The AWE Catback exhaust offers perfect fitment, patented drone-canceling 180 Technology®, aggressive tip options, and a soundtrack that only AWE can deliver, all proudly engineered, designed, and manufactured in-house, in the USA. Presenting the AWE Exhaust Suite for the 2015+ STI!

The Touring Edition Catback is for drivers who like their BOXER rumble to be deep, hearty, and full of crackles all without any interior drone at cruising speeds. A direct bolt-on, full 3” straight-through design with a resonated mid section and tailored mufflers in the rear, the Touring Edition acts as the sophisticated, drone-free member of the STI exhaust suite. If you’re looking to liven up your commute while retaining civil in-cabin characteristics, this version is for you.

Thanks to the design and construction of 180 Technology® resonators, the internals will not break down and degrade over time causing tone change. Full-bodied rumble for life from the point of installation.

This configuration provides the best ratio of interior refinement and exterior rumble on the market.


  • Proudly engineered, designed, and manufactured in-house at AWE, in the USA
  • Rasp-free, aggressive BOXER® tone without the drone
  • Max gains of 11 hp and 11 ft-lbs of torque at the wheels
  • Touring Edition features AWE’s proprietary drone-canceling solution, 180 Technology®, tuned specifically for the EJ25
  • Handcrafted from 3” CNC mandrel-bent, U.S.-sourced .065” wall T304L stainless steel
  • Direct bolt-on for factory-like simplicity
  • Less is more: clean, straight-through design maximizes performance
  • 102mm quad tips in diamond black
  • Perfect fitment, guaranteed
  • AWE No Check Engine Light Guarantee
  • Lifetime warranty (one year on tip finishes)

Awe Touring in 2019 Wrx Sti

I did a lot of research and this was my favorite sounding exhaust that wouldn't completley piss off my neighbors when warming it up in the winter. Also, no Drone!!! It really hits hard when you rip on it, but also can be a lower sound when needed (like cops beside you in VA)Perfect fitment and no leaks. Took about 1.5 hours for a first time exhaust install.
Ps. I also ordered the black tips and recieved a letter in the box stating they will send out the black tips when available due to supply demand, and they sent me chrome ones for now so I could get it installed earlier instead of waiting. I ended up getting the black tips 1 week later and free of charge. Now i have chrome and black tips for the same price as just the black tips. Love Awe.
