Install was great and easy

It was super easy to install took max like 30 mins on the lift. Sounds amazing, definitely not loud until you get on it. Honestly droned less than the factory exhaust. One complaint I guess would be that the tip doesn't stick out far at with the SAP kit.

Much better than stock

The hardest part of the install is getting the old exhaust system removed. The FSWERKS system fits in place easily after that. Glad I went with the stealth version as it provides a nice exhaust note that doesn't drone on long highway trips.

Great quality - a bit loud

I installed a stealth system on my 2007 Focus 2.0 five speed. I wanted a stainless system so it will survive our winters. The installation was very easy - I had to cut the two flange bolts and cut the pipe to get the old system off. The Stealth system fit perfectly. The bends are beautiful and welds are nice. I went and bought some band clamps to use instead of the provided u-bolt clamps. Band clamps will let me take it apart easily, if necessary. This system replaces the second catalytic converter. That converter is not monitored by OBD so you can get away with it. Unless you're in a state with a visual inspection - I am not. The mufflers are magnetic. They may be 400 series stainless..? The sound is great at idle and taking off from a stop. It's a little louder than I would like when going down the highway at 80 MPH. With my little car and the five speed, I'm buzzing it over 3,000 RPM at that speed. If I slow down to 70MPH, it's not bad. In years to come, if the mufflers get louder, I'll cut one of the straight-through mufflers out and install a stainless Moroso spiral flow.

So far so good

Well getting the original system made me sore for 3 weeks. Took about 3 hours to remove and cut it down to size to fit in the trash can. Installing the new system took about 30 minutes. So with the new system installed and test driving, sort of strange to me. Car sounds slow but I’m going fast. I dont use the radio and drive with the windows rolled down so I hear everything. At first it was pretty loud but now my ears are sort of tuning out the sound and I’m getting use to it. Overall my old system was leaking; 15 years old and I needed a replacement. As far as performance goes I don’t any point of measurement, so I make a claim that my car is faster or I would be lying. But it sounds cool. At any rate, I don’t have the tune or build needed to see the full potential of the system to give it accolades for performance and enhancement.

Easy install, great sound!

Installed outside in my apartment complexes parking lot. Super easy to install, taking old system off was more difficult. Great low sound.
