Product Description

If you are building a 2002-2007 WRX or STI, you aren't just driving a car; you're driving a rally legend. But let's be real—the factory exhaust is a heavy, restrictive boat anchor that strangles the EJ engine. The COBB Tuning Cat-Back Exhaust is the ultimate tribute to that heritage, offering two distinct ways to unlock the flow and sound your Subaru deserves.

The Titanium Featherweight - For the driver who counts every ounce, the Titanium Cat-Back is the holy grail. Tipping the scales at just 17.25 lbs, it drastically reduces the unsprung weight hanging off the rear of the car, which you can actually feel in the corners. Titanium exhausts often get a bad rap for sounding "tinny" or cheap, but COBB solved that. By engineering a custom Straight-Through Oval Muffler, the rasp is filtered out, leaving a refined, exotic metallic pitch that screams motorsport. Finished with a stunning 4" Blued Tip, it tells everyone you didn't compromise on your build.

The Stainless Steel "Gentleman's Exhaust" - If your WRX is a daily driver that sees rain, snow, and speed bumps, the Stainless Steel Cat-Back is the industry standard. COBB designed this to be the "adult" choice in a market full of loud, obnoxious pipes. It uses a polished resonator and a specially tuned muffler to deliver that classic, deep Subaru burble without the ear-bleeding highway drone. It sounds expensive because it is. Crafted from 304 Stainless Steel with artwork-level TIG welds, it’s built to outlast the car itself while keeping you fly-under-the-radar with the authorities.

Titanium is notoriously hard to weld, and cheap Stainless rots out. COBB refuses to cut corners on either. The Titanium systems are back-purged to prevent cracking, and the Stainless systems use thick flanges that won't warp. Whether you want the raw, lightweight performance of Grade 4 Titanium or the timeless durability of Stainless Steel, you get the signature COBB sound and fitment that has defined the Subaru community for decades.

This is the "Endgame" exhaust choice for the GD chassis. It gives you the flow required for Stage 2+ power, the build quality of a show car, and a sound profile that respects the neighbors while thrilling the driver. Stop driving a legend that sounds like a vacuum cleaner—let it breathe with COBB.
