This is exactly the sound I was looking for! I have a resonator delete along with this axel back and the sound is so deep and aggressive. The build quality is top notch. Hardest part was getting the two factory bolts off but other than that, the installation was a breeze.

Thought I reviewed this but I don't see my post. May be because I bought it back with the old CS website. Bought back in 2014 still loving this exhaust now. I have put about 10,000 miles on the exhaust with no problems at all. My only complaint was installation. I could not get it lined up and it it kept leaking, even with using recommended torque. I finally gave up and went for a drive, came back and re-tightened and it stopped leaking and hasn't since for 2+ years now. Great sound and a head turner. Wherever I pull up someone seems to say, "love the sound", "what kind of exhaust is that". People at the car wash asking you to rev the car. Not only does it sound great, I could tell after installing that the turbo spooled up with more ease due to better flow. May one day get the full exhaust but if your on a budget like I am. This is just what you need.

So i happened to come across a craigslist guy selling this very cheap, and beings that i only use corksport on my car i couldnt resist. Sorry cs for not buying new but youll be getting more of my money soon, trust me. The axle back is great. Fit and finish of it is perfect. Bolted up with ease. The tips fill the bumper nicely. I found with a little tweeking of the hangers it sits snug in the middle. I had to switch 2 of the hangers due to wear in order to get it to line up perfect. So the guy before me said he bought it from someone else as well which means this thing is a beast to be able to do that many miles and ownership changs and still look and function perfect. The sound is amazing. Nice deep tone. Tiny bit of drone but almost unnoticeable at highway speeds. IMHO this is the exhaust that should have come on our cars. Thanks for an awesome product.

Very happy overall with the sound and look of this. Have it paired up with a test pipe and sounds pretty deep. Has an awesome growl when in boost. Corksports customer service is also a1, thanks for the t shirt! Will definitely be ordering more things soon. Thanks again for a great product!

Wow! I don't know why I put off buying this for my 2011 Speed3. Has a nice rumble similar to a Subaru. Customer service was top notch and I will definitely be buying more things from Corksport. Keep up the great work guys!

Sounds great. However I am pretty disappointed as the drivers side tip sits far lower than the passenger side one, and the passenger side tip sits further towards the middle of the car. I spent 3 hours trying to adjust this, and was unsuccessful. It appears to me that the exhaust hanger on the drivers side is longer than it should be. I even went as far as to replace the rubber exhaust hangers with OEM hangers from Mazda just in case they were the issue. Also using the gaskets provided I wasn't able to seal all the leaks, and I was using a torque wrench set to the specified 35ft-lbs. I ended up putting some Permatex copper RTV to seal the leaks. Overall happy with the performance and acoustics, but disappointed with the appearance and install.

Waited a while for this exhaust, looks and sounds awesome for the price, especially if you have a resonator delete as well. My only problem with the exhaust is the gaskets that come with it. They were hard to get perfectly lined up so the exhaust didn't leak. After a few tries I got it so there were no leaks. After a few weeks I checked on the exhaust and both connection points are leaking at the bottom of the flange. Im going to have to replace the gaskets to eliminate the leaks. Other than that, the exhaust sounds and looks great.

Can you get this axle back resonated? Like the one on your cat back system.

I already have this axle-back and looking to upgrade to a full turbo-back. Will I get true 80mm piping throughout with a downpipe and midpipe upgrade, or does this axle-back fit to 65mm?

Will there be development on a similar axle-back, but single instead of dual outlet?

Asked by Michael | 08/10/2016, 01:40 PM | 1 answer(s)

I already ordered the axle-back and have it, but due to rust I now have to go full catback. If I order the mid-pipe only, does it come with the required hardware to connect the mid-pipe to the downpipe (where the spring bolts are located)?

Any idea if the axle-back exhaust will fit if using the Curt 11383 class I trailer hitch? Looks like potentially the hanger for the driver's side might interfere.

If i didnt get the mid pipe im i going to hear any sound difference?

Asked by Speed | 02/02/2016, 08:52 PM | 1 answer(s)

When installing cs axleback to stock midpipe, do i need to remove the donut gasket in the midpipe and replace with the flat gasket provided with cs axleback? I have a slight leak but im not sure if its from the flat gasket being misaligned or the stock donut gasket from the stock midpipe. Overall the axleback is great in every aspect other than the slight leak.
