The Borla S-Type axle-back for the Subaru Crosstrek is tailored for the 2.0L and 2.5L boxer engines. The S-Type sound level helps bring out the character of Subaru's flat-four and features a 3.5in x 2.75in oval polished T-304 stainless steel tip. Whether driving in the city or heading off the pavement, the system stays drone-free. T-304 stainless steel construction adds durability over the stock exhaust, while ultra-smooth mandrel bends and precision CNC manufacturing ensure maximum flow and an accurate fit. This axle-back installs behind the factory catalytic converter and retains all factory emissions equipment. It is made in the USA and backed by Borla's Million-Mile Warranty.
