The Cobb Tuning 3" Stainless Steel turbo-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 gases 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.
The downpipe's cast bellmouth and high-flow catalytic converter provide optimal exhaust flow.
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.
