The popular Killer B Motorsport 321 Stainless Steel Holy Header is a great way to increase the exhaust flow due to the smooth bends in the design that will optimize the exhaust flow. This will help maximize the flow potential of your turbocharger which will also reduce the spool time. This is an equal-length design that will produce an aggressive exhaust note while improving the performance and response throughout the entire RPM band.
NOTE: May not fit some Forester, Outback, and Legacy models with the OEM oil cooler
