Review and How To: Fitting a Supersprint Manifold to a Magnex Cat Bypass

  1. #1
    Hello ,

    As most of you might know if you read my progress thread i fitted a Supersprint manifold and Magnex cat bypass the other evening. It was only because i was doing a test fitting (off the car) whilst working on a How To Guide for fitting it, that i noticed a small problem with the mounting bracket on the down pipe (the part that joins to the cat) Fig: 4.

    The manifold itself came with a set of very large 17mm bolts, 4 washers (two different sizes), some very chunky springs and no instructions telling me why they were there. I decided to use the fitting kit Fig: 1 that i got from Citroen presuming that it would be a straight fit, when i noticed it just wouldnt work. I tried it every way you could think and then decided to have a play with the 17mm bolts and some of the special Citroen washers you see in Fig: 1 to get the best fit i could. As soon as i tried the new combination i realised that the nuts on the down pipe mounting bracket Fig: 4 were off centre meaning that the bolts were slightly misaligned when they passed through the large holes on the cat bypass mounting bracket Fig: 4A. Because of this very slight error i couldnt use the Citroen parts shown crossed out in Fig: 1.
    It was up to me to find the best possible solution and i couldnt use half the parts i had. In the end and after about an hour of messing about test fitting everything i hit upon the solution you see below. The pictures should explain everything because they have captions attatched to them but here is a quick run down.

    ( Fig: 1 + Fig: 2 + Gasket )

    There was no way i could use the parts marked with red crosses (Fig: 1), they just wouldnt fit with the 17mm bolts (Fig: 2) due to the misalignment and the Citroen bolts were too short (Fig: 1). The Supersprint springs were shite and would rattle their tits off on the 17mm bolts because they were too round IMO. So i decided to go with the Citroen springs because they were more of a snug fit and gave me plenty of thread to play with on the bolts. The only other parts i had were the washers from the supersprint set and in all honesty they came in handy (Fig: 2). As you gathered by now (Fig: 2) shows us the selection of parts we need for the job. The final peice of the jigsaw is the wire gasket that makes the seal between the two pipes. I was going to use the Citroen gasket but i wasnt happy with the fit and decided to use the more substantial gasket that Magnex supplied (Fig: 5).

    A simple picture showing how everything fits together after following the steps above.

    Two more pictures showing how everything looks when it has been fitted together. As you gathered allready this was the only way that i could get things to work. I didnt bother adjusting the bolts properly because it had to be undone again anyway.

    While we are on the subject of fitting exhausts i thought i would show you the bracket that fits the cat bypass to the centre section. It was a pain in the arse getting hold of this and the one supplied by Citroen was big enough to fit a Scania. In the end the lads at Mr Tyre (cheers Ste for reccomending them) came to the rescue and supplied me with the right one (no charge) . So to save you the pain here is the type of bracket you should need (see pics).

    Ok while i am on here is a quick review of the Supersprint manifold. If any of you are considering buying one then have a look here. Its only a quickie but should give you some idea of what you are getting. Please see the above guide for its quirks.

    The Supersprint manifold is a really impressive peice of kit (Pic: Supersprint Manifold). The build quality is spot on and the material used appears to be a very high quality. When you get the manifold out of the box you will notice it comes in two peices, dont panic like i did it should be the right one but just check anyway :d. If your like me then the first thing that will catch your eye are the nuts fitted to the three threads that are designed to hold the heat shield (Fig: 1 Manifold Review). The nuts on two of the threads nearest the back will be substantially damaged but i gather they are there to protect the thread when the manifold is being machined. You can take these off and dispose of them, if you do wish to fit a heat shield then you can replace the nuts with new ones.

    You will notice there are two plugs screwed into the side (Fig: Oxy Sensor). These are blocking the holes for the oxygen sensors because the Manifold fits several different cars there are two options. All you have to do is use the one that suits the car you have (1.1, 1.4, 1.6). All you need to do is unscrew the plug you will be using making sure the other is tight so it doesnt blow.

    The rear part of the down pipe is seperate (Fig: Two Parts A + Fig: Two Parts B) and the pipes just slide over the other pipes. There are splits in the end of the pipe so they fit easilly and the allen key bolts when tightened hold everything in place. I would recomend that you dont tighten them before you get it on the car. It makes the fitting a whole lot easier if you can seperate the two parts !!

    All in all i was really pleased with the manifold and its build quality. The only snag was fitting it to the cat bypass which was dissapointing. I would have thought that seeing as it is supposed to join up to a manufacturers cat then you would be able to use a Citroen fitting kit.

    Cheers for reading this, i hope that this helps. I will post a few more pictures showing how to fit it to the car in the near future.

    lmao tbh if someone is having a go at fitting an exhaust and they cant do that, they dont belong near a car

    (fast and the furious banter)

    good effort for the how to like lol lots of detail

    Did you actually read it ? because i dont think you did.

    It might look a simple job but it could save someone a whole lot of trouble because there is a specific problem with the fitment of the two parts. I suggest you have another look and then imagine getting everything on the car and finding out that the two parts wont fit properly lol.

    Good effort there lol… now go put a VTS engine in your car and make a guide on how to do that in as much detail…

    Cheers for the feedback. I will have to have a go at that one next weekend :d.
