    3" Stainless Steel Bellmouth 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 our 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 waste gate 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.

    Features

    • CAD Designed Cast Turbo Outlet for Maximum Flow
    • 304 Stainless Steel for Corrosion Resistance
    • Custom Spun Metal Substrate High Flow Cat
    • Two O2 Bungs for Factory & Aftermarket Sensors

    Cobb 3" downpipe on my 2013 WRX

    Absolutely LOVE this downpipe!! I was stage 1 ( Cobb SF , invidia q300, Ecutek protune) with no intentions for stage 2 or downpipe. Well, that changed and I'm glad it did. Cobb's quality of products, MAP's quality of delivery and ease of ordering made it simple and fast. The downpipe paired with my catback sounds awesome with the EJ motor. I went stage 2 Ecutek protune and the horsepower increase is really noticable from stage 1 to 2. The turbo spool along with that EJ rumble is undeniable. I highly recommend this product, Cobb is the best in the business.

    Fast Delivery, great purchase

    Well made piece with perfect fitment. I do recommend buying new gaskets for peace of mind. Not a whole lot of sound difference overall. It sounds a bit more aggressive with slight drone. The catted downpipe means I am not inhaling exhaust fumes at stop lights. I'm sure my toddler appreciates this too. With a proper tune, this purchase brought my car to life. Better torque for daily driving. Harder pulls at high rpms when you want to let it fly. City mpg did take a dip for me by 2mpg, but highway milage did not change. This could always be contributed to my own driving habits.

    I highly recommend getting this pipe and getting it from MAP. Before this was sent I had a concern that was addressed professionally and immediately, which really gave me peace of mind.

    Don't hesitate, pull the trigger on this mod and finally love your Subaru.

    Perfect

    If you’re looking for a catted downpipe, this is it. You get what you pay for, folks. Fitment was spot on and installation was a breeze.

    Great sounding downpipe

    I've been running this downpipe for about three weeks now and this thing is loud. I love every second of it. I constantly find myself on the gas just to hear my car roar. I would def recommend this dp to anyone looking for more sound and a little more power.

    Perfect fitment

    Just installed this together with a Perrin heatshield. Everything went in smoothly. This bad boy tapers to stock diameter at the end which may be a turn off for those wanting the last oz of power. For me, I'm fine as long as it reduces a bit of noise (paired with a Tomei Extreme-Ti). I purchased the Grimmspeed downpipe to catback adapter when I installed the Tomei catback, so I just re-used it this time. Car is in the process of being tuned. Already i noticed the sound has gone up a notch. I can't imagine running full catless... the noise would be so obnoxiously loud!
