Tomei Expreme Ti Titanium Cat-Back Exhaust (Type-D Dual Exit), 2008-2021 WRX & 2011-2021 STi (Sedan)

This kit includes all the components necessary for installation including the bolts and nuts. Bolt Smooth Paste is also included to help prevent the bolts becoming seized under heat.
ORIGINAL TITANIUM MATERIAL
Made from Titanium material to 115mm 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 colors.
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.
SILENCER CASE- This part is made from Titanium with the pipe size of 152 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 coloring gives it the finishing touch that you'd expect.
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.
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.
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.
Titanium is known to be difficult to weld but with our experienced methods we are able to achieve the best results with strength, durability and quality in finish. With the use of the right equipment, attention to details to yield the best results you would expect.
The welding procedure is performed with the best temperature controlled conditions. This helps secure the added strength and clean consistency in the quality of the welds. This prevents any defects that would have been caused by dust, wind and humidity.
