    I have normally gone and done custom exhausts on my previous cars, but this time I was looking into having a bolt on specifically engineered for the FiST. So I can easily put in on or take it off.
    So far I have come across this




    No figures or sound clips up yet, but I just wanted to share. I'm not pulling the trigger on anything yet.

    Sorry if I double posted...the desktop site wasn't working so I tried again through tapatalk.

    While I'm glad to see exhaust options being developed, I'm a little disappointed they are only 2.25". Give us 2.5" at least!

    Would there be a reason to use 2.25? Or is that just sticking with the stock diameter? A larger pipe would increase flow but do we have to worry about things like back pressure?

    They probably had a standard Fiesta exhaust they adapted to the ST.

    I'm sure the baby snail creates plenty of back pressure. I'd save your money for a high flow cat/downpipe and skip the catback till dynos are done. Its a lot of money for some pipe that may not be needed till the stuff up front is cleaned up.

    I like the sound of the factory exhaust but it is pretty quiet. Some people are looking for sound.

    I personally want performance first but if I don't get good sound I'll be tweaking things (I'll be making a 3" system from mandrel bends if no one CNC bends a nice 3" cat back and I'll be working cat forward too, EFR turbo probably).

    from what I have gathered, a properly designed exhaust for the ST will do wonders for the car. The ST exhaust is the same in the US as it is in Europe, where it needs to be quiet and restrictive.

    I don't think I like it... Sounds a little "wet" to me. I want a subtle note that isn't too loud but you can still hear it growl. Like the the sound you hear in the cabin from the symposer... but coming out the back.

    Love the sound of the MRT exhaust. Milltek also has some nice one's out (youtube them)

    I would love an exhaust that sounds stock until you get on it and performance oriented. I hate raspy exhaust systems.

    You could always splice in an electric cutout...

    Haha I have to admit I had no idea what that was (probably a good thing) googled it and here is what I found haha I think I'll pass

    Quiet For The Street, Riot For The Strip!!
    Go from stealth quiet to wide open power and experience the gains even if you are already enjoying an aftermarket exhaust system. You control the volume, you control the power. Open your exhaust with the flip of a switch. Run it closed, run it all the way open or any position in between. Adjust your back pressure to save gas.

    Does not matter whether you call it a electric exhaust cutout, exhaust dump or e-cutout you know your getting the ultimate exhaust upgrade for your car or truck.

    I want to see what fswerks comes up with. If you check out their site for the focus st they have a race exhaust and a stealth exhaust.

    The stealth exhaust is made with magnafow mufflers and has the sound I'm looking for.

    I know it won't sound the same but I'm Hoping it's something similar for the fiesta st

    Thanks for posting that video! That's exactly what I am looking for to

    I am really tempted to try the Burns 3" race muffler and a full 3" exhaust.

    With the turbo to quiet it a little, the race muffler might keep it quiet enough and light weight.

    I'm going to have to read up on resonator tech because I think they shape the sound and can help with drone.

    yeah, I love it! The car sounds very mean and aggressive. The tips aren't oversized or stupid looking. I would say MRT nailed the exhaust design.
