Features & Product Details

Add more power and performance to your vehicle with the COBB Tuning Catted J-pipe. This is the non-resonated version which means that you will obtain a more aggressive sound. The J-pipe is typically known as the downpipe, and it is a direct replacement of the factory restrictive J-pipe in your vehicle. The COBB unit combines larger piping diameter along with smooth bends which limit exhaust turbulence under acceleration. Not only do you get the benefit of increased horsepower and torque, but you get improved throttle response with reduced turbo lag.

This pipe is 3" in diameter, and will come implemented with a 200 cel catalytic converter to remain environmentally friendly. 

Gaskets, hardware, as well as an exhaust adapter are included to make this J-pipe ready for installation.

Note: Not compatible with CVT transmissions.

Nice pipe 8 months ago
5out of 5stars

Had some issue getting the water pump bracket back in due to how thick the metal is where you bolt it to the turbo. Other than that, amazing pipe & amazing welds. Cobb Ots stage 2 runs perfect

that top bolt... 2 years ago
5out of 5stars

Beautiful pipe, super fast ship. Install, that was tough. Everything went great till the top bolt next to the water pump. Bolt striped and then the torx head broke off when I tried to pull the stud. My factory gasket was shot. So make sure to buy a set of bolts and studs and a new gasket. once the factory pipe was out this went in super fast and paired with my N1 she sounds pretty dang good. revs fast, pops occasionally, and 20 plus lbs of boost is easy to get to.

  • Q: Cobb non resonated on tomei exhaust   Arexxx1 year ago

    So I’m planning on purchasing Cobb non resonated jpipe for my 17 wrx . I’m currently only running tomei catback . everything else stock . Will I need an etune for this or is there a ots map I can download to my ap that I can run?

      A:  You would need to also delete the 2nd boost restrictor pill, but you could run Cobb's Stage 2 OTS map with that setup.

  • Q: fitment  ccevo2 years ago

    Will this fit 2017 WRX premium with factory-upgraded STP (STI performance) exhaust option? I think the STP is catback. I don't know if the J-pipe hooks up to the mid-pipe or not, eh? Also, is there a catless version available?
    • 0 of 0 people found the following answer helpful

      A:  The STP cat back should bolt up just fine, unfortunately we do not sell cat-less products any longer.
