My review

Fast shipping and excellent packaging. The muffler had a dent in it, which occurred prior to packaging. I didnt feel it was damaged enough to cause problems. Simple directions and easy installation. Acceleration is more responsive, and the exhaust tone sounds great!

Hi Andrew, I am sorry your received a dented muffler in your system. We try our best to insure our parts are well packaged and unfortunately sometimes the heavy boxes are dropped by the shipping company causing this kind of damage. Please be assured that this will not affect the performance or warranty of our system. Thanks very much for your feedback and sharing this experience :-) FSWERKS Team

Works great, opens 'er up

Im sure if you have the car you're aware how zippy the thing is. Your gears feel like a close group of friends because theyre so short and fast you can be in 5th at 37mph and be chugging along fine. Well if you get this exhaust, you can now be in 1st all the way up to 37mph before you hit limiter. Of course, in such a case you could expect to be spending more than you had already disliked on gas, but it paints a picture. Your HP certainly goes up a little and you get to be loud without being deafening, unless, of course, you happen to have your window down when you hit that money shift next to a wall or passing vehicle, in which case, you might expect to need hearing aids 40 years sooner than you had expected. Its a fun toy with performance increase that makes the car all the more fun and at a reasonable price. Installation was seamless (with the usage of a circular grinder for removal of the stock)

Easy Install and quality product

Fit great easy install. Sounds great with the stock header and pretty loud with the race header. Still tuning the car so I have not taken it up past 4600 rpm but I am sure it is going to scream at around 6500.

Sounds great

Happy but could be better

Love the system however the length and shape created issues on install. I had to pay a shop to modify it because it didn't sit correctly and was causing the downpipe to leak which resulted in a smelly and noisy several days before I could get it into a shop. It's still affordable enough that I'm okay with that but it was annoying.

Thanks for your feedback Nathan :-)



the sound is magnificent on my Ford focus 2007 se, very bass sound, not too loud, not too discreet either with a fairly satisfactory rumble and aime pop. it took 45 min-1h max to install, fit perfectly. Very happy with my purchase!

A great replacement for an stock exhaust.

I bought the exhaust too replace my old rusty worn out stock exhaust for my 2003 ford focus zx3. The install was a little bit tight in some places. You really have too put some force specially with the midpipe too get it on perfect, I also ordered a replacement flex pipe from FSWerks as well. Both were super easy too install in all honesty and they gave me extra hardware just incase. I would definitly recommend this exhaust too someone. The sound is great it is nowhere near loud though so there is no drone it just sounds more rumble and a lot more backfire noises especially when coming too a stop. Which is exactly what I wanted. in 5th gear at 65MPH which is the highest speed limit here in maryland, You do not notice it which is great because I like too take long drives and trips too places and that would get old really fast. It is stainless steel so i expect it too last for at least 17 years speaking the old exhaust lasted that long and it was just regular steel. an easily 10/10 I have had the exhaust on the car for about 2-3month and no complaints.

Great product

The exhaust was easily installed and looks beautiful. It has a nice grumble and pops at low rpm while not droning on obnoxiously on the highway. Very fine product so far. Only issue I've had is getting it all to fit perfectly in the space provided. Be aware fire walls may need to be bent to install but wont rub if moved back afyerwards.

Matt O.

Top Notch!

I'm really impressed with the quality of this exhaust, especially for the price. It lines up with all the factory hangers and has plenty of clearance, so it couldn't be any easier to install. The welds are clean and all the bends look nice and make sense. It has a nice deep tone and it significantly reduced the drone inside the car at highway speeds. Feels like it didn't loose any low end torque, noticeable gain in the mid-range, and throttle response seems better.

Very impressed by this product. The sound is perfect. Install was very simple, took about 20 minutes (if that) at my shop with a lift. Very good exhaust.
