COBB Tuning Cat-Back Exhaust Stainless Steel Hatchback 2011-2014 WRX / STI
The COBB 3" Stainless Steel Cat-back Exhaust for the 2008-2014 Subaru STI Hatchback uses a unique straight-through muffler section rather than common chambered designs, which minimizes tubing bends, reduces back-pressure and keeps sound output below SAE standards. The outstanding craftsmanship and attention to detail are evident in every aspect of this cat-back. Exhaust gasses are guided through 3 inch diameter tubing into the center inlet of the fully 24 inch wide muffler section. Internal to the muffler, the exhaust gasses pass through a reversed Y merge, efficiently splitting the exhaust into separate muffling chambers on each side of the canister. 2.5-inch outlets emerge symmetrically from each side of the canister and direct the exhaust out the rear through quad polished exhaust tips. 304 stainless steel is used throughout the exhaust construction. All components are meticulously TIG welded for outstanding appearance and strength. Four custom exhaust tips fill the factory bumper cut-outs perfectly, protruding just enough to show off the COBB logos etched into the top of each polished tip.
