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 2015-2018 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.

- CNC Mandrel Bent Tubing
- TIG Welded
- Ready to Run with COBB OTS Maps


Cobb Fuel Rail Line Kit

The COBB Subaru Fuel Rail Line Kit is designed to be used along with the COBB Fuel Rail Kit. All lines are pre-assembled with double-swivel sport crimp style hose ends and ready for installation. Stainless reinforced PTFE line with black covering has a 3" minimum bend radius which allows for a straight forward installation when used as intended. With a 2500psi operating pressure and >10000psi burst pressure, these lines are incredibly robust.


Cobb Silicone turbo Inlet

Constructed of black 5-ply silicone, the COBB Turbo Inlet is a direct replacement for your 2008-2018 STI! The custom silicone construction of the COBB Turbo Inlet rejects high engine bay temperatures and keeps the intake air closer to ambient temperature. The steel wire reinforced design eliminates the issue of hose collapse that other inlet hoses suffer under vacuum at peak demand, yet allows adequate flex between the engine and the intake.

The COBB inlet pipe is quite a bit bigger and longer than the standard inlet pipe. It is designed this way for a variety of different turbocharger and intake setups. Trim for best fitment within your needs.


3" Downpipe

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.

Subaru SF Intake System

Increased Power

The C.A.R.B certified (2010+ pending) COBB Tuning SF Intake removes a pre-turbo restriction in the stock intake system. The SF Intake intake system utilizes several unique features in an effort to maintain optimal flow for performance while minimizing turbulence that can cause engine management problems. From a custom conical cloth air-filter element, a CFD-designed velocity stack leads to an unique air flow straightener grid designed to smooth the incoming air flow as it passes the Mass Air Flow sensor for precise readings. The intake utilizes a one piece design constructed from a high temperature plastic composite, saving weight and reducing heat transfer.

Increased Induction Sound

Enjoy the increased snarl from your engine and hear the turbo spool more clearly with the addition of the COBB Tuning SF Intake system. Turbocharger induction noise and bypass valve venting sound is much more audible using this intake system.

Easy to Install

The COBB Tuning SF Intake was designed to be easy to install without having to modify your car. Installation requires no cutting or trimming of any components and can be completed with simple hand tools. Simply remove the stock airbox and bolt the SF intake into place in just minutes.

Calibrations

All aftermarket intakes for 08+ Subarus require tuning, regardless of manufacturer, in order to ensure the MAF sensor reads properly and the engine operates within safe parameters. COBB Tuning has you covered with Off-The-Shelf Maps for the Accessport, making it as easy as install, flash and go! Head over to the Subaru Accessport Map Database to view the full selection of SF Intake Maps for your vehicle.

Subaru SF Airbox

The SF Air Box adds the benefits of a cold air intake to the outstanding performance of the SF Intake. The factory inlet directs cold air from the front grill to the SF Airbox, which encloses the SF Intake. Hot engine bay air that robs horsepower is prevented from entering the intake system to provide consistent intake performance. This unique design also separates rainwater from the intake air, eliminating the water ingestion issues that plague in-fender cold air intakes. This intake airbox is constructed of 16 gauge aluminum, consisting of a one piece surround, directional lid, stainless steel hardware and all the necessary components for a seamless install with OEM quality fit and finish.

Features
  • 16 gauge aluminum construction
  • Uses factory snorkel to feed cold air to airbox
  • Benefits of CAI without water ingestion issues
  • Easy installation
  • OEM quality fit and finish
