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

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.

The exhaust uses 1 hanger on the muffler, 1 hanger on the mid pipe, and 1 hanger right before the muffler (this is the only one that is different on GC's vs GD's. It would be best to use all 3 hangers. However with some stiffer afternarmarket hangers this should not be to much of a problem as this system is so light.

When installing it, I couldnt believe how much lighter it was then the SS system I was pulling.

So installing this exhaust on a GC wouldn't be a problem?

I had actually suggested this exhaust to my buddy Phi who currently has it on his GD.

It is indeed very loud, probably one of the loudest exhausts you can buy, however it also doesn't play off that way either. If you've never owned a Titanium exhaust you'll never understand, but the tone and resonance of the metal is completely different than say SS.

Main reason why I had suggested this exhaust was because my friend wanted to purchase my older Trust PE-Ti-R catback but I had sold it with my car. This was the next best option and I love the way it sounds. Quality on the piece is amazing (Just like every other product Tomei puts out), the weight is close to none, and sound is so addicting you just don't want to stop driving. Even with the silencer it'll still be a loud piece. If anyone is local to the South Bay area and would like to hear it, me and my buddy can meet you up.

If you like the way the Blitz Nur-Spec R sounds but want a sound that's not as generic and has a more aggressive tone to it, the Tomei is it. Is it louder than the Blitz???...... I'd say they're on par but tone is different. the welds are beautiful, the noise is amazing, and the looks of the exhaust are breathtaking. Buy yours today, and never regret spending money on different exhaust, trying to find one to fall in love with. The Tomei Expreme Ti is it.
