    was overtaking 4 cars and heard a huge gutteral groan on way back from viewing a house

    feck! says the wife...

    pulled over and saw that the cat pipe that mates to the fixing studs to the turbo has popped off, looks like weld failed or when the car was having a new exhaust fitted the other day the garage have twisted the cat when mating up to it and weakened the weld somehow

    letting the car cool now and will refit it tomorrow to see how it runs

    should be able to get it rewelded do you think? or is it new cat time?

    wife uses the car for commuting so a decat is not going to help her mpg's

    if its good enough to weld that'll be cheaper than a cat mate, i'd try that first.

    £250 for a MAF? WOW !!

    It's a common failure mate, a reweld will be fine.

    Ahh yes the early ones, bugger. Weld that DP and she will be good to go, it's the old, cast welded to steel problem.

    try and find someone who use TiG welding, the penetration even with dissimilar metals is excellent. I've welded stainless to mild with almost no visible seam and no cracking at the HAZ area at all using TiG.

    sorry mate, I sympathise with your plight having no access to pit or ramp either, its a total bastard. Its a shame the diy garage thing never took off, I thought i had nothing better to do than look up the nearest one.....unfortunately they seem to have followed the betamax and the Atari.....to "good idea heaven" lol

    Are there no mobile mechs or welders near your area?

    I'd pay £25 for someone else to lay in the rain getting my cat off ha ha :)
