    Hi dane. Sorry missed your reply yesterday. They fitted Ok just had to file 2 of the holes in the flanges a bit more.

    Performance wise it's just felt a little smoother and revved a little bit harder at the top end. I'll post up some dyno figures as soon as i fix my leaking radiator. (replace i mean)

    Same as you. Used new studs and nuts, and the manifold to cat join just used some longer nuts and bolts.

    No need to apologise Steve, your info is very helpful & appreciated. is it a difficult job? I am mechanically minded but dont want to mess something up as its my only form of transport for myself & the wife.

    Are the longer bolts & nuts a must then I take it?

    Yeah, they are a must as the new header dont come threaded. You can pick them up from a decent hardware shop..
    It not too difficult and removing the washer bottle gives you a lot more room, but TBH It will be a pain on the floor without a ramp as some of the lower manifold studs are a pig to get to. One tip is if you do want to go ahead and fit them wire brush and WD40 all the studs and nuts a few days before you start the job......

    Happy days & thank you again. This could be a new mod for me to get done too. Have you heat wrapped your manifold?

    Sorry for all the questions

    Thank you Steve, help is always appreciated. My reason for heat wrapping is only due to things ive heard about the increased temperature in the engine bay due to the stainless steel getting hotter. This may or may not effect cold air intake even though I have a good heat shield and heat foil on the engine bay side of that too.

    I never noticed any loss of performance with the extra heat, my filter is enclosed....

    I have had the same stainless steel headers as Steve fitted on my car for a few months now, they do make the acceleration smoother and the exhaust note very pleasing. I heat sprayed and wrapped mine in the end too

    This leads me to my next question.

    Is it worth me heat wrapping the rest of my exhaust system and has anyone done it please?

    Thank you.
