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.

Nice exhast

This was a complete and utter pain in the ass to install because I had to do it in my driveway and only had one jack to lift and two to hold the car, which left less than the recommended 15'' clearance required to install the exhaust, but it can be done. It came with everything it said it would. Fits my 2007 ford focus SE wonderfully. My car accelerates faster and is a wee bit funner to drive. If it becomes a project car, i'll come here for the parts.

Great exhaust

Great quality. Fits great. Sounds great. Not too loud. No drone. It made my 2007 Focus much funner to drive. I highly recommend this exhaust.

Great catback, loud than you might think

Here's the breakdown. First week- %100 loud exhaust. Second week- %70 loud exhaust. Third week- %50 loud exhaust and stays that loud. Install was easy, and it came with all the necessary hardware and instructions. At idle it does rumble very nicely and at acceleration, sounds like a beast. BUT I HATE THE DRONE, usually happens at 2 rpm. So If you want an aftermarket catback but not an overly loud one, buy this one. As long as you can tolerate the drone.

Great Exhaust

This is a very nice American made exhaust for a good price. Put this on in about 20 minutes and everything lined up great. Upgraded from a straight pipe to this and I could instantly feel power come back and the car is a little snappier with throttle response. Great quality piping, muffler, and tip. The sound isn't anything crazy, but it does have a nice deep end rumble. I would recommend this exhaust to anyone with a duratech!

Almost perfect.....!

Arrived yesterday, installed today in a couple hours, and that was taking my time. Great mellow sound and great fitment. My only wish would be that the tailpipe/tip was 3/4" to 1" longer so the tip would show better Other than that, great product with great looking quality! Thanks!
