Tomei Expreme Ti Full Titanium Dual Muffler for Subaru WRX/STi '11-'21

CLAMP BAND
This clamp design is much stronger than the conventional flange and bolt type. It secures the pipe in place and can keep an airtight fixture whilst still being able to cope with the high heat, the stress loads and the vibrations that it will endure. 

TAIL PIPE
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.

-SILENCER 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.

-PUNCHED 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.

-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.

CONNECTING SPRINGS
The pipes are connected together with the use of the hook and spring design. This allows the pipe with some movement to help absorb vibrations. The hook springs alone is sufficient enough to hold the pipes together. However you will get the best secured pipe joints when using the clamp band and the springs together.
