Performance, Reliability, and Sound for your build…this is the exhaust manifold for your Mazdaspeed 3. You are looking at the only performance exhaust manifold that can fit 3 different turbo flange options: Stock Mazda Flange, T3 Flange, and Precision V-Band. This modular design allows you to choose your flange style and change it later without replacing the entire manifold. Cast from 304SS, there are no welded flanges or connections that are prone to cracking and each flange surface is precision machined for flatness. Whether you are stock turbo or looking for the most powerful stock flange turbo, the CST6, this manifold supported 685 Whp with ease and don’t forget the specifically designed dumptube that makes life easy for you.


2006-2013 Mazdaspeed Big Turbo Manifold

MS3 Cat Exhaust Manifold

Power:

30-40whp gains over an XS Power V3 and faster spooling. This is the result of a well designed, high flow exhaust manifold. Power over the entire curve results in better drive ability and faster times at the track.


MPS3 Turbo Manifold

CAD Designed:

Each component is CAD designed and validated on car for fitment and performance. Three components: the manifold, flange elbow, and dumptube come together to create the most complete exhaust manifold kit available.


MPS3 Turbo Manifold

Runner Design:

The CorkSport exhaust manifold utilizes 1.59 inch inner diameter runner for superior high power flow and smooth radius bends to reduce exhaust gas velocity losses vs the sharp bends and 1.41 inch runners found on the XS Power V3 and similar tubular exhaust manifolds. Exhaust gas velocity and smooth flow are the keys to an efficient and powerful exhaust manifold design. Utilizing casting vs tubular allows us to optimize both of these critical aspects.


2007-2013 Mazdaspeed 3 Turbo Manifold

High Flow:

Through a combination of computer aided flow simulations and flow bench testing, the CorkSport Exhaust Manifold was optimized to increase peak flow capacity and thus performance. Flow bench testing at 28 inches of H2O showed an average CFM flow improvement of 45% over OEM and 33% over XS Power V3.

Bullet Collector:

A shallow 16 degree angle collector with a defined “bullet” point was utilized to increase flow efficiency into the turbine for improved peak flow and power. Paired with individual runner lengths that vary from 10.50 to 12.40 inches, the CorkSport manifold improves flow balance while maintaining the unique Mazdaspeed exhaust note.


Mazdaspeed 6 Big Turbo Exhaust Manifold

Flange Selection:

The only exhaust manifold available today that lets you choose your flange style and change it later for minimal cost and headache. With a modular flange design you can choose a Stock, T3, or PTE V-Band flange today and if you change your build in the future you only need the new flange elbow, not the whole manifold. Designed for standard 44mm V-Band External Wastegates.


Speed3 EWG Dump Tube

Dumptube:

With the unique location of the EWG we developed a custom fit 2-piece dumptube that makes installation easy. You can add this optional dumptube and avoid the high cost and time to have a custom dumptube fabricated. Designed to work with most typical downpipe and turbo setups.


Cast Mazdaspeed Exhaust Manifold

Manufacturing:

With the high heat and pressure demands put on the exhaust manifold; material and strength are critical. The CorkSport manifold is investment cast from 304 stainless steel with 0.50in (13mm) thick flanges and 0.20in (5mm) thick runner walls. This manifold is beefy so it can handle the high power high heat reliably.

Will be buying this for a CX-7. Have the exhaust manifold covers been tested with these? I'm in Cali and need to hide the manifold as much as possible from the smog cops.

From the graph, it looks like there was a six percent gain. I have a CS-FMIC, CS-TIPSRI, CST4, can a tune. Would I be looking at about the same percentage gain?
