Read The BlogProduct Release! CorkSport 2010+ Mazdaspeed 3 Axle Back Exhaust

New Options! You can choose the optional non-resonated rear version of our cat back to take the sound level up a notch. We made this option available due to customer feedback from those wanting a turbo back that captures the Mazdaspeed 3's flat exhaust note.

The CorkSport exhaust features mandrel bent 80mm piping, a straight through high flow muffler for a smooth flow, increased power, and faster spool up. Corrosion-resistant T304 polished Stainless Steel construction with 100mm stainless steel tips ensures long life; stainless steel resonator packing means no worrying about burning out and rattling. As with all of our CorkSport exhausts, the Turbo Back exhaust is precision TIG welded, making for a solid connection, cleaner look, and powerful presence.

Thoroughly tested, this exhaust has peak power gains on the dyno with increases up to 50 wheel horsepower over stock with the needed supporting parts (Max Flow Fuel Pump, Intake and Accessport.)

For off-road & race use only
HPFP upgrade and tuning required for proper and safe operation.
A check engine light (CEL) will be illuminated on catless and some catted setups as a result of installation.
Only fits on turbochargers with OEM downpipe flange shape.
If you have a CS turbo and are running an EWG off the turbine housing, the wastegate will need to be moved to the turbine housing directly and a new dump tube used. CS part number GEN-6-575-17 is needed and it is available for purchase HERE.

I bought the CBE and Catted Downpipe.....lets just say theres nothing like a full Turbo back Exhaust from Corksport....absolutely love it

Todd Mallorey09/30/2014, 10:22 PM

WOW! The car sounds amazing! I coupled the Cat Back exhaust with the DP w/ high flow cat...such a great sounding exhaust. The CBE is an easy install with the great instructions supplied by CS. I added the CS urethane exhaust hangers...I was afraid the stock hangers would not be able to keep the exhaust from rattling. I am very impressed with the exhaust. I agree with Andrew...it's a shame such a great looking product is hidden under the car!

Does anyone have video in the sound difference between the resonated exhaust and non-resonated exhaust. I want to see how I would prefer to buy this exhaust.

I know it's possible to instal the Mazda 3 2.5 exhaust onto a Mazda 3 skyactiv, but is it possible to put this exact exhaust onto the skyactiv?

I'm thinking about ordering the Turbo fatback exhaust. But was wondering if that included the race pipe as well?

If I purchase the midsection w/o axle back, will the piping bolt right up the the stock gen 2 axle back?

Asked by Avery Benitez | 12/29/2015, 07:07 PM | 1 answer(s)

If I ordered the kit with only the midpipe section (no axle-back) would you guys offer the single-exit piece to finish the exhaust? I'm a fan of the lightweight aspect but didn't saw it wasn't an option.

Asked by Matt | 12/20/2015, 01:41 PM | 1 answer(s)

I just ordered the full turbo back exhaust. Can I run this with out the high flow full pump for a while until I can save up and install it, or do I need to do that before the install of the exhaust?

Hi, could you tell me if this turbo back exhaust is emissions legal in Ontario, Canada? Also, will I need to order a donut ring for this install or does this include everything needed?
