I agree with Dylan in the previous remarks. This exhaust is very quiet. Fits great and looks good but the sound isn't much better than stock, just a little deeper. With minimal gains in HP, CBE's are used primarily for sound, which makes me wonder why CS went this route with the quietness of a pricey exhaust. The video is deceiving.

Well I posted a review in November when I first put it on my speed 3 and I rated it a 5 star. One thing that I did notice is that the bolts that were used as well as the hangers are starting to rust. I paid almost 1500 for the full system and it still sounds awesome, but I was very disappointed in the rust that I saw on the bolts and hangers.

Steve09/30/2014, 10:19 PM

This exhaust sounds mean...... I hopefully will have it shortly. A buddy of mine has the turbo back, its a" lioness" at grandpa speeds but a "mean #$$" lion at WOT! Puts sabarus to shame.

Matt Harris09/30/2014, 10:18 PM

Just installed. Very nice deep tone. Would definitely buy again.

Evan09/30/2014, 10:18 PM

Sounds good nice deep sound and looks very nice

Jakub Gurgul09/30/2014, 10:18 PM

Very mis leading, i bought this exhaust and installed about 3 months ago, and its not even close to sounding this loud. very very misleading and not worth the money

Dylan09/30/2014, 10:17 PM

Gave Spencer a call and placed the order for this exhaust. I took months to choose an exhaust that sounded like something I would like and let me tell you this is it!

Install was a breeze with all the included hardware and zero issues.

By the way Corksport, my friend helping me install the exhaust was so amazed by the quality of the system and the sound that he'd buy a cat-back from you guys for his 2012 ralliart if you made one. And he's picky!

Jason Adcock09/30/2014, 10:17 PM

Had this on the car for about a month now. Beautiful product, it's a shame placing this under the car where no one can see it. Noise is not bad at all when just cruising (which I like since this car is my DD) but when you hammer it down it growls and has a great throaty sound. This with the catless racepipe adds great low end torque. And as always great customer service from Corksport.

Andrew09/30/2014, 10:16 PM

WOW! The car sounds amazing! I coupled the Cat Back exhaust with the DP w/ high flow cat...such a great sounding exhaust. The CBE is an easy install with the great instructions supplied by CS. I added the CS urethane exhaust hangers...I was afraid the stock hangers would not be able to keep the exhaust from rattling. I am very impressed with the exhaust. I agree with Andrew...it's a shame such a great looking product is hidden under the car!

Will this fit a '10 Mazda 3 2.5L? Just from the pictures between the 2, the CBE looks identical. I have the option to pick one up from a friend and would think the CBE is the same for both, I only know the ABE has been tested.

I Purchased the Axle Back Section a few years back and it was non-resonated/non-muffled at the time, i currently still have only the OEM Mid-pipe with the resonator in there. I have a suggestion for you guys at corksport, if you welded in a wireless controlled butterfly Valve to the driver side exhaust outlet then this can be marketed as a Valved exhaust system and would also be a great addition to your current lineup adding more robust exhaust system choices. Please let me know if this interests you!
