Get maximum turbo performance and dramatically increase torque with the Mazdaspeed 3 Power Series Downpipe. The CorkSport Mazdaspeed downpipe was expertly designed to replace the restrictive element in the Mazdaspeed 3 stock downpipe
Which would i need with the Ultimate Racing Catback exhaust, the 65mm or 80mm?
Does it require a tune if I run your high-flow cat? I have your stage II full intake and fuel pump internals.
It does not REQUIRE a tune, but we highly recommend getting a custom tune.
I'm looking to go stage 2. How much power will I lose by mounting this to stock exhaust instead of a full exhaust. I would be using the catted option
You will not lose any power. You should see a major gain with a downpipe installed.
Good morning CS. I have 2 questions. I currently have a Cobb SS 3" Catback installed on my Gen 2 MS3. Which DP do I need. The 65mm or the 80mm fitment. And second, do you currently have the one that I would need in stock? The last time I ordered a Catback and it was on back order for 3 months. Thanks guys.
The COBB catback necks down at the catalyst connection so you want the 65mm version. It will be ~3 weeks until we have more of the stock fitment racepipes ready to ship out.
I currently livehave the long catted downpipe on my 2008 gen. I just bought a 2010 gen2 can i use my old downpipe on my new car? Thanks again great part.
Yes you can.
Where do you get your ots maps for the accessport?
The only OTS maps we offer on our website located in the fuel pump internals section. We also only offer stage 2 maps, so you are required to have a downpipe to use those maps.
im interested in the down pipe for my ms3 but my only thing that is holding me back is if will it pass maryland emissions? i have looked around if anyone around had passed but never got a straight answer.
You are going to want to order a downpipe that has a high flow catalyst in order to pass emissions.
Would the non catted downpipe fit the 80mm if I soon bought the race pipe and mid pipe
The non-catted downpipe will fit the racepipe.
I'm getting the hpfp and I'm fully stock besides the ap and fuel pump. Well would I have to run a certain stage 1 map or do I go straight to the stage 2. Any map recommendations
Technically you would want to run a stage II tune with a downpipe, but you are stock intake as well. I would consider running a stage I tune until you can upgrade your intake.
Would my engine be okay with the dp of I didn't get the upgraded fuel pump
We don't recommend running an aftermarket down pipe without upgraded fuel pump internals.
How loud is the car/do you get drone on the highway when you have an intake, fuel pump, and the long down pipe installed? It is my understanding that the CBE would mostly change the loudness Thanks, Eric
What exhaust would you be using?
I would be using the stock cbe. Thanks, Eric
The exhaust would be louder overall in volume but the tone should stay the same and there shouldn't be much of an increase with droning.
Will this downpipe fit a GTX3582r?
It will not.
I'm interested in buying a log catted down pipe and I was wondering, will the 85mm one fit the 3" CPE cat back exhaust system?
We have not tested it with the CPE Catback, but you should be able to get it to work, it just might require some tweaking to prevent a leak. If the CPE flange is truly 80mm, then it will fit fine with our 80mm, if it is actually 65mm and then goes to 80mm then you will have more trouble.
Hey guys. On my accessport I am running a stage 1 93 tune. The map I chose from Cobb was from the corksport intake, TIP, and internals. Is there any map that would also support the down pipe to get the most out of it?
I would hit up the stage II maps under the model year of your speed and CorkSport intake at this link http://www.cobbtuning.com/Maps-Archives-s/70671.htm#/v/accessport/maps/mazda/mazdaspeed3/MS3-Map-Grid-Archives
I have a 2006 Mazda 3 will it still fit? Because I saw you guys had the full exhaust system but nothing separately for the 2006.
This will not fit a Mazda 3, it is only for the Mazdaspeed 3 since you would need a turbo to attach it to.
Does this downpipe line up to a gtx2867R turbo?
You can use our downpipe with a GTX2867r.
i getting the p0421 warm up catalyst efficiency below threshold any could be a bad cat?
Why don't you call us or email us so we can help you? The FAQ section is not a great place to try and troubleshoot an issue.
What size would I need to attach this to a Cobb exhaust?
The 65mm will work for sure, the 80mm should be able to work if the COBB CatBack uses an 80mm flange.
Does the short dp bolt to the first cat on the stock exhaust ?
The Short Downpipe replaces only the stock downpipe which has a single catalytic converter. It will bolt to the stock racepipe which has the second catalytic converter.
I have a 2013 speed3 and I have a ark dts catback exhaust and I was going to buy the catted down pipe and was wondering which flange size would fit. Thanks
The 65mm will work if you currently have the stock racepipe attached to the catback. The 80mm might work if the flange on the catback is an 80mm flange, but I am not familiar with the Ark DTS catback.
I bought the catted DP and hooked it up to the stock exhaust and used the factory donut... if i was to go to a 3 in cat back, do i just remove that donut gasket or do i need to buy an adapter?
If you purchase the 3" cat back it will bolt up fine to the catted downpipe you have. Going from a smaller downpipe/racepipe flange to a larger catback is usually not a problem.
Will this dp bolt to a gt3076 turbo? Says it needs a 3 "dp
We have several customers that run GT3076 turbos with our downpipe, so it would work fine.
Corksport, I have just finished my full Corksport turboback exhaust. Is there any danger to my car being that I do not yet have a Cobb accessport to monitor my engine? I already installed the Corksport fuel pump upgrade and my other mod is the Corksport SRI. I plan on getting the AP as soon as possible. Thanks!
With the pump upgrade you should be safe but to get the most from the parts get the accessport as soon as you can.
