Product Description
If you drive a GV or VA chassis WRX or STI, you know the factory exhaust is a tragedy. It’s a heavy, restrictive boat anchor that makes your rally-bred machine sound like a vacuum cleaner. The COBB Tuning Cat-Back Exhaust is the fix, and we give you two distinct ways to solve the problem depending on your budget and your build goals.
The Titanium Featherweight (The "Grail" Part) - For the driver who counts every ounce, the Titanium Cat-Back is the ultimate flex. Tipping the scales at just 24 lbs, it drastically reduces the weight hanging off the rear axle—weight you can actually feel disappearing 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 stunning Blued Tips, it tells everyone at the meet you didn't compromise.
The Stainless Steel "Rock" (The Daily Driver) - If your Subie sees rain, snow, and daily commuting, the Stainless Steel Cat-Back is the industry standard for a reason. We didn't just weld some tubes together; we engineered a Cast Y-Split. Unlike cheap welded splitters that crack over time, this cast section is indestructible and flows smoother. We paired it with Bespoke COBB Mufflers designed to be the "adult" choice—deep and throaty when you mash the throttle, but civilized enough to take a phone call on the highway.
Titanium is notoriously hard to weld, and cheap Stainless flanges warp and leak. COBB refuses to cut those corners. The Titanium systems are back-purged with argon gas to ensure the welds are as strong as the tube itself. The Stainless systems use High-Quality Cast Flanges and MLS Gaskets to ensure a leak-free seal for the life of the car.
This is the "Endgame" exhaust choice for the Subaru Sedan. 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. Whether you go for the exotic flair of Titanium or the rugged reliability of Stainless, you get the signature COBB fitment that has defined the Subaru community for decades. Stop driving a legend that sounds like a sewing machine—let it breathe.
