Conclusion from our Test:
Starting off from where we left off on our 2011 STi sedan.
After finishing product testing on the Tomei Arms M7960 it was time to test out another turbo. We chose to go with the brand new state of the art GTX billet wheel technology from Garrett, and use the ATP GTX3076R Stock location turbo.

The goal for this stage of the build was to really maximize and fully utilize the stock components along with having a very fun and efficient car that was realistic for someone to drive on the street, track or drag. This turbo would be the perfect match for anyone who is trying to get the most out of a stock motor, have quick response, and have one wicked car.

To put everything out on the table, we really feel as though we were maximizing several key components on the car, the motor, and clutch is still 100% stock. The Process West intercooler was getting close to its peak efficiency, the turbo was running at 25Psi, and given the octane of fuel we were getting close to the peak stability point of both fuels that where being used. The amazing thing is just how fast this turbo spools, looking at both race and pump gas you can see that compared to the stock VF48 the increase in lag is quite minimal for the huge gain in performance. Also given the altitude of 4200ft this turbo, compared to sea level it would be able to easily produce over 400WHP at similar conditions due to the increased air density.

The power delivery on the vehicle is very smooth and predictable, given the high efficiency TMIC the lag is kept to a minimal and the throttle is very responsive. The vehicle very easy to drive, quick, fun, and overall a simple build utilizing quality bolt on components from proven manufactures ensuring that everything is running at a safe and optimal level.

Huge thanks to the following manufacturers:

Tomei Expreme Ti Titanium Catback Exhaust Subaru WRX / STI 2002-2007 is proud to introduce the 
Tomei EXpreme 100% full Titanium Catback Exhaust for Subaru WRX / STI 2002-2007

$1035.50 Shipped in the Lower 48 States!

High quality production, for true competition use without compromise. Only the best Titanium grade materials are used. From the special racing layout design, made as straight as possible, to the high flow silencer. Tomei has poured all the knowledge and racing experience into this great system.

The Tomei EXpreme Ti weights in at an astonishing 10.4kg (22.93 lbs) less then stock!

Key Design Elements:

Racing Layout-In order to achieve the best performance possible from this product. Tomei have designed the layout of this exhaust system to be as straight as possible. By minimizing bends and the angle of the bends, we were able to maximize the exhaust gas flow efficiency.

3 Section Pipe Assembly-The conventional style flange is not used to help reduce weight even further. The use of the springs and clamps eliminates the need for gaskets as well.

High Durable Glass Wool -The long fiber wool threads were adopted for the silencer. This type has proven to last longer than the traditional fiberglass materials even over a longer period of time with extensive high temperature exposure both at high and low pressures.

Muffler-Made from Titanium material to Φ115mm diameter and 1mm thick piping. Straight cut designed and finished for race use. Finished off with the EXPREME Ti logo laser etched on the tip with the Titanium gradation blue colours.

Muffler Case-This part is made from Titanium with the pipe size of φ152 and 1mm thickness. The oversized shell design optimizes exhaust gas flow which helps with power gains. Then with the embossed Tomei logo and beautiful heat gradation colouring gives it the finishing touch that you’d expect.

Muffler Mesh-Made entirely from Titanium of 1mm thickness and with the open slot ratio of 32.6%. With the combination of light weight Titanium material, the high flow design delivers a really nice racing exhaust sound.

Main Pipe -Made entirely of Φ80mm and 1mm thickness titanium piping. These pipes are designed with minimal bends and weight for optimum flow characteristics. True race purpose design.

Flange-Made from 6mm titanium plate for weight reduction and the 6mm prevents cracking and distortions.

Cobb Tuning Mazda Speed 3 Downpipe Finally Here!

COBB 3” Downpipe for MazdaSpeed3

COBB Tuning announces the immediate availability of the COBB 3” Downpipe for the 2007-2008 MazdaSpeed 3, which is a study in engineering design and artistic execution. The COBB 3” Downpipe replaces a very restrictive element in the Mazdaspeed3 exhaust system. Considerable effort was spent designing a flow path with the fewest number of direction changes and minimal degrees of bend in order to eliminate restrictions. This beautifully fabricated downpipe delivers significantly improved exhaust flow, resulting in faster turbo response time and power gains across the entire rev range, while still protecting the environment with its highly efficient custom catalytic converter.

The engineering that went into the COBB 3” Downpipe started with the CAD designed investment-cast turbine outlet, made of 304 stainless steel for enduring corrosion resistance and reduced heat transfer to the engine bay. The shape of the outlet flange makes optimal use of the tight confines of the MS3’s engine bay, smoothly blending turbine outlet and wastegate gases. The outlet flange is configured with two O2 sensor bungs; one to accommodate the stock O2 sensor and another with a pre-installed plug that can be removed to allow an aftermarket wideband O2 sensor or datalogging device with easy engine bay access. A custom spun metal substrate high flow catalytic converter comes next. This one piece 400 grade stainless steel cat has a much higher flow rate and longer lifespan compared to ceramic or “brick” style cats. It also reaches operating temperature faster than other style cats for cleaner cold-start emissions. A third O2 sensor bung is located immediately after the cat to be used by the second OEM O2 sensor.

The stainless steel flex section used in the COBB 3“ Downpipe is internally lined (unlike most flex sections) and provides smoother exhaust flow and much longer lifespan for the steel braiding. The placement of this flex section in the factory location (before the first exhaust hangers) is critical in absorbing engine movement and eliminating damaging stresses that would otherwise be applied to the flange, cat, exhaust hangers and chassis. This increases the longevity of the downpipe as well as downstream exhaust components.

All tubing used in the fabrication of this downpipe is polished 304 stainless steel for increased corrosion resistance and a mirror-like finish. The 304 stainless steel hangers are cross-welded and well braced to eliminate a point of fatigue that is evident in other aftermarket downpipe designs. The end flange uses the stock donut gasket and factory spring bolts to aid in flex, longevity and proper fitment. This provides an improved seal compared to other methods, as well as reduced noise. An additional benefit is that it makes
the COBB 3” Downpipe compatible with any cat-back exhaust that mates to the factory cat section. When researching downpipes for your MazdaSpeed3, consider COBB’s intensive engineering, quality of materials,
impeccable fabrication and all around versatility. The COBB 3” Downpipe is unmatched in the marketplace!

• Increased horsepower and torque
• CAD designed cast turbo outlet for maximum flow
• Minimal bends for less restriction
• 304 stainless steel throughout for corrosion resistance
• Custom spun metal substrate high flow cat
