2 Hour Install
Would give 6* if I could, I purchased this exhaust system through Australia's only corksport distributor (wolf racing products in Sydney) I installed it yesterday on my 2015 Mazda 3 SP25 with no problems at all and I have to say it exceeds all the expectations I had for it. The sound is amazing when giving it the boot and she has a beautiful purr when cruising, it looks stunning in the polished stainless steel finish and the performance increase is definitely noticeable especially paired with the corksport SRI \ cold air box combination which I had installed a month earlier. I can't praise these products highly enough, anyone with a 2014+ Mazda 3 should have this system installed you won't be disappointed.
I am now even more in love with my maz than ever before.
Thanks to all the R&D guys @ corksport for making Mazda's kick arse again.

I installed my Corksport cat back yesterday on my 2018 Mazda 3 GT Sedan and I am beyond happy with it. The welds are superb, install was simple (kudos on the full color instructions), and the sound is exactly what I wanted.
I installed it at the dealership that I work at and everyone I work with was very impressed by how it sounded and looked. It continues to turn heads!
Thank you, Corksport, for making a wonderful product and helping get it to me quickly, as well.

Easy to install. Sounds amazing! I definitely notice the increase in power with the combination of the air intake to now the performance exhaust. Good customer service. I will definitely be a return customer.

Just installed this over the weekend, and it is such a wonderful sound. The startup is a little on the loud side, but it sounds deep and powerful for a 2.0L. 1000-1800 rpm is a very deep note. While 2000-3500 is a bit of a dead zone, it is convenient for cruising (very little droning). The sound picks back up in the higher range, but the cabin blocks alot of it.
Overall, very happy with the system. Major improvement over the factory exhaust. I will update after driving more

bought on black friday. got it yesterday, installed today. took about 1h45m to finish. sounds awesome!!!
(note: i had a hard time unscrewing the o2 sensor with the stock pipe still on the hanger so i droped the pipe and unscrewed it then. i also zip tied the slack from the o2 sensor wire to the new exhaust hanger.)

Fitted my Corksport cat back system yesterday and am very happy with it. It has a really deep bass note and was easy to fit. The build quality of this exhaust is amazing! Its a shame it is under the car where you dont see it easily. I highly recommend this exhaust and was very impressed with how my purchase was packaged and shipped. Great service Corksport, thank you.
I just bought my first mazda, 2017 Touring, manual trans sedan. My rear bumper does not look like that will it still fit? Where did you get a bumper that has cutout areas for the exhaust tips?
My brother just got this installed on the exact same car as yours. Just make sure to select sedan not hatchback. The sedan exhaust will have the tips angled slightly downwards. You won't have any problems with the fit.
Check with your local emissions laws. For Illinois it is https://www.dmv.org/il-illinois/smog-check.php The exhaust system does not trigger a check engine light.
Check with our sales team Sales@corksport.com to see if there are any special running.
Is the midpipe (the one that runs from the catalytic converter, just in case) included in this item, or is that meant to be selected/purchased separately? (In other words, what "comes in the box" with this item?)

This is everything after the stock exhaust manifold.
I have a 2015 Mazda 3 Sport with a 2.5 motor and the vehicle as the factory Aero-Kit with rear diffuser (PN: QBMA-50-360 -PZ).
Will I have any issues with the exhaust tips hitting the rear body panel?
Same question if I lower the car using the Corksport lowering kit?

For the 13 or so states that have adopted clean air laws similar to California's (such as Maryland), would a cat-back be legal in those states, or is replacing the secondary cat converter down there illegal?
Would the Corksport midpipe designed for the hatchback fit on a sedan? For example, does the hatchback have a difference length midpipe than the sedan. Or is the only difference between the hatchback and sedan version is how the exhaust tips are angled?
If I have already bought the Axel back exhaust for sedan but now have decided I want the Cat-back, is there a way I can buy the rest of the mid pipe without having to buy the entire exhaust (seeing as how I already have the axel back portion)
Can I attach the muffler for the sedan cat back exhaust directly to the OEM mid pipe like an axle back install? I'd like the option to not have to run the CS mid pipe assembly if I purchase the cat back system.
It would pass smog in most states, but not in California due to their strict emission standards. If they simply do an OBDII check it will pass, if they do a sniff check it depends on the specifics. If they do a visual inspection to make sure it is OEM, it will fail.
