The Sleeper

I like no I love this stealth package !! If you're going from straight pipe like me you're going to notice the torque and power difference right away I sacrifice sound for performance and I'm okay with that ! It's got a clean deep sound like a stock performance exhaust would if that's what you're looking for this is the setup ! The car sounds like it should ! Not to mention how easy it was to install. You only need to make one cut and the rest is both off The only struggles of course are those two rusty exhaust bolts but nothing PB blaster can't fix !

Stealth Exhaust Set Up

I was tired of replacing rusted out exhaust (original Ford exhaust lasted more than 12 years, the aftermarket replacement less than 2), so I purchased and installed the Fswerks stealth stainless steel exhaust system on my 2007 Focus ZX3 2.0L and it sounds great! Nice rumble when you plant your foot in it, a little louder than stock; definitely not ricer sounding at all!

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.
