Product Description

If you drive a GR Hatchback (08-14 STI or 11-14 WRX), you know the factory exhaust is a tragedy. It’s heavy, it suffocates the turbo, and it sounds like a vacuum cleaner. The COBB Tuning Cat-Back is the fix, and we give you two ways to get there.

The Stainless Steel Classic This isn't your average muffler shop job. We engineered a dedicated "Suitcase" Muffler that houses a straight-through Reversed Y-Merge. Instead of hitting a brick wall of baffles, the exhaust gases are smoothly split into dual 2.5" outlets. This design virtually eliminates back-pressure, letting your turbo spool faster. Crafted from TIG-welded 304 Stainless Steel, it’s built to survive road salt and speed bumps while delivering that deep, resonant rumble COBB is famous for.

The Titanium Flex For those counting ounces (or just wanting to show off), the Titanium Series is the ultimate upgrade. We swapped the steel for Grade 4 Titanium, dropping the system weight to a ridiculous 24 lbs. We use a bespoke muffler design to filter out the "tinny" rasp that plagues cheap titanium exhausts, leaving you with a crisp, exotic pitch that screams race car. Finished with Blued Titanium Tips, it’s a centerpiece for your build.

We know Subaru owners hate drone. Whether you pick Steel or Titanium, our systems are tuned to stay within SAE sound standards. You get the presence you want at wide-open throttle without the headache during your morning commute. The Quad Tips are the finishing touch—they protrude just enough to show off the laser-etched COBB logos, proving you didn't compromise on your build.

This is widely considered the "Goldilocks" exhaust for the Subaru Hatchback. It balances flow, build quality, and sound better than anything else on the market. Whether you want the durability of the 3" SS or the exotic flair and weight savings of the Titanium, COBB gives you the voice your Subaru was born to have.
