Wake up your 2014-2018 Mazda 3 with the CorkSport 80mm Cat Back Exhaust. The next step up in volume from the existing 60.5mm CorkSport exhaust; the 80mm variant offers a great sounding, loud exhaust that doesn’t ruin the daily drivability of the MZ3.
More power, better looks, and a sound that changes a boring daily driver into a fun backroads car all come in an easy to install package. Plus, the large diameter piping future-proofs your ride for upcoming CorkSport parts.
We strongly encourage you to watch the product video below to get a sense of the volume and unique tones that come with this exhaust! For full information, check out the details below.
The sound is the true unique feature of the CorkSport 80mm Cat Back Exhaust. The 80mm piping really lets the SkyActiv-G engine sing, even more so than the CorkSport 60.5mm variant. The increase in volume also comes with some fantastic & unique tones that make hitting a curvy road exciting. We didn’t just copy the original 60.5mm design though and make the pipes bigger, we went through multiple resonator designs to get the best sound without ruining the drivability of the Mazda 3.
Adding Power & Room for ftuture Mods
By replacing the restrictive stock exhaust with large diameter mandrel bent piping and high flowing resonators, we are able to gain some much needed horsepower. When compared back to back with an OEM exhaust, the CorkSport 80mm made 5-7WHP. No tuning or part changes other than the exhaust swap. This will pair well with future GEN3 parts in the works that will probably need that extra volume for optimal power. And who ever said planning ahead was a bad thing?
The aggressive sound comes with an aggressive look to match. Each exhaust tip has been enlarged to 100mm (just under 4”). For the hatchback, these tips are dual wall & slant cut to match the bumper shape and fill out the cutouts. For the sedan, single wall tips are used to ensure water and debris don’t build up in the turn down. In each case, the exhaust accents the rear of the car to give an aftermarket look that is stylish and the way it should have come from Mazda.
High Quality Materials & Manufacturing
Each exhaust is made from fully polished T-304 stainless steel that is TIG welded together. This combo makes for a great looking exhaust that will last as long as your Mazda. All the flanges are laser cut for consistency and 9mm (~3/8”) thick to prevent warping. This package is wrapped up with high strength hardware, full color install instructions, and all the gaskets you need for a painless install.

It's a great exhaust system that pairs well with the intake system. I had my car tuned with it all and she performs beautifully. Definitely can't keep spare change in the console anymore and you'll know about every loose piece of plastic in your car. Don't underestimate the noise and vibration this produces, moreso the vibration. I think it sounds great and it makes me smile every time I hammer it. Would recommend if you like loud cars.

How loud can your Mazda3 be?
Very loud. Its not the noise that gets you though, it is the vibration. I expected as much noise as I got (Which is much more than you might think) but i drastically underestimated the amount of vibration. This is not to say that there is no comfort in the ride anymore. On the contrary, there are several points at cruising speeds where the car sounds nearly stock. You will have to adjust your driving style to find these points and cruise comfortably.
There are noticeable gains when paired with the short ram intake and cold air box. On acceleration, The vibration hides the extra power but I was at 80mph long before I realized.
Had it professionally installed and it took about 1.5 hours. a good amount of that was unwrapping the plastic.
Do take careful consideration in buying this, there will be no sleeping children in the car if you have this installed. IF you dont care about that stuff, it will put a smile on your face every time you step on the gas. :)

Is it loud? Yes, it's really loud. I can't enjoy music the same way like before. Do you feel the vibration? Yes, you do. Every time you step on the pedal, you feel it in your seat. As they already said, consider this carefully.

You want your Mazda6 to sound as good as it looks, get this exhaust. This is the first aftermarket exhaust I have purchased and installed, and the overall experience was better than what I expected. I have access to a lift so the installation was painless. I also purchased exhaust hanger pliers (like 15$ on Amazon) as they were recommended (not required) by the installation manual, and they made the installation even easier. I’m in my 40’s and didn’t want some annoying sounding exhaust I hear driving by all the time. Although the exhaust is louder than I expected, it’s at all the right times. Just what I was looking for. Cruising speeds are a quiet, low, deep sound with very little to no interference with in-cabin phone calls or your favorite music. Then, when you give it some gas, it sounds like what I would expect a high performance exhaust should sound like for this car. I am glad waited for CorkSport to release this exhaust made specifically for the Mazda6 instead of picking up the more universal Magna Flow cat-back. Under medium to heavy acceleration I do get a slight plastic vibration sound emitted from the passenger door sometimes that I can’t seem to nail down. Probably the only other non-issue for me is the how loud the exhaust is during the 45 seconds after starting the car. The computer adds extra fuel to warm up the catalytic converter faster and that 45 seconds is loud, after that it purrs like a lion.
