This BORLA(r) Cat-Back(tm) system is tuned for performance and sound for both the 2.0L engine in the WRX and the 2.5L engine in the STI. Our S-Type sound level is designed to bring out the Subaru Boxer engine rumble and provides an aggressive sound without the drone. This system features 3.5" quad high temperaure black coated T-304 stainless steel tips, but is also available with polished T-304 stainless steel tips. For ease of installation, this Cat-Back(tm) is a direct bolt on part and does not require cutting. Like all BORLA(r) exhaust products, each system is handmade in the USA by master craftspeople and features premium, high-quality T-304 austenitic stainless steel construction, ultra-smooth mandrel bent piping, and a Million-Mile Warranty.
