JUST got this after months of waiting and I must say, it was worth the wait. I love it; just wish the tips were a bit more pronounced, but still awesome.

I bought this exhaust system for my 2015 Mazda3s GT with an automatic transmission. I could not be happier with the system. The quality of materials and workmanship is off the chart. Fit is perfect, with no leaks. And the sound. The sound is perfect as well, very quiet at cruise with a nice growl under acceleration all the way to redline. Reading forum posts about this exhaust made me concerned about the sound level, but nothing could be farther from the truth. This exhaust is not loud at all. Just enough volume and a great tone, to make the car feel special.

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.
