Bought an exhaust for my RX7 recently, its used but most of it is in not too bad shape, however the pre silencer is probably the worst bit The main issue I have is that theres a stud snapped off in it  The other studs aren't looking particularly amazing but might clean up ok Essentially I'm looking for someone near to Coventry that would be able to get this out and put a new stud in for me I'd take it to a garage but I have a feeling it would either get lost/thrown on the scrap pile or I'd get charged a silly amount to sort it Any suggestions anyone? |

Sorry I am too far away from you - I'm guessing you're not after ways to do it yourself because it isn't a hard job if you've got the right tools - I'll bet there's someone on here who can do it for you easily enough. If not a local machine shop would tackle that very quickly - probably a better bet than a garage.

Clean up the studs as much as possible then heat the surrounding flange until glowing red at base of studs
Clamp studs tight with mole grips. It'll turn out or through. Try both directions. Once it starts to move, get some lube around the edge of the hole to help it along.
I use this method regularly to refurb m/c exhausts and it rarely fails
Failing that it's either drill it out and retap or spark erode

If it can be fixed with a hammer, then it must be an electrical fault

cheers taurus Yeah I don't really have the tools to heat it up at the moment and have a go at sorting it myself so was hoping there'd be someone nearby who could do it or recommend a machine shop as you say. It can be tricky to find the little machine shops is the issue! Wilk Cheers for that, if I had access to something to heat it up enough I'd have a go myself but don't really have anything to do it with unfortunately |

As said, heat is your fried in these cases, MAP is better than propane, then again OXY is better than MAP but MAP is the easyest to get in small amounts from BQ ect  |

Just a tip if you can't grip the stud right enough with the grips....
Turn the flange upside down and grip the stud in a large vice, apply heat then rotate the part around the stud!

Rather than trying to grip the stud I find it's better to put a nut over it and weld it to the stud, then use an appropriate socket to try and undo it. Less chance of it slipping and the heat from welding may help free it off a little too

I'd linish it flat, centre ounch and drill then tap.
