Product Description

Roush 3" Cat-Back Exhaust Kit for all 2013, 2014 and 2015 Focus STs.

This Roush Exhaust kit has a performance-flow muffler and uses 3" diameter tubing that helps the turbocharged Focus expel gases faster for increased power. Mandrel bent 409 stainless steel tubing also helps to achieve optimum air flow in this system. The whole exhaust system utilizes factory mounting locations for a straight forward install that you can do yourself, at home, with only basic hand tools.

Kit Includes:
- Performance-Flow Muffler
- Mid-Pipe Assembly
- Y-Pipe Assembly
- Dual 4" Exhaust Tips
- All Necessary Hardware
- Installation Manual

Please Note: Ford designed the 2015 Focus ST with four exhaust hangers but only added three on the factory exhaust system. All aftermarket exhaust systems are built to use that fourth exhaust hanger. CJ Pony Parts recommends the purchase of COBB’s Polyurethane Exhaust Hanger Kit (591001).

This Roush 3" Cat-Back Exhaust Kit for all 2013-2015 Focus STs features dual, 4" round 304 chrome flashed tips with rolled edges and stamped Roush logos, center exiting the car. Roush's cat-back enhances the exhaust note and pitch of your Focus ST for a high performance sound that will surely garner some attention. Between the large diameter piping used, the straight forward uninhibited air path and performance-flow mufflers, this exhaust kit will achieve some significant horsepower and audible performance gains.

Roush Cat-Back Exhaust Kit 3" Focus ST 2013-2015 is rated 4.2 out of 5 by 5.
Rated 5 out of 5 by from Awesome Sound I bought this exhaust about a month ago. I had reservations because I had read several reviews saying it was too loud. For me, that was not the case. The exhaust has a deep tone that sounds great when you're accelerating quickly and has a nice little burble when decelerating. As much as I love it, however, it does have a drone when you're out on the highway cruising at 70+. I wish this were not the case, but it is. This is not so much a problem for me. I don't mind it. But I know if my girlfriend were to come along for a ride, it would annoy her. Overall, I give the product my recommendation and five stars. Also, CJ Pony Parts delivered the product extremely fast. It may be different for you, but it took them only 3 business days to deliver this to me and it was FREE.

Rated 4 out of 5 by from Starts out loud but mellows out Bought this exhaust because I wanted something that sounded mean, but was not overly expensive. Many people have expressed concern with it being too loud. I'd have to disagree. The exhaust is loud between 2500 and 3000 rpm, but very mellow everywhere else in the range. For the first 500 miles the exhaust is very loud, but once it breaks in the sound is deep and not overly loud. In my opinion it sounds like it should have from the factory, like a performance hatch. In terms of performance, throttle response is noticeably better, but I don't think there is much hp increase. Overall, great option for an inexpensive exhaust.

Rated 2 out of 5 by from Drones I can be first and second to review this, because my prior review was deleted, because it wasn't 5 stars? Keep your stock exhaust, or if you have to have it loud, go with Ford Racing. This system drones and the car just isn't fun to drive anymore. Scout around the forums, you'll see. Quality is top notch, looks OK, but overpriced like the all the others

Rated 5 out of 5 by from Best sound i thought could come from a 4-cylinder Excellent, hi-level sound quality, blows all those cheesy raspy subies, etc away. Is on loud side but what else could someone with a car like this want, especially modified, sounds nothing like a 4 banger, very impressed with quality.

Product Questions

Can I use this in my regular ford focus?

Asked by: ebitrios
I just bought this exhaust kit and it comes with an extra adapter for use with the non ST focus. So according to roush it does work on a non ST focus.

Any idea what the expected gains are for this exhaust? 

Asked by: Atkins7288
The gains are modest from this exhaust. It helps improve air flow exiting the vehicle and is lighter, which results in a bit more power, but nothing out of this world.
