im trying to replace the gaskets for the axle back where the 2 pieces connect and the other gasket atthe end. what size gasket does it take?
80mm Flange gasket, give us a call anytime to order replacement parts.We will do our best to facilitate 360 260 2675
Will this axle back exhaust fit my Mazda 3 S 2.5L Sedan?
It will not fit, it is for the Mazdaspeed3 only
>100mm Stainless Steel tips What is the inside diameter?
Inside diameter would be around 95mm
I have a resonator delete currently, will that effect the fitment of the exhaust?
If the flange is in the same location as the OEM exhaust, no.
Can you get this axle back resonated? Like the one on your cat back system.
Call our sales team, we might be able to work out something. 1-360-260-2675
can i purchase the muffler delete pipe portion? (i have the corksport cat back exhaust already)
Do I need to have the HPFP internals installed for this exhaust if I am running the CS SRI now?
For this exhaust no. Only once the downpipe is installed or you have started tuning the car.
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?
The full turbo back will be 80mm all the way through. The axle back will fit to both.
Will there be development on a similar axle-back, but single instead of dual outlet?
Unfortunately, i do not see us producing that.
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)?
We can make sure that you get proper hardware for it.
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.
Not 100% sure if it will fit, but there will be more room under the car once our exhaust is installed. If it fits with stock exhaust, then it should fit with ours.
If i didnt get the mid pipe im i going to hear any sound difference?
You will definitely notice a difference. You car will be louder and have a lower growl to it.
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.
You need to use the flat gasket we provide or you will have an exhaust leak.
Would this fit my exhaust system if it's all Stock?
Yes it will!
I'm fully stock at the exhaust. Would I be running into exhaust leak trouble. Would it fit good with it or do I need to alter stuff
Nope, it is direct fitment!
So this axle back system will fit the bumper tip cut outs on a mazda 3 gt?
We have never tried one. Based on what we have seen on the forums the cutouts are in the correct location.
Will this axle back fit my 2011 2.5L Mazda3 HB?
It was designed for the Mazdaspeed 3, we have not tested it on a regular MZ3 hatchback.
I bought one for a 2.5 Mazda 3 cause I was making a full exhaust and couldn’t make the y pipe. They called asking if I new it wouldn’t fit and I tried before taking out the old rotted exhaust and it will fit.

This exhaust sounds awesome. Fit great and the quality is just breath taking. Its loud but has a great sound quality.

Since the axle back portion of the MS3 fits the MZ3 2.5L, would this fit as well?
CorkSport Reply:It could fit the Mazda 3 but it would be really loud.

Love the look and sound of this on my 2010, I do have a little trouble with keeping the tips lined up properly though. They seem to keep shifting to the left side of the car. Has this been reported by anyone else? I do have the CS poly hangers although I doubt that would be a factor. I've been meaning to take it off again and rebolt to see if I can keep it straight.
CorkSport Reply: Check the flange where the axle back connects to the factory exhaust and make sure it is squared up.

Is it safe to run on an otherwise stock car? I've heard people say you need a fuel pump upgrade or something like supporting mods (intake) to run this. Can I run JUST the axle back on a stock MS3 without Access Port or anything?
CorkSport Reply:You can run the axle back exhaust with no other modifications required.

A police officer actually pulled me over to say the exhaust sounds Great!

Which one would be more beneficial the axleback or catback?
CorkSport Reply:The Cat back is made for more power gains.

What a great product, the welds are perfect and everything fits exactly. I installed the exhaust in about 20 min and was off driving, It Sounds amazing and compared to having a small straight pipe out the back this gives more low end Tq. Great Product Corksport! keep us the amazing work! I have video on youtube of the car, search usr name Greyskyy151

CorkSport Reply: The exhaust includes everything needed for installation.
