  1. Mk3 Petrol Engine, Exhaust and Induction
    Had an MOT done on my 2016 Focus ST and the emissions test failed due to high Lambda readings. Since then, the garage has done multiple tests with very similar results. Checked the exhaust (no cracks/ holes), done a code readout (nothing) and about to take it for a boom up the motorway with...
  2. Mk2 Engine, Exhaust and Induction
    Hi all, I have milltek system from the turbo back and wanted a little more noise without being obnoxious, so opted for a cutout allowing me to choose between quiet and loud. Excellent! Well, it was for the first 10 miles or so until the plastic gearing in the valve motor got chewed up, now the...

  4. Mk4 Exhaust "How-to" Guides
    I recently installed the Mountune downpipe and GPF and absolutely love it. I decided to do it myself for several reasons, mainly the cost of installation and gaining experience. The process took about 4-5 hours as I didn't really know what I was doing, and was figuring it out as I went along...
  5. Focus ST Mk4 Non Technical Discussion
    Hi there, does anyone have photos of the stock undercarriage of the MK4 showing the exhaust, GPF, downpipe, etc...? I can only find images online of custom exhausts, and even then not the whole undercarriage.
  6. Mk3 Petrol Engine, Exhaust and Induction
    Hi everyone. I've made a video (with no talking or background music!) comparing the stock Ford exhaust to both the fully-resonated and semi-resonated Milltek Sport catback exhaust systems. There are hardly any decent videos showing what these expensive exhaust systems actually sound like, so I...
  7. Mk3 Petrol Engine, Exhaust and Induction
    Hi guys so I have had a custom exhaust fitted with Tony Banks (Leeds) very reputable company. Its a 2.5" cat back. I told them I wanted as little drone as possible but when I've got it the drone is so loud I have to shout tk passengers to have a conversation. And the bass noise it produces goes...

    Hi all, I'm looking for a resonated cat back system for my mk2 ST. I like the look of the milltek 2.75 system, but I'm not going to turn down other offers. I'm just putting the feelers out in case theres a good price on a second hand before biting the bullet. Thanks, Michael

    Hi everyone! Had my MK3 ST about 3 months now. Looking into a few bits for it. What do people think of the milltek exhausts on them? Not sure on whether to get the resonated, semi res or not res. Thanks!!!
  11. Mk2 ECU Remapping, Software & Tuning Packages
    Hello, I just ordered a 200 cell high flow cat 2.5" and I'm wondering if a remap is 100% required after installing it? At the moment I have ramair induction, airtec intercooler, scorpion non res catback (cat and downpipe is stock). Had a custom remap after these mods What would happen if I...
  12. Mk3 Petrol Engine, Exhaust and Induction
    I'm looking at a stage 2 remap soon, with sports cat to boot. I would like to go for cat back as well, however I'm a big fan of the standard hexagonal back box on the 3.5. However, looking around the market, I'm not seeing many cat back systems that can meet this requirement. They all seem to...
  13. Mk2 Engine, Exhaust and Induction
    Hello there, First of all, apologies if some of these questiosn have already been answered, but I couldn't find exact information I'm looking for 1. If I have a stock downpipe and cat, but I have a 2.5" Scorpion cat back, will any high flow cat/decat fit my exaust? Both 3"/2.5"? What I mean is...
  14. Mk2 Miscellaneous
    Hi there. I had my ST remapped recently (custom stage1 ~255hp). And now I'm planning to put a RamAir filter + Scorpion non-res cat back exhaust. Would these two upgrades increase any performance considering the car will have a better airflow? Or is it necessary to remap the car again to see any...
  15. Mk2 Engine, Exhaust and Induction
    Hello, Has anyone had experience with no brand cat back exhausts that are sold on ebay for relatively cheap prices? Something like this: https://www.ebay.com/itm/3-STAINLESS-CAT-BACK-EXHAUST-SYSTEM-FOR-FORD-FOCUS-MK2-2-5-ST-225-ST225-05-11/153593135707?hash=item23c2dd425b:g:xUUAAOSw~zde2m36...
  16. Mk2 Engine, Exhaust and Induction
    Hi there, I'm thinking about upgrading the exhaust of my focus mk2, but I couldn't really find information regarding the length of the exhaust. Considering there are two options, the 2 door and 4 door, the wheelbase should be longer, thus the length of the exhaust right?? Or do all exhausts fit...
  17. Mk2 Engine, Exhaust and Induction
    Had my car 6 months now and love it, however, it has a Milltek Sport deres on it and (you can probably guess the next bit) it's way too quiet. I've been looking at the Section 59 as a replacement, although the KMS Thunderstorm and Milltek ultimate are in the running. I have gone through varies...
  18. Car Care and Detailing
    Hi, Trying to get the best info. My 2017 ST exhaust is black. I tried the usual wash method. Apparently wheel cleaner is a good idea? Anyone tried this before?
  19. Mk3 Petrol Engine, Exhaust and Induction
    Any advice on a resonator delete? would you recommend? I am listening to sounds on you tube and am liking the tone difference. I am not really to worried about it needing to be louder but i like the different tone. I am however reading reviews that there may be a drone on motorways at around...
