COBB Cat-Back Exhaust System Stainless Steel 3" Focus ST 2013-2015 is rated 4.5 out of 5 by 4.
Rated 5 out of 5 by from Great quality, addicting sound! This exhaust system is by far the best quality system I have found for the Focus ST. Flange connections make sure the joints don't leak, full stainless steel, and a simple installation. When they say drone free, they really mean it! And when your on the throttle, your treated to an awesome low end tone! The sound is truly addicting, and very pleasing to your ears. I'd recommend this system to any ST owner, I truly believe its second to none. Well done Cobb, WELL done!

Rated 4 out of 5 by from Nice look and sound I would give it 5 stars, but when I bolted everything up and used the cobb hangers, it was misaligned to the right, so much so that I had to have a muffler shop cut part of it and re fit it. It might have been caused by my lack of experience installing exhausts. Besides that, this exhaust is absolutely awesome. It gives a really nice growl at idle that isn't loud, but you can hear it. When you get on it it's awesome. It very easily passed the wife test.

Rated 5 out of 5 by from Piece o' Cake for 2015 ST Fits the 2015 ST and is an EZ Install. It takes longer to unpack it, get set up than it does to replace the exhaust. I didn't need any hanger pliers as my car is only a month old. I had to bend some heat shield out of the way (and back) when fitting the pipe over the rear axle. The actual work took less than 20 minutes. My 8-year old son helped my out with fitment and the awesome test drive!

Rated 4 out of 5 by from Makes car more special. I've had this cat back installed for about two weeks now and I have no complaints about its performance. It doesn't drone when cruising, it's deep and loud enough when you want it to be, but it won't annoy your neighbors when you're just driving around town. Great sound! Also, super high build quality. Zero fitment issues.
