Sport exhaust system

10/10 fitment. The sound is low deep tone and has no drone at all which is good, but I do wish it was a bit louder on wide open throttle. Other than that, cannot complain at all. Fit on 2019 FiST

Amazing Quality and Sound

Easy installation, quality sound, and great customer service. I literally made my decision via IG communication and sound clips that FSWerks had posted. This exhaust is exactly what I was looking for. Bigger tips, a tad more sound over stock, and wife approved in regards to drone (none). Car doesn’t bring much attention unless I mash the gas. I love it. Now I just need to order my FSWerks license plate and eventually an intake. You guys rock. -Chris L IG: CP_Lott

Great Budget Exhaust for “sleeper” mode

I was looking for a cheap but great quality exhaust for my Fiesta ST 2019. It is really easy to install if you have how to lift the car. Everything fits perfectly but you might need 2 persons to align correctly the exhaust. BTW, the exhaust was exported to my country in Latin America without any issue!

Perfect upgrade from factory

Fantastic system. Very high quality welds and joints. Sounds is perfect. Slightly louder on idle but much louder on wide open throttle. Would definitely recommend.

Amazing Exhaust!

Been running with the exhaust for a few months and I love it! Makes the car sound a bit meaner and louder! Get some pops when shifting or downshifting if done just right! No drone! Drove for two hours to Santa Barbara and the whole drive was comfortable with no drone. It sounds amazing in the mornings on a cold start. Not to loud unless you want it to be, then floor it! Great exhaust!

Great System ... No Disappointments

Product delivered exactly as in photos. Took me 2hrs to install since I had to use a hacksaw to cut the OEM tailpipe. Installation was a breeze with the pipes sliding together without any issues and the heavy duty clamps. I ordered a aftermarket exhaust gasket and the COBB hangers, but since this system is lighter than the OEM system, the OEM hangers probably would have been fine. I extensively researched the systems on the market before deciding on FSWERKS. I was looking for verified torque/HP benefits with a mild increased sound. It's exactly what I wanted. Thank you FSWORKS.

Great system and works with trailerhitch

Called 1st to ask questions. I have the trailer hitch installed. The guy I spoke to upfront honest said he didnt know how the system would work with the hitch. He gave me measurements, checked and took a chance. No worries it goes together better than with stock exhaust. I had knocks on rough bumps with stock. None with fswerkz system. Again sound great worth every penny. Super easy to install. Instructions dead on.

I like this exhaust

Easy to install. Sounds awesome! It's not too droney on the highway, but makes the car sound more aggravated than stock.

Fiesta St Exhaust

I'm a 74 year old rodder, now reduced to driving a tuner, hahaha....needed a little punch & exhaust note for my little ST, so went with a FSWERKS cat back system. Easy installation, quality system, not too loud, exactly what I was looking for. Would recommend it highly to anyone!

Awesome exhaust

All the awesome noise you want with zero drone. It gives a lot of burgles on deceleration and the cold start was more aggressive than I thought would be too. Changes all the noises in the best ways without the drone and I couldn't be happier. Cheaper than many other name brands out there which is a huge plus. Paired with a Whoosh catted downpipe

Minor confusion

I bought this exhaust for my car 2-3 years ago. I noticed there seems to be a whole in the muffler in the bottom. One of my friends suggested that is was intentional to let out moisture. I'm not sure. Other than that. On stock turbo and stock downpipe it drone a tad until it broke in more. With a hybrid turbo and hiflow catted downpipe it droned less. With a bigger turbo and catless downpipe there's NONE. I put 1000 miles a week on my car and this is the right amount of loudness. I highly recommend

Perfect for city vehicles

Super great exhaust, slightly louder at cold start, but quiets down after 20 seconds. Sound super good under throttle, just the perfect tone without the rasp that is not always welcome on 4bangers. But at highway driving or off-throttle, it quiets down and isn't intrusive. Definitely get this if you are concerned with pissing off your neighbours, you can seemingly get the best of both worlds with this exhaust

Fast and sounds great

Shipment was quick. As for the exhaust sound, i love it. It was like stock but louder however not annoying. No droning, deep tone.

Arrived on time, great quality,

Arrived on time, great quality, fit and finish. Used it to replace a tsudo performance I'd had on for almost a year and the interior drone finally did me in, so it had to go, there really is no drone with this system, you can just hear the exhaust inside under acceleration but it's still quiet and once your at highway speeds it's all but gone, I can actually hear the tires on the road again. All in all i would tell anyone who has a Fist to purchase this over any other system out there, thank you FSWERKS for an amazing product

Fswerks catback exhaust

Went to purchase the mishimoto catback and was informed it would be on backorder for 6 months. I opted for that system because it was resonated and offered black tips. Bought fswerks instead. Non resonated but with no drone sounds fantastic. Fit and finish fantastic and had the tips powder coated black. Still saved money and couldn't ask for more. Thanks fswerks

Fsworks st exhaust review

The St performs and sounds great. Quality not quite up to snuff but Acceptable. I had the exhaust installed pro. The fit is good Karl

Just what I was looking for

I replaced a 3" MBRP with this FSWERKS exhaust because the MBRP had a horrible drone and it felt like my car actually lost the punch it had with the stock exhaust. The FSWERKS exhaust fit better, sounds excellent, and my low end torque is back! .

FSWerks FiST cat back exhaust.

I love everything about this exhaust. Perfect fit, easy to install, and nice clamps. Materials and craftsmanship look great. Sound levels are right where i want them. Not too loud but nice deep tone. There's even a little bit of burble and pop now and then. I wasn't expecting much for gains but the car does run better than ever. Highly recommended!

Great exhaust for the price

FSWERKS got the shipment out right away and I had it less than a week from placing the order. I emailed the company with an installation question and got a fast and very complete response - very impressed. On the whole the exhaust is a quality piece and appears to be very well made. I was a bit skeptical of the slip fit joints but I think they actually have advantages over the flanged joints I'm used to - the slip fit allows some very precise adjustment and they are such a snug fit that the chance of leaks is essentially nil. The only reason I didn't give 5 stars here is because one of the muffler pipes was distorted (from welding to the muffler) and oval in shape and would not slip inside the connecting pipe - not even close. I spent about twice as much time correcting that issue than the rest of the installation. I ended up making a wooden buck to fit into my bench vice to squeeze the pipe back into a round shape - a lot of care is needed to avoid damaging the pipe and creating a source of leaks. What's disappointing is that an earlier reviewer had made the same comment and the issue was supposed to have been fixed - I can see that QC still needs to be improved. That minor complaint aside this is a good product. The butt dyno suggests a slight power increase and the sound is much improved over stock. It's a much deeper, more powerful, higher quality sound. When cruising on the highway it's good and quiet, with no drone, which is important for me.
