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.
