COBB Tunning 515301 Turbo Back Exhaust Kit 08-11 Subaru STI
The COBB Turbo Back Exhaust System for the 2008 and newer Subaru STI hatchback. This much anticipated exhaust 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 full turbo back exhaust.
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. 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.
The COBB Turbo Back Exhaust System for the 2008+ Subaru STI is a triumph in design and execution. Install the COBB Turbo Back Exhaust System on your STI and experience performance like no other.
