Get maximum turbo performance and dramatically increase torque with the Mazdaspeed 3 Power Series Downpipe. The CorkSport downpipe has been expertly designed to replace the restrictive element in the Mazdaspeed 3 stock downpipe. Mandrel bent piping is used to create smooth exhaust flow for dramatic increases in power. For lasting corrosion resistance and reduced heat transfer to the engine bay, the CorkSport MS3 downpipe uses polished 3 inch 304 stainless steel and features TIG welds that offer superior arc and weld puddle control for a cleaner appearance and precise weld bead control.

Our all new catted-downpipe option includes two O2 bungs and includes a high-flow metallic flexible catalytic converter and the CorkSport Power Series Racepipe for additional horsepower and torque without running the risk of an unwanted check engine light.

The Catted downpipe option is configured with a factory style donut exhaust available in two diameters. A 65mm fitment to the stock exhaust or 80mm fitment to accommodate your CorkSport or other aftermarket cat-back exhaust.

The CorkSport Advantage:

  • Minimal exhaust flow restriction
  • Polished 3” 304 stainless steel piping for corrosion resistance and reduced heat transfer
  • Unique Divorced Waste-gate Design: Reduces exhaust flow disturbances related to waste-gate operation and boost spikes
  • Mandrel bent for a smooth exhaust flow and solid power increases
  • TIG welds for a stronger more seamless connection
  • Genuine CorkSport Look: Stylish etched stainless steel CorkSport logo plate
  • Gains in power up to 21 WHP when installed on otherwise stock Mazdaspeed
  • CorkSport Service and Support: Receive a 2 year warranty, full color installation instructions, all of the needed installation hardware, and knowledgeable telephone installation support

Catted Downpipe Option*:

  • High Flow Cat: Includes a high-flow metallic flexible catalytic converter and CorkSport Power Series Racepipe. Get added horsepower and torque without running the risk of an unwanted check engine light
  • Factory style donut gasket: Available in a 65mm fitment for the stock exhaust and 80mm fitment to accomodate your CorkSport or other aftermarket cat-back exhaust
  • *Installation of the CorkSport Downpipe with High-Flow Cat replaces the downpipe and racepipe.

    *Installation of the downpipe without the high-flow catalyst option will activate CEL on 2010+ models and is not legal for street use.
    *Catted Downpipe Option is not available to California residents

Awesome dp. Just be ready for a lot of cussing getting the stock dp out. What a pain in the a$$.. installing the corksport dp was a cinch after that. Took me half a day just to pull the stock dp. Took about 1 hour to install cs dp.
awesome product... the install is annoying but get a buddy and the time really flies by... only issue i had was it seemed the instruction weren't all there, theres a change between the online one and the one mailed to me so i had to switch between the too

overall though, super happy with the exhaust, now just need to finish my bolt ons and get retuned and i'll be more than happy with my red beast
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!
Hey corksport this might be a dumb question but something in the description make it sound like the race pipe comes with the down pipe if I get the downpipe without the cat, is that right or do I need to but the race pipe separate? And you guys got 5 stars because I love the Intake and the instructions were SUPER SIMPLE!
Don't be afraid of this install...I had read how terrible it was, but it wasn't TOO terrible. It's definitely an install that requires a little patience, but it didn't take as long as I expected. Spencer at CS told me the hardest part was taking the stock DP out...he was correct. The CS DP goes in so easy...I used crow's feet with my torque wrench to tighten the bottom bolts, but other than that, I followed CS's great instructions.
If I have your Corksport race pipe, does the high flow cat option get rid of the race pipe or does it hook right up?
Just installed this along with the CBE. I love it. It's like my car was sleeping and this came along and slapped it in the face and told it to get moving.
Hey corksport, I would like to install the catted down-pipe on my MS3. I understand I need to upgrade the fuel pump internals with this pipe but I don't have know of any tuning shops in my area. Im in chester county Pa. Any recommendations? Also what intake would you recommend that I could use all year round including winter? Thank you!!!
Hey I was wondering if I would need the 60mm or the 80mm I have a m2 performance test pipe with hks hi-power cat back. Can't wait to get order this and hpfp internals from you guys. Great work.
i have a question is it worth spending $600 for the dp or just $150 for the racepipe performance wise how much more do u get with dp
Does buying just the downpipe replace your cat? Or does the race pipe replace the cat?
If i have a stock exhaust and a 65mm race pipe from Corksport, will the catless downpipe fit my setup? It's indicated that it only comes in 3"...
Hey I have the corksport cutback 80mm will the high flow car bolt on directly to the exhaust?
so this is not legal in california??!
So for people in Cali you can't purchase the catted down pipe? Any way to get rid of the CEL for those without the cat?
Which size connector for future OBX ehaust after first using stock exhaust?
I want to purchase the downpipe with the high flow cat however, what is the OEM fitment size for the second gen mazdaspeed3? 65mm or 80mm?
I currently have stock exhaust and will eventually get CSCB. If I order the 65mm now, will I be able to switch it to the 80mm? I hear quite a few comment on speeders just getting the DP and loving the sound and performance. Any suggestions?
I have an '09 MS3 with your SRI... Warranty is up so time for the toys...Is there a specific fuel pump upgrade you recommend running with the downpipe? Also as long as I get the catted model will I be ok running this in NY?

CorkSport Reply:We will have our pump internals available on Feb 7th. We are not sure on the local laws for emissions, I would talk to your local emissions tester.
Does this car have the old forge BPV with the nina sword sound?

CorkSport Reply:Yes it does.

Hey CorkSport, I currently have a MagnaFlow Cat-Back exhausted system installed (3inch tubing). Just wanted to make sure the catted downpipe option will align/fit with the magnaflow and would I need a 65 or 80 connection?

CorkSport Reply:The Magnaflow exhaust necks down to the stock size donut so you will want our stock fitment racepipe.
Man Big Thanks to My Hommie G CornDizzle, You know why! Greatly appreciate it bro I'm actually hanging the letter on the wall! After Tonight It's Big Boy Power from here on out!!!

I'll point pics of before and after, and video of stock take off vs CS DP. CS team yall make me feel safe using yalls products because I know I cant trust that theyre made right and will keep my $30,000 investment going strong!!!

Will I be ok installing a downpipe+high-flow cat on a 2010+ mazdaspeed3 and leave all other exhaust parts oem?

CorkSport Reply: An upgraded fuel pump would need to be installed. A tune is a good idea as well.
I just got my down pipe as a b-day gift ;-) lucky me lol!, I spent an hour or so on Friday doing installation of course I did not finish because it got dark, then finish everything up next day. Starting from instruction on how to instal to the product itself, everything was perfect. The final result is just wow! Sound wise, it got a deeper, robust, louder but not too loud tone, which by the way I love it(still stock exhaust on my car). Performance wise, the kick you get from the higher torque is a huge difference, the only bad thing is I cannot hit it too much because I am waiting for my HPFP(high pressure fuel pump) internals in order for me to hit my car as hard as possible. Main points so far, installation is a pain in the but but Corksport make it as painless as possible with their great instructions and awesome product quality which by the way, CS down pipe has better fitment than stock. If you get down pipe please get HPFP since is a must or you will blow up engine. Corksport, what an amazing job you did. Extremely happy with product, result, customer service, etc.
I will say this product was a breeze to install. Taking the old down pipe off was not as easy. I installed this with the cat back and catted down. So far no check engine light so thats awesome hope it stays that way. The oxygen sensor socket is a must for this install as well with a lot of patience. But in the end well worth it. Love the sound with the cat back. I will post back later after i throughly test it. thanks CS.
Hey CS so will Autotech Hi-Volume Fuel Pump Upgrade Kit support my CS TBE?

CorkSport Reply:yes it will.

Hey CS I just got the catted turbo back exhaust from you guys and I was wondering if it will hurt my fuel pump or internals. can I leave those stock while im runnin the turboback exhaust plus the CS stage two SRI?

CorkSport Reply:We recommend upgrading your pump with the TBE exhaust. Please be careful until you get them.
They are so polished & shiny; artwork! More power than I expected! Sounds like a mature roar, not too loud, just loud enough. Now for my Stratified Etune!
What DP can i get for California legal use?

CorkSport Reply:No downpipes are legal in California.
I only have one question regarding the downpipe for the speed3, i am planning to go catless so i would need to buy the racepipe separately, but in the options for that it has two options for the stock exhaust flange and the 80mm one. i am also planning on keeping my stock catback so would i have to choose the 65 or 80? i am thinking i would need to choose 65 because i plan to retain the stock cbe but if i choose that would it fit on the downpipe ?

CorkSport Reply:Choose the 65 option. It will work with the CorkSport downpipe or the stock one.
I just installed my cat less down pipe today and what a difference it makes!! As long as you spray your studs and o2 sensors they will come out with ease. Now my corksport full turbo back exhaust is complete and sounds great.
AI have a 2007 Mazdaspeed3 with a CS turbo inlet pipe, Cobb ap tune and catback system, what is the recommended fuel parts to keep the car running smoothly?

CorkSport Reply:Upgrade the high pressure fuel pump internals.
Hey there CS iv got a question and possible alternative to to my problem help me on this if you can offer me some insight or help. Im only really able to buy the dp without the upgraded cat con. So since that's my problem i was looking at the CS race pipe and add a cat to that and purchase it when i can then install, now if I did this would that keep the CEL off? And to shorten this up could y'all give me some information on staying CEL free while i work with in my budget?

CorkSport Reply:Give us a call 360-260-2675
I want to do some turbo back mods but Im in California. Are there any downpipes, catted that can be sent or used from corksport that my 13 ms3 can run?

CorkSport Reply:Due to the emissions regulations in California any performance catalyst is deemed illegal so we are not allowed to sell them there.
will this work with my 2007 mazda 3 hatchback? not mazdaspeed 3. Also have aftermarket Borla cat back exhaust

CorkSport Reply:No it will not, it is only for the turbo models.
Beautifully made pipe, much more compact than the stock DP, install was a sinch, removal of stock DP was not as easy as I thought, but it got done.
I have replaced almost my entire exhaust with the corksports catback system and it sounds amazing! the last thing I need is the down pipe but I don't want to run any cats. Do you guys know if the cobb ap will automatically tune out the cel, so I don't have to run the cat? this is probably a question for cobb so if you don't know it's cool. I still am extremely happy with the parts I have bought.

CorkSport Reply:The COBB Ap does not autotune your car. We recommend speaking with a tuner local to you or one of the E-tuners on the forums.
If I ordered this with the exhaust system to go with it and short ram intake, would I need a Tune? If so what can I get away with without having the ECU tuned...Trying to not void warrenty

CorkSport Reply:You will want a HPFP upgrade at a minimum with the installation of a downpipe, a tune is a very good idea too.
This thing looked awesome when I pulled it out of the box. Install wasn't that bad did it on jackstands in my friends basement. Thanks again for an awesome product
I have a question...beside the catless giving u a cel what other potential problems can this dp cause.....just asking...I want to go catless

CorkSport Reply:An upgraded HPFP is a good idea as well as a tune.
Love the sound i got with stock muffler and great power gains intake dp cobb tune hpfp and i keep up with stage 2 stis!!!!!!!!!! ty corksport

Am I gonna be running safe, if I get the system first (install it) and get the AP and HPFP after?

CorkSport Reply:We recommend the installation pump internals with the downpipe.
I am really interested in buying the whole CS TBE system, so before i do that, Do i need AP right away after installing TBE and upgrade my fuel internals?

CorkSport Reply: With the installation of the TBE you will need the HPFP internals at a minimum. We recommend a re-flash or the COBB AP as well.
Can the 65mm be replaced with an 80mm, once a person upgrades to an aftermarket exhaust after having a stock one? Or would a whole new DP need to be purchased?

CorkSport Reply:The catted downpipes are welded units so you would need to replace the whole downpipe to go with the 80mm outlet.
Absolutely bad ass! Install instructions were good, but I would HIGHLY recommend using a lift. I couldn't imagine how terrible that install would have been on my back. Use plenty of PB Blaster and be gentle with the O2 sensors. My car ran like junk until I upgraded my fuel pump, so I would recommend getting your CDFP internals put in first. With the fuel pump upgraded, it's a brand new car!! Absolutely amazing sound and super smooth pull through the entire RPM range. Corksport always delivers top notch products and this part is no different.
So if I live in California I can't get the downpipe right? But the catback exhaust shouldn't be a problem with the California regulations though? Thanks

>>CorkSport Reply: Removing catalysts is something which is not legal anywhere. Choosing to do so is up to the owner of the vehicle.
The product was a success and will recommend it to everyone that is considering one. I got the catted race pipe option and love sound and power it puts out.The ms311 is quicker and ready for more ammunition added to its arsenal. Only thing difficult was installation.
I decided to go with a catless downpipe and catless racepipe, to compliment the CBE I'd purchased earlier last year. HUGE difference in sound (and performance, after the tune). In fact, the only complaint I have is less with the product and more with attention to detail. Based on the instructions there should have been two long bolts (to mate the RP and rear exhaust), and two shorter bolts (to mate the RP to the DP), and I was sent 4 of the long bolts instead. (Shoulder of the long bolt goes all the way through the hole, which doesn't allow for any sort of tightening).

Aside from a little on-the-fly fabrication, the parts are AMAZING?!
Just installed this past saturday and am loving every minute of it. It sounds great with the CorkSport Race Pipe and CorkSport Axle Back exhaust.
Installed this baby catless with the racepipe and the sound is incredible at WOT!!!!!! idles deep like a champ and screams and im pushed back into my seat!!!!! Best upgrade by far!!! Gained about 20WHP when flashed to Stage 2OTS :) but it feels like so much more. Holding high in the 18s for PSI and I peak at 19.4 This is a completely new car now!!!!!!! Thank you CorkSport
Wow! Install was a touch of a PITA, but managed with help. I love the divorced waste gate. I was a little worried about the noise. Gains are excellent, turbo spools faster, and the noise is nifty. Corksport delivers and excellent DP.
AMAZING product from Corksport and has created quite a buzz on all the forums. This Down Pipe awakens the 2.3 turbo charged engine. This Down Pipe along with the Corksport Race Pipe and Cat-Back system are just what the turbo ordered! Finally a quality product backed by a company who stands behind its products and you have the perfect combination!!!
I just installed the highflow catted version of the Corksport Downpipe on my 2010 Mazdaspeed 3. The first thing you notice is how smooth the car feels along the whole RPM range. Second give it some gas and in the lower gears there is a whole lot more pull and it gives you a smooth delivery of power and faster turbo spool up. I am happy with the pipe so far!! I recomend Corksport to anyone with Mazdas! Watch out for tha last bolt on the old pipe it's a killer

man this thing look bad ass. It's easy to install. The hard part was getting the stock one off. Just like everthing corksprot make it's great. thanks for helping me make my car faster
Awesome DP! The Unique Divorced Waste-gate Design is one of a kind, no other design out there is quite this awesome. Cant wait to get this beast installed. Thanks Corksport!
Picked up 30-50 ft pound of torque on Dynodynamics dyno below 2500rpm on my fully bolted '08 with Cobb Acessport Stage 2 with 93 octane tune. 316 ft lb at the wheels--and Dynodynamics reads low! Just nuts--and you're nuts if you don't get one.
Great fit and finish. Combined with my other Corksport parts (Intake, TIP, and TMIC) the car is quick. I am at the limit of the stock turbo with my Stage 2 tune and these parts. As always, I am impressed and will recommend to anyone in the market for a downpipe.
