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.

Installed this axle back a month ago. Fitment was perfect. The sound is awesome. Getting a lot of compliments on the looks and the sound. Quality is excellent A+. Sound at idle is throatier and louder at full throttle. Am I please with this system? Of course , as with many other Corksport parts I purchased in the past. Now what's next?

Jean-Marc Savoie 06/03/2015, 07:07 AM

Excellent quality, finish, and fitment. Sound is awesome! Great system for the price! Quiet at cruising speed , but the beast is awakened at full throttle. Another great product from Corksport. 5 stars for sure .

Just wanted to say installed the axle back system on my 2012 MS3. Very impressed, the sound reminds me of an SRT4 with good exhaust. No offense to anyone. But not too loud but pretty deep. Also as a note make sure you have the gasket and flange lined up perfectly before torquing. Took 2 trys to get it working with no leaks. But great system, looks good too.

2nd of three parts I installed today. I would have given it five stars but I had to do some work to get rid of an exhaust leak at the axle flange. Went to my local muffler shop and picked up a couple gaskets to tighten up the connection and finally got rid of the leak around the top of the flange. NOW, it looks and sounds AWESOME. Just what I was looking for, a little louder than stock with a nice deep tone, but not to loud at highway speed. Nice work. Glad I stopped looking at all those you tube videos and just pulled the trigger. If you are looking for a nice upgrade to your looks and sound this is it. Great Job Corksport!!

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?

Do I need to have the HPFP internals installed for this exhaust if I am running the CS SRI now?

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

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.
