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.

FSWERKS FSWERKS Stainless Steel Catback Performance Exhaust System - Ford Focus ZX3/ZX5 Hatchback Duratec 2003-2007 Review

Sounds amazing, not too loud.

Overall it was an easy install took about 40 minutes with a hack saw and some hand tools! Highly recommend changing the flex pipe gasket while you're down there, mine was shot.

Quality product�

Very good quality exhaust system, not too loud or quiet, just right! .The throttle response is much smoother and feels like the engine is less restricted too! A+

Great product

The removal of the stock exhaust was the hardest part of the install it went in very easy and I did it by myself in my garage it took about an hour. It had a deep growl to it and sometimes gives off some pops defiantly changed the car, will defiantly be buying from here again.

Sounds great

Ordered online, waited a 5 days for shipping, (cali to ny). The guy that installed it says it wasnt has easy as clamps and what not, he had to weld and cut pipe, but he made it work. Everything so far is great!

Got a Street Performance catback exhaust and couldn't be happier with the sound! Nice and smooth in the low end but man, does it roar in the high revs
