The 2011+ Subaru STI Cobb Tuning Cat-Back Exhaust uses 304 stainless steel 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. 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.
