  2. Mk2 Engine, Exhaust and Induction
    Hi all, I hope everyone is well. A bit of story first. I have since owning the ST installed a decat, MIL cheater and an eBay aftermarket o2 sensor. It has been off and on the car too many times to remember due to deciding whether I like it as the car was a daily. Sometimes for months and...

    Other than a sports cat are there options when it comes to decatting? Obviously all will void insurance etc but are there any that wont bring up an EM light on the dash? Also rough pricing people have found, fitted? Thanks

  8. Mk2 Engine, Exhaust and Induction
    I want to ask if somebody did this - put a 3" downpipe and decat(or sports cat) on a standart catback. I now have a 3" full custom made exhaust, with just one milltek 3" resonator(not the ultimate one, but smaller). It's kind of loud and it's not a problem now because it's not my daily driver...

    Cobra VENOM turbo back mini review. As there seems to be a lack of information regarding the system other than 'It's loud' and mostly just opinions from people who haven't run one I thought I'd post up a review of my own on how they are to live with. Let's get down to business, this is the...

    Hello folkes, Just a quick one for some of you out there. How does a decat+deres compare to a full decat Section 59 or Kms set up. Had mine done the other day as I was itching to get something on to give it some volume and I'm blown away with how loud it is. Just wondered the difference in...

    Good day all! My ST is currently decatted and I'm looking into getting it Deressed. Now I've seen a few videos of them both done - but what I want to know is how much noisier is it without the centre section? It's hard to tell from videos how much louder it becomes going from just a decat to...

    Hi! I've recently just fitted a Full Mongoose system to my Facelift ST. Firstly I have to say I was worried about Drone but there is hardly any at all and mine is fully De-res. Sounds absolutely quality when you put your foot down however, the fit, by my eyes is extremely poor. I know it is...
