Ford Focus ST/RS Exhaust & Intake for Performance Vehicles

One of the first and easiest performance enhancements that you can do for your Ford Focus is upgrade its internal air-processing functionality. The primary systems that you will alter to upgrade your car’s performance will be the intake system and the exhaust system. Mountune USA has everything you need to perform a Ford Focus ST/RS exhaust upgrade or Focus ST/RS intake upgrade, from small parts like exhaust valves to performance packages with crucial intake or exhaust parts included.

Performance exhaust and intake systems are specially designed to provide the ideal environment for air to flow through, maximizing the scavenging effect across a range of RPMs. When air can travel through a performance exhaust system easily, your car is able to then bring in more air. Air contains oxygen, which is a primary reactant in the combustion of fuel inside your engine. More air, therefore, means more combustion, which translates to more power. This is one of the best reasons to perform an intake or exhaust upgrade, but some car enthusiasts are also drawn to the deep “growl” that is sometimes heard with an exhaust upgrade.

All mountune exhaust and intake products are made from high-quality materials, including stainless steel and nitrided metal.
