Thermal R&D 2013+ Ford Focus ST 3" Cat Back Exhaust System

Forget the Cobb. This has got to be the best sounding exhaust for this platform. No drone at idle or cruising speed, but it is plenty loud at WOT. This exhaust will give you a deep, smooth, and consistent tone that will never be annoying.

I purchased this and a catted downpipe and this exhaust took 3 months to get to my door...but it was well worth the wait. It was just the exhaust I wanted. Quiet enough while cruising but you can hear that the vehicle is definitely on. Stock exhaust was too quiet. With this exhaust setup with a catted downpipe, it will roar at WOT, but thats what I wanted. It is also quiet on startup and won't wake my 3 young children.

Best exhaust system I've ever had. Was a little tricky installing, but once it's on there it's fantastic. Came with all the hardware and the extra hanger that's needed for install. The sound is perfect to me. Can cruise around nice and quiet in town or on the highway, but get on the throttle and boy does it open up. It never drones unless you're doing over 90 maybe, it really is the perfect exhaust for this car.

When your on the gas its roaring like a lion, when your just cruising it purrs like a kitten.

I did not order mine from this website but I still wanted to leave a review. This exhaust system is by far the best you can buy in any category. It sounds better than all of the other systems, I've hear Cobb, MBRP, Miltek, except one.......CPE. But CPE did the plain boring dual round tips, what a let down right?

This system is super loud when you want it to be and very quiet when you want it to be. There it barely any drone at all, of course there is more than if it were stock. The CPE has slightly less drone but also it's peak loudness is noticably quieter so the trade off isn't worth it when you consider the customer tips you get and the overall quality and adjustability that comes with Thermal.

There are 2 sleeve clamps that allow the adjustment of the overall length, there is a shoulder/knuckle connection at the rear end that allows you to get the tip perfectly level no matter what, then the tip slides over the pipe so you can get it perfectly center and adjust the height of it to your preference. I was extremely impressed by everything about this system.

Just wish Thermal R&D included a 3" adapter for if you already have a 3" DP, that's the only flaw with the entire system.
