Front Pipe (J-pipe) with High Flow Catalytic Converter for your 2015 Subaru WRX. So you want to get more power from your WRX but you still want to keep a Catalytic Converter on your car? Look no further than the TurboXS Front Pipe with High Flow Cat.

The TurboXS Catted Front Pipe for your 2015 WRX is one of single best power adding modifications you can do and still keep the planet happy.

Turbochargers work best when there is large pressure and temperature differential across the turbine wheel. Having a large, free flowing downpipe is what give you that large pressure and temperature differential. The downpipe tapers to 3" towards the tail and even includes a pre-welded 02 sensor bung for installing an aftermarket wideband O2 sensors. OEM style doughnut gasket enhances flexibility, durability and sealing as opposed to lower quality flex joints.

Features include:

  • All 304 Stainless Steel Contruction
  • 3.5" at the turbocharger tapering to 3.0" at the exit to the catback exhaust
  • 12mm thick flanges
  • High Flow Catalytic Converter
  • Hardware includes: J-pipe to mid-pipe gasket, Mid-pipe to Catback, Turbo to J-pipe gasket NOT included. Factory gasket can be re-used.

  1. Great response

    By Twrex19 December 18, 2021

    The car is more responsive with this Jpipe and the sound is nice.

  2. Great J-Pipe

    By Matt January 9, 2021

    Great J-Pipe and the price made it even more attractive. The sound is amazing with an Invidia N1 Dual cat back. Nice deep sound, and not that loud when cruising around...but nice and loud when you really open it up. I don't really get any backfires / Pops...which I'm happy about. I can't comment on install since it was none at a professional shop. Would defiantly recommend!!

  3. 10/10 would recommend

    By Zachary March 14, 2020

    So, do yourself a favor and get the Grimmspeed OEM hardware kit for the studs that’ll back themselves out of the turbo and the 2.5” to 3” adaptor (if you’re using your factory mid-pipe) along with some PB Blast and you’ll be golden on the install. Just have some patience.

  4. Very good downpipe!

    By CHRISTIAN February 26, 2018

    I had 2 nuts seize on the turbo studs. That was a paaaaaain in the butt. But besides that, the rest of the installation was fairly easy. The only downside was that the front O2 sensor was a little far to plug in. So I had to unscrew the harness just to make it reach and then ziptie the wiring to the heat shield, at least until I get an O2 sensor with a longer cable. Besides the pains with installation, the car sounds amazing. I was going for sleeper sounds which this totally does the job. You can hear turbo spools but it's not overly loud. I'm running with stock catback and AEM intake (purchased Grimspeed adapter to fit to stock catback). You can feel that the car just wants to go now. Getting some pretty good torque even in 5th and 6th gear.

  5. Great Product!

    By Aaron March 1, 2017

    This is worth the price. Easy to install ( minus that stubborn stud nut on the top right), everything fitted together nicely, and it sounds amazing. Goes great with my Cobb accessport and Cobb intake!
