The Cobb Tuning 3" Stainless Steel Cat-back Exhaust for the hatchback model 2008-2014 Subaru STI and 2011-2014 WRX 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 evacuated through 3-inch diameter tubing into the center inlet of the 24-inch wide muffler section. 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. This straight-through exhaust design is much more effective at reducing exhaust back-pressure.
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. All necessary hardware is included for installation.
Fits 2008-2014 STI hatch and 2011-2014 WRX hatch.
