where the exhaust mounts to the engine i have 2 rusted rounded bolts and i need to remove them to install a new pipe ?? anyone got the best possible way to remove the without spending alot ??
depends what clearance you have, things I do; first of all, a decent socket, grips on the flats, the cheaper ones grip the corners, if rounded, sometimes a wall drive socket will shift it, a under size socket tapped on, maybe not a size down metric but a A/F or whitworth socket mini stilsons/mini mole grips, I use a dremel with a diamond cutting wheel, cut a slot, then with a chisel and hammer tap it round, until it can be undone with screwdriver. Guess you could get a slot with bit of hack saw blade. what ever you choose a bit of penetrating oil left for a while, then a bit of heat helps matters.
your lucky you have bolts, someone previously bodged a ikea allen key in the exhaust, took me nearly a whole day of banging and tapping it round to get it out
