Upgrading your Focus RS exhaust is the next best thing you can do to a downpipe for a boost in performance. Not only will the new 3" piping from the Borla Focus RS exhaust help eliminate some restriction in the exhaust system, it will also give you an aggressive tone that sounds perfect cruising down the road while at part throttle and while you go wide open. Borla's exhaust system for the Focus RS is made of 304 stainless steel for great durability and will last a long time. Take your pick of polished or carbon fiber exhaust tips!
Borla also includes a sound suppression simulator eliminating any potential check engine lights. Borla's exhaust system eliminates the valve function and allows flow at all times.
