Exhaust was delivered in a timely manner and well packaged. After watching all the installation videos available on YouTube the installation was very easy. Paid less than $500 for the T409 Stainless Steel system with free shipping. Thanks AutoAnything!

I have listened too all of the catback available, and this was the best for my taste! Deep low tone, quiet when cruising and loud but bot too much when flooring it! Sounds even deeper than the video on youtube. And fast shipping!

Let's face, it's a 4cyl focus at the end of the day. It's not a muscle V8. That being said, its still fun to hear a bit more volume, especially on the ST. Its very smooth sounding, louder under heavier loads, and near silent while cruising. Its the exact sound you want for being able to enjoy the sound from inside the car when you want it, without being 'that guy' from the outside. A removable resonator (replace with a straight pipe) will make it louder if you want to make more noise.

Great system!! Good directions. Best sound out there of the 10 plus systems made for the ST in my opinion. Hardest part was getting the car high enough off the ground.

3" catback was very easy to install, fitment was good. The slip on design is a little lower quality, but all in all it is a great full system for the money.

The catback for the focus st is super easy to install. It sounds great and everything is bolt on. No welding or pipe bending needed. It was pretty easy to install. No real issues. Reusing the hangers were kinda tricky and required some finess with a few pipe sections but other than that it was pretty easy. The information won't go wrong with this catback.

For the price of this exhaust you get a pretty decent value. Construction seems solid.
