I don't ever write reviews about products I buy but had to for this product. I'm Really pleased with the craftsmanship, customer service, and overall quality of the exhaust. The videos that people post on youtube don't do it any justice. I was kind of "iffy" about it when I watched those videos but they don't capture the deep and refined sound that surprised me when I first started the car. It doesn't sound like a can of bees by the way. If you're interested in this exhaust, I highly recommend it!
Sound wise, the axleback sounds way better than stock, specially at lower rpm, although at times it doesnt sound like it's even there. The real surprise for me is at the acceleration. I've read better that the axleback exhaust doesnt have any hp gain, but after installing mine I really notice a more linear/smoother acceleration. Where as before if tends to dip when I floor it before accelerating aggressively and then dipping again.
Overall very please with the performance. I might add an aftermarket midpipe in the near future.
The exhaust shipped quick, and it sounds great. However, mine showed up with 3 scratches/chips on the left tip. the first day I had the exhaust on my car the exhaust tip had 3 noticable rust spots from the scratches/chips. Even if this is covered by warranty, I live in Canada so I will have to pay $320 in shipping and customs fees for a replacement exhaust. I thought everybody should know before they purchase.
Agree with all other posts about nice sound, great looks, etc. I have mine paired with the SRI and cold air box, 2016 Mazda 3 sGT. It's louder for sure at low revs and upon cold startup, but not too bad. It's actually quieter than stock at idle. The deep tone is awesome and it looks really sharp. I have the factory appearance package installed, and there was no trouble at all fitting this around the rear diffuser - clean install. One tip though is that the OEM muffler assembly really requires a deep 14 mm socket - standard won't cut it for the removal stage. I added deep 17 mm and 14 mm sockets to my tool box for this install and would highly recommend it. Total leisurely install time from starting to get tools out to finished cleaning up, including the trip to get the deep sockets = 3 hrs. No sweat.
Just got this exhaust on. It sounds pretty good. It DOES drone at about 1500 rpm with little to no throttle (slowing down for stops), Sounds like a sub-woofer. However that's a pretty normal side effect when going for as deep of a tone as this exhaust has. It's not quite as loud as I thought it'd be. Just slightly louder than stock, but great for a daily driver. Overall pleased. Just wished someone had mentioned the small amount of droning in a review.
I ordered an axle back exhaust for my Mazda3 2015 SP25GT sedan. It arrived promptly to Perth, Western Australia, very well packed and in perfect condition.

I was very pleased with what was obviously a well made product. It fitted perfectly, looks good and sounds just as good as I hoped it would be. I can only add that it was a pleasure to do business with Corksport and I will be recommending Corksport to everyone I know. Thanks again. Robert
The CS axel back for the hatchback will absolutely turn heads. It sounds great. It's deep and loud but not annoying. It sounds right. Personally I think the sound gets better with a little time too. Very easy to install and looks great when your behind the car.
Picked up an axel back exhaust and short ram air intake for my 2014 Mazda 3 s GT hatch. I’m lucky enough to live 11 miles from their shop so I saved some $ on shipping. Installed the air intake myself without issue in about 30 minutes. However I decided to take the exhaust to my local muffler shop. Glad I did. My Mazda 3 has the appearance package which comes with a high gloss black rear bumper diffuser. I believe it’s a little larger and lower than the stock bumper. Once they had it installed (yes it is a quick bolt on unit) we noticed the rear exhaust pipes were recessed in by about 2 inches inside the plastic of the bumper. You couldn’t see the tips nor the Cork sport logo. Needless to say the mechanic was concerned about me melting the bumper. The easy fix was for him to weld a 2.5 inch pipe extension to the straight portion of the exhaust pipe, forward of the bolts. In the end the exhaust looks awesome and sounds amazing and along with the new air intake I definitely notice a boost in performance.
Either its one guys spamming for sedan or the sedan is going to be more popular, that being said I am interested in the Sedan version too!
So four months ago you said "Coming soon" for the sedan version. How soon is soon?

Also do you need to do a tune when these are added to compensate for the change?
Sounds Amazing! Easy enough to install... Deep growl like a 370z/g35 exhaust note not like a ricer civic with a high pitch annoying noise... Exactly the exhaust I was looking for!
What makes this product only available for the hatch? If it is simply because the rear diffuser blocks the mufflers on the sedan, I have already considered cutting holes and bringing them out on my sedan (I don't like hiding them) so that would be no problem. Or is it an actual installation issue with the differences in length?
Does this exhaust fit the 2014 2.0 sky active hatch?
Sedan version please!!
The sound on the video was poor....and that was the 2.5? 2.0 is far more prevalent. Point me to a video of that.(2014 3 iGT)
Is the reason why this doesn't fit sedan because of the sedans rear diffuser? Remove sedans diffuser would this axle back exhaust fit it then?
Does this need CS SRI installed first before applying the exhaust?
I want sedan version , anyone driving the gremlin is not a sports car give us sedan
still waiting for the sedan version. i prefer this than the magnaflow
do you guys have a time line for when the sedan version is coming thanks
make it for the sedan.. your losing money
Anticipating one for the Sedan 2.5Litre PLEASE!!!
For those urging the production of the sedan exhaust, you guys don't have a rear bumper that has exhaust cut outs. There first has to be an aftermarket bumper with dual cut outs before corksport can come through for you guys. If this exhaust could some how magically fit, your stock bumper would start melting due to the tips pressing against raw paint and plastic.
Would this fit on the sedan?
Sedan version please! How long till we can expect one to be released?
Will this work for my 2.0 2014 skyactiv hatch?
Come on, make it for the sedan already!! Just kidding. I have the hatchback and this exhaust rocks! It has a pronounced deep note up to 2100 RPM and still noticeable in the higher revs under 70 MPH. Cold start produces quite a bit of done until the RPMs settle. This may be desirable to some or quite the opposite to others. I find it a little much but it is only for about 45 seconds anyway. Always a reminder that I'm not sporting no stock exhaust!

Tip, when in Automatic (D) and decelerating use your paddle to force the downshifts and aim for 1700-2200 RPM while doing so. Makes such a nice, deep "BRRRUMMMMMM" when doing so. All others already stopped at the light / sign will quickly take note that "that cannot be stock on that Mazda!"

I was very concerned about highway drone since I spend about 80% of my time on it. I can confirm that at 70 MPH cruise control there is no drone....on level surface. When on a moderate incline, a little drone sneaks into the cabin. With music going or conversation, barely noticeable.

Lastly, the new exhaust note is always present to some degree. However, I noticed at highway speeds and flooring the gas to pass, the loud engine revs cover up the exhaust note

2014 Mazda 3 S Touring (5259 miles) 2.5L

I'm a little confused as to what happens to the catalytic converter. In the "cat. back" application, the factory exhaust is decoupled at the down pipe, which appears to be ahead of the converter. Does the mid pipe resonator also function as a converter? Please set me straight.
