Introducing the COBB Tuning Stainless Steel Catless Uppipe. These kits are made for the Subaru enthusiast looking to unlock power hidden within the vehicle’s stock exhaust manifold. This beautiful uppipe is built to last for many years by using top quality materials and outstanding craftsmanship.

The COBB Tuning Catless Uppipe is constructed of rugged, 14-gauge, 2-inch diameter polished stainless steel tubing to endure the intense exhaust gas temperatures these turbocharged engines put out. These Catless Uppipes are CNC mandrel bent, ensuring precise and consistent fitment, eliminating the need for a weak flexjoint section. The Catless Uppipe inlet diameter matches the inner diameter of the gasket to maximize flow to the turbo. The extra-thick flanges are cut from 1/2" 304 Stainless Steel to prevent warping and eliminate high pressure exhaust leaks. The five turbo-flange studs come pre-installed. This gorgeous Uppipe is built to last for many long years of service.

Awesome product!

This Cobb uppipe is very high quality and the fitment was spot on. I've heard horror stories with doing up pipe installs because the new one doesn't fit right but I had zero issues with fitment, it fit like a glove! Can hear more turbo spool and feel quicker spool with this installed. Thanks RSD for great service as usual!

Install isn't that bad just takes some time. All it takes is jacking the car up, and a second person helping makes it easier. I love the thick flanges, and the prescrewed bolts. Really nice looking, and great quality. Slides into place a lot better than I was expecting, and fits perfectly. No complaints at all.

Top notch quality, perfect fitment, much lighter than stock (even wrapped), worked well with AP and other existing mods. Highly recommended.

  • AnswerQ: 2011 sti tune?  Andrea 2 months ago

    Does this require a tune on a 2011 sti and if so are there any off the shelf maps on the accessport v3 to support this?

    • A: In most cases no, an uppipe does not always require tuning. If you have a wideband gauge it would be best to make sure after installation you are still operating within your tunes parameters.

  • AnswerQ: 2015 STI   tempemail55b250c3caae52af708b5a16 3 months ago

    Will this provide performance gains for an STI? I know the SIT is already Catless...

    • A: This will allow minor improvements, but for the work involved we usually recommend other parts before the uppipe. If you happen to be replacing the header and already have it removed the uppipe is a great addition but by itself not extremely beneficial.

  • AnswerQ: 2011 Subaru wrx  Alex1313 4 months ago

    Does my 2011 Subaru wrx have an egt sensor and will I have any problems using this pipe. Also it says catless does my stock upipe have one. Also will I have any problems over boosting. And lastly I'm a running a stage 2 will I need a pro tune

    • A: Your uppipe will not have an EGT sensor or cat. While you shouldnt have any overboosting issues, a custom tune is recommended to take advantage of the added airflow.

    • A: The 2011 WRX wont have a sensor in the uppipe from the factory because it is catless. A tune should not be required for this to be installed.

  • AnswerQ: 1993 Subaru Turbo Legacy  Subie22 4 months ago

    Hi there, Curious as to if this will work with a 1993 Subaru Turbo Legacy, VF-11 Stock turbo. I can fit 02 to 07 downpipes/exhaust but just curious as for the up pipe.

    • A: The uppipe should fit although we could not guarantee fitment without the manufacturer confirming. We do have an employee with a '91 who uses the standard uppipes and downpipes without a problem.

  • AnswerQ: 2009 Forester XT  mcphersonjohnr2420740 5 months ago

    Do I need to worry about an egt bung on the stock up pipe of my 2009 Forester XT

    • A: Your car shouldnt have an EGT Sensor on the uppipe.
