening) but also sounds great in a stock interior. Greatly helps the butt dyno feeling and there's little to no doubt people are going to turn heads in many types of vehicles. Compliments have come in from everything under the sun so far.

Cold starts will get attention, and parking garages are fun again. The car gains a bit of low and mid range power with the exhaust girth freeing up turbo spool removing air flow restrictions on our tiny turbo.

The added downpipe once available to the public just makes every aspect even better, giving the car a MEAN growl.

Like a fine wine, this exhaust only gets better with time! The wizards at Corksport have somehow perfected the tone and volume of this exhaust; quite aggressive and pronounced when on the throttle (though not obnoxious), and subdued yet still noticeable when not.

As for my experience with the driveshaft contact issue: I used the Corksport provided extended exhaust hanger and had no issues. Aside from some standard mishaps to be expected, everything went in and aligned as designed!

Love it!

Thank you for making a tough sounding exhaust! Got a compliment from an Audi R8 driver. He said it’s the best sounding car he’s heard in this class of car. Made my day!
I wanted to respond to the review talking about the driveshaft rubbing on the exhaust. I had the same issue. CS has quickly responded to the issue by developing an extended midpipe hanger to help lower the exhaust away from the driveshaft. They shipped out a kit to all customers automatically for free. Thanks CS!

10/10 sound. not too loud not too quite. 10/10 welds. reason i’m giving a 3 star is because the fitment was off. followed the instructions and aligned the flanges and gaskets perfectly but the exhaust ending up rubbing on the driveshaft and taking some paint off. i had to readjust the exhaust by pulling it away from the driveshaft and retightening all the bolts down. everything is good now but now i gotta repaint my driveshaft before it gets some rust. other than that well built exhaust and solid sound.

NOTE from CS: an extended exhaust hanger has been provided for all effected customer free of charge and quickly once the interference was identified.

Love my exhaust! Fit requires careful following of instructions, will rub the drive shaft if not mounted properly. Performance and sound is AMAZING! Sounds like a proper performance vehicle instead of a quiet little sleepy thing. There is some drone cruising at highway speeds, but it's minimal.
