Agency Power 2013-2018 Ford Focus ST Catless 3in Downpipe

One of the first upgrades you should make to your Focus ST after you replace the shocks & struts is replacing the factory exhaust. However, if that modification falls out of the scope of upgrades you plan to make in the immediate future, or if you simply aren’t looking to replace the stock exhaust system for any reason at the moment, but you still want to help your turbocharger out, then you should definitely consider a new downpipe.

The Agency Power Ford Focus ST Catless 3-inch downpipe offers several benefits you can easily reap without going through the trouble of replacing your entire exhaust system. First, it is designed modularly, making it an easy fit for stock exhausts, aftermarket exhausts, and Focus ST turboback exhaust systems.

The other, and most important, reason you need a new downpipe has to do with unrestricted airflow; this is especially true if your Focus ST is equipped with a turbocharger. Essentially, a turbocharger is a system of pumps, and your exhaust system is a series of pipes. By improving the airflow with new, better pipes, you’ll allow your turbocharger to freely pump air more efficiently. Furthermore, your turbocharger’s spool-up time will dramatically improve.

How do downpipes work?

1. Connections - Downpipes connect the exhaust manifold to the catalytic converter

2. A cure for the bends - Standard exhaust systems are usually made up of pipes with several bends. By using straighter downpipes, air can travel more quickly and freely.

3. More space, less distance - This downpipe from Agency Power is larger in diameter and shorter in length than the factory Focus ST downpipe. Because of that, more air can travel a shorter distance, thus improving the overall function of your vehicle.
