    Busy day fixing exhaust etc.

    Got back home finally yesterday after a couple of weeks away to find my exhaust sounding like its blowing, again! and a rubbing noise coming on decelleration which is typical. Then my brake light has been playing up on and off too.

    So ive spent most of today working on my car trying to fix all of these problems and fitting my samco's.

    I found the problem, or one of which was the exhaust rubbing. Got it up on the jack and axle stands to find that the exhaust is rubbing against the rear driveshaft, i think you dont notice it once your on throttle because the exhaust is louder then and where it has moved a bit it is catching on the bottom of the car too, so i reckon this is probably the cause of it blowing.

    Anyhow i got hold of prism this morning who had the car in a couple of weeks ago to fix the blowing. They were quite understanding about it and wanted me to bring it down on friday, which would mean another day off work so taking it in on sat and they are opening specially to do it. Ive already taken 3 or 4days off work getting this exhaust fitted etc so far so its just as well and its a bit of a trek taking it there all the while too.

    At least it will be fixed and its getting sorted pretty quickly, but it is a very tight fit for the exhaust with it being 3" all the way thru. Im gonna ask them about the possiblity of making the induction kit dahlback style too and see how much they would want to do it, there is a few companies in sandy that do SS too so they may be worth approaching too

    Ive got most of the samco's in now, and decided while that bits off....

    You know the story, ive ended up taking no end of bits and pieces off while im at it and decided to give the ISV a clean up and the rocker cover a little polish and replace my cracked coil pack cover. I was gonna get it chromed but decided to do the crackle finish on it so the coils can dissipate the heat better. Goto wait a few more hours to do the last coat on that before i can refit it though

    Also while i was fitting the samco's i found a boost leak i didnt know i had, didnt think it seemed to be going as well as it was, anyway it was the pipe onto the throttle body so hopefully i will be back to full flavour behaviour with the samco's fitted.

    Lets see if i can get it all back together before i go out thsi eve

      Looks like the bend in the pipe is not quite right for the position of the drive shaft..
      I think the pipe on my ur is doing something similar, do you get a kind of hollow droning sound inside the car at certain rpms? Engine vibes in the pedals?

        Haven't been getting vibration in pedal but been getting a bit of a droning noise inside. it could be that your exhaust is touching on the body somewhere i guess?

        the noise i mostly get is metallic rubbing sound when you're off the throttle.

          Greg, where did you get the exhaust made from and how much did it cost?

          Is it 3 inch from the turbo back?

            Right well I've just been underneath and its not touching anywhere... It must be just because its really loud. It looks like there's a hole appearing in the box though Stainless too.

              hole in exhaust dont sound good, id get it fixed before it gets bigger if i were you.

              @sal.

              Exhaust is 3" turbo back, used marco's downpipe which was modified on exit slightly when they fitted new exhaust.

              exhaust was built by prism motorsport in enfield, got recommend to them by Mark H from when they did his WG pipe. All in the exhaust cost me £800 inc the downpipe, unfourtunately prism said they wouldn't do another one that cheap because they didnt realise how difficult it was to fit 3" onto a S2 coupe.

              Even still it would be a pretty competitive rate, its worth a trip down to look at all the other rare metal they have in there and the twin turbo V8 Bmw they have.

                Checked it out again today, deffo got a hole, leaking soot..

                Its a Scorpion so I get a new one, lifetime warranty

                Also they dont make the trumpet shaped tail pipes any more so I get slashcuts, which is cool and more stock looking, except they're bigger.

                  I much prefer the look of the slash cut tails. DTM doesnt suit the S2 i dont think.

                  I got my car all back together after fitting the samcos and doing the coil cover. I have another problem now, the throttle body hose had some nicks in it and leaking i think with the new samcos fitted im getting silly boost now, could be WGFV so if anyone wants to let me borrow one to test it out? mine an ABY btw.

                    I must admit i did like the crackle finish on mark H's car so decided to give it a try with my coil pack. I need to give it another coat i reckon and re polish the 20v turbo bit again. Did it a bit this morning but didnt have enough time to do it properly in the end.

                    plus my elbows needed some more grease! lol

                      I recognise that wastegate cap! I thought you would have polished that also?

                        LOL, I havent fitted the one you sent me yet corey. Im still trying to decided wether to polish it myself, send it away or have it powder coated or something.

                        I didnt want to change it just yet because it will need adjusting again and I want to sort this boost problem out before anything else. Did you want me to send you the other one i take off back to you?

                            Got my exhaust fixed yesterday, didnt take them long to do it. Just need the downpipe bracket adjusting. I think this is in part due to the powerflex snub mount not fitting as well as it should.

                            If someone can take some photos of the standard snub mount fitted on their car, in particular the way it lines up with the bracket i will try to get powerflex to modify the design to suit.

                            But my adage of getting one thing fixed and another goes seems to be true this week, my spa design gauge is playing up now. Only half of the display is illuminating now.

                            Seems to be the time of year for things to go wrong on my car!

                              Im still having ongoing problems with my car with overboosting, i got a new WGFV thru from martyn yesterday and fitted it but the car still goes way into overboost so ive disconnected the wgfv again now to try something else.

                              any ideas what be causing it to over boost so much? I fixed the boost leak I didnt know i had in the throttle body hose when i fitted the samco's. WG boost seems ok but can differe by 0.2 bar depending on the gear etc.

                              I was wondering if it could be the DV but that only release when you lift off the throttle/ change gear etc.

                              any ideas? i want to get it fixed before billing.
