3" Catback Exhaust
304 stainless steel is used throughout the exhaust construction. All components are meticulously TIG welded for outstanding appearance and strength. Four custom exhaust tips fill the factory bumper cut-outs perfectly, protruding just enough to show off the COBB logos etched into the top of each polished tip. Perfect fitment is achieved with either the Subaru factory downpipe or the COBB 3" SS Downpipe. The COBB 3" SS Cat-back Exhaust for the 2015-2016 Subaru WRX/STI is a triumph in design and execution. Install the COBB 3" SS Cat-back Exhaust on your WRX/STI and experience performance like no other.
This mandrel bent exhaust uses twin straight-through mufflers terminating in beautifully laser-etched 3.5" quad-tips to make your presence known in the way that only COBB Subaru exhausts can provide. The outstanding craftsmanship and attention to detail are evident in every aspect of this gorgeous cat-back.

The COBB Tuning downpipe begins with the CAD designed bellmouth that directs the air coming out of the turbo. The design permits the air to flow with very little turbulence to the single high flow catalytic converter. This metal substrate cat is highly efficient, allowing the exhaust to flow much easier than the factory unit ever would. The COBB downpipe, combined with our Accessport engine management, is one of the most easy installations for any enthusiast looking to unlock the true potential of their WRX. 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 smoothly blends the turbine outlet and wastegate gases. The outlet flange is configured with an O2 sensor bung to accommodate the stock O2 sensor. 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 second O2 sensor bung is located immediately after the cat to be used by the second OEM O2 sensor. All tubing used in the fabrication of this downpipe is 304 stainless steel for increased corrosion resistance. The end piping tapers down to a flange that 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.
The COBB Tuning turbo downpipe is one of the premier modifications most owners look to upgrade on their vehicle. By opening the diameter of exhaust flow coming out of the turbo, the downpipe unleash power where the stock restrictive unit lacks.

Precision cut stainless steel ensures that the heat shield can withstand years of abuse. The COBB logo is laser etched and can be clearly seen no matter how much heat is being deflected. A great addition to show cars and race cars alike!
The COBB Tuning stainless steel heat shield is in house designed and a replacement for the factory turbo heat shield found on most vehicles. A modification which goes hand in hand with an aftermarket downpipe install. A heat shield prevents the venting of heat caused from exhaust gas temperatures to vent into the engine bay there by reducing heat soak into key components that benefit from cooler ambient temperature, such as the intercooler.
