    Decatted but needs MOT

    Decat

    Hi everyone, Only me again, with the simple questions. Will I need to change my manifold on my 172 in order to decat? I mean, I have a decat pipe and recently ordered a stealth system, but have no idea whether everything will match up Cheers, Carlos.

    172 Cup cold start issue.

    So I picked up a 172 cup to be used as a track / weekend fun car. It runs great except right after a cold start it takes a couple of minutes before it's driveable as it stutters a lot when it's cold. It does have a decatted exhaust which I think may be part of the issue, is there any way to...

    To Decat Or Not... Clio 200

    So I've got a bit of a dilemma at the moment, over whether I should decat the Clio or not. I have had a decat manifold fitted so that with the Akrapovic means the cars fairly loud, and I'm not sure how much louder I would like it to be really, but the car makes a fair amount of pops and bangs...

    172 Manifold

    Looking at getting a de-cat system set up on my 172 Clio, how do I tell there difference between a 172 and a 182 manifold? Seems difficult to track down a decent priced 172 de-cat pipe but loads of 182 de-cats on ebay etc? So I'm hoping mines has a 182 manifold on it already.

    Designed/ made my own Decat

    Hi Guys, I started looking for a decat a while ago, mostly as i wanted a little more noise from my 182. I found that most of the decats on the market seem to be a constant diameter with a large step at one end or the other. My reckoning is that this is going to disturb the flow though the...
