Unleash the potential and growl from your car and take the step forward into more power! A full 80mm Turbo Back exhaust is now possible with CorkSport’s new Catted Turbo Downpipe for the 2021+ 4^th Gen Mazda3 Turbo (as well as CX30 & CX50 Turbo Models)!

Best Mazda Catted Downpipe Kit from CorkSport

Our downpipe uses a two-piece design, making installation easy without the need to wrestle with a single large, cumbersome pipe. The Downpipe starts with a high-flowing cast 304 Stainless Steel Bellmouth, then joins the 80mm mandrel-bent piping with a V-band connection for a leak-free seal.

We used 3D scan data from the OEM downpipe when designing our CS pipe, which means fitment is just like OEM and the CorkSport Downpipe will fit with any aftermarket Cat-back exhaust system, or even OEM!

A high-flow 300 cell Catalytic Convertor is utilized in our downpipe and has been tested to have no significant effect on power potential. A catless option is not available.

Do I Need A Tune?

Addressing the other elephant in the room: Tuning. We highly recommend getting a tune after installing the 80mm downpipe as there are very strict airflow limits in the stock tune that severely limit power. This will result in some mild stutters, surging, or “hiccups” at wide-open throttle. This does not do any damage as it is simply a very conservative safety limit for stock components.

With more flow-efficient parts (i.e upgraded intakes , Turbo Inlet Pipe, and exhaust systems), these limits are being reached much easier and the ECU will limit the power output of the engine. The vehicle will be drivable on the stock tune and still give you an aggressive growl out of your 2.5T!

Here you can see the power gains with a fully-bolted Mazda 3 Turbo that is tuned vs stock downpipe and stock tuning.

Your Mazda breathes just like you do. Maximizing the intake of air for your Mazdaspeed and freeing up the expulsion of used gasses (exhaust) will help your vehicle breath better, and go faster.

On the intake side of things, you can set yourself up with a Stage II Power Series Short Ram Intake which includes our mandrel bent turbo inlet pipe, custom designed MAF housing, and silicone coupler. This will free-up flow into the stock turbo and allow your Mazdaspeed to breath deeper. The average gains seen here are 10-15 hp.

For exhaling, you want your Mazdaspeed3 to expel all those used gasses as quick as possible. With the CorkSport turbo-back exhaust, you are reducing the back-pressure and allowing your Mazdaspeed to utilize the potential of its turbo. The kit comes with CorkSport’s full 80mm catback dual exhaust, racepipe, and downpipe. This setup will give the average MS3 owner 28-31 hp at the wheels.

For those of you on more of a budget, may I suggest just the Short Ram Intake and racepipe? For this smaller investment, you can get an increase of wheel hp in upper 20’s to lower 30’s.
