We use 2.5" diameter mandrel bent T304 stainless steel tubing in our designs for maximum flow and horsepower. FSWERKS systems come with our exclusive stainless steel high-flow straight-through design muffler and are finished off with a beautifully polished 3.5" angle cut T304 stainless steel tip. Also included are the necessary clamps and hardware to allow for an easy installation. All our stainless steel systems are backed by a 5 year limited warranty.

For Duratec Focus owners who wish to have an exhaust that is 100% C.A.R.B. legal in all 50 states, we are now offering our FSWerks Street exhaust system. Some Duratec Focus models have two catalytic converters, with the second being in the middle portion of the car. Our Stealth and Race versions of our exhaust keep the primary catalytic converter that is part of the exhaust manifold, but will eliminate the secondary unit further down. This option will keep the second converter in place and allow you to remain completely street legal if your Focus had two catalytic converters from the factory.

2010 focus coupe performance exhaust

I'm 22 and was very iffy about getting it since video sound doesn't do any justice. I hate the sound of civics and most wrx. But this exhaust...wow this one is my favorite for any 4 cylinder. Its deep, perfect loudness (if you're looking for something to wake it up a bit) and overall just great. My focus is a 5 speed and it made it WAY more fun to drive. Sounds just like an st without a turbo. People complained about the drone...i never noticed one. My car had a small one with the stock exhaust on it and I still don't think its changed. If you want something deep and a wake up for your focus get the performance.

Sounds Amazing!

This exhaust was easy to install and sound so much better than stock. This exhaust has a low and deep rumble that sounds amazing.

Excellent product!

Gives the exhaust some growl and bite that was not there before. Coupled with the ITG intake, this was a very nice addition. Awesome job, FSWERKS!

Great Exhaust

Was the perfect exhaust for a daily driver! Easy installation took about an hour and a half with jack stands.
