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

The CorkSport Advantage

CorkSport 80mm or 65mm Flange Choices

Fitment Choices: Pick the 65mm flange for stock fitment (it will also work with all aftermarket exhausts), or 80mm flange for the CorkSport Cat Back exhaust and true 3" piping. Either way, mandrel bent piping is used to create smooth exhaust flow for dramatic increases in power.

CorkSport Downpipe and Intake Dyno Chart

Improved Power: With just an intake installed you can gain up to 50 HP more by adding the long catted downpipe, or short downpipe and racepipe.

CorkSport Short Catless Downpipe

CorkSport Short Downpipe: Replaces just the downpipe section but not the racepipe for a cost effective solution that works with the stock racepipe, or aftermarket. For lasting corrosion resistance and reduced heat transfer to the engine bay, the CorkSport MS3 downpipe uses polished 3” 304 stainless steel and features TIG welds that offer superior arc and weld puddle control for a cleaner appearance and precise weld bead control

CorkSport Long Catted Downpipe Replaces the Downpipe and Racepipe Sections

The CorkSport Long Catted Downpipe: Replaces both the stock Downpipe and Racepipe sections. With two O2 bungs and an included high-flow metallic flexible catalytic converter the CorkSport Long Catted Downpipe can be run withouth risk of an unwanted check engine light, or overspool on the turbo due to lack of backpressure.

Recently had my car dynoed and talked to the guys about installing the catless DP, they mentioned the non-foulers to prevent the CEL, as I was reading you guys said to install a new high flow fuel pump, my car was running really rich when it was ran on the dyno, I know a tune will help fix the problem but being what it is would a new fuel pump be necessary after the instal of the DP?
For all of you worrying about a cel with the catless downpipe, go to your local hardware or autoparts store, but a set of 2 spark plug non-foulers, use a half inch drill bit to drill out one while leaving the other the way it is. Screw the drilled out non-fouler into the one you left be, then screw your o2 into it ajd install in your downpipe. This will keep you from throwing a code. Reason being, the second o2 is narrowband, and cannot have exhaust gas flowing freely over it. The non fouler has a small hole that only lets a small, steady flow of exhaust flow to it, just like as if it was in the cat. Its a 2 dollar fix and I guarantee it to work every time. 60k miles in my evo 9, 80k miles in my eclipse gsx, and 4k my ms3, all with this simple mod, and none have ever thrown a cel code.
Happy modding!
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
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.
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.
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.

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.

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!
