COBB Tuning Catback Exhaust System for Subaru Impreza WRX & STi

COBB Tuning Catback Exhaust System for Subaru Impreza WRX & STi

Exhaust gases are directed through 3-inch diameter tubing into the center inlet of the fully 24-inch wide muffler section. Within the muffler, the gases pass through a reversed Y merge, efficiently dividing the exhaust into separate muffling chambers on each side of the canister. Symmetrically, 2.5-inch outlets emerge from each side of the canister, guiding the exhaust out the rear through quad-polished exhaust tips. This straight-through exhaust design significantly reduces exhaust back pressure, as demonstrated in the illustrations below. Crafted entirely from 304 stainless steel, the exhaust system boasts meticulous TIG welding throughout for exceptional appearance and strength. Four custom exhaust tips seamlessly fill the factory bumper cut-outs, with just enough protrusion to display the COBB logos etched into the top of each polished tip. Perfect fitment is ensured with either the Subaru factory downpipe or the COBB 3″ SS downpipe. Representing a triumph in design and execution, the COBB 3″ stainless steel cat-back exhaust for the 2008-2014 Subaru STI hatch and 2011-2014 WRX hatch promises unmatched performance. Enthusiasts can elevate their STI or WRX driving experience by installing the COBB 3″ SS cat-back exhaust and discovering unparalleled performance.
