Please advise how to cut off a 6mm thick redundant bracket on an exhaust

[oldcardriver]

The bracket is about 6mm thick x 75 x 35mm, see pic, and needs to be significantly reduced in size or cut off, and I was thinking of using my 4” Wolf Grinderette and wondering which type of disc would be best, so that I wouldn’t need to apply too much pressure on the plate, so as not to damage the new exhaust? I was thinking that I will hold the plate in a vice.

I think that my car was one of the first off the production line after a model change, and I assume that the bracket was used on the earlier version but not on my later version. The exhaust on my car looks like the factory actually cut through the welds, but I don’t fancy doing that for fear of damaging the exhaust.

Standard 115mm grinder with a thin cutting disc will do it, I'd cut round the weld and leave it in place if it's not in the way, if you attempt to grind it flush you may risk making a hole in the exhaust

A metal cutting blade from Screwfix etc will eat that.

Are you sure it's 4" and not 4 1/2"?

Thanks, yes I’ve still got the box it came in, it’s a Wolf 4708 and it says 4” / 100mm, could be 30 or 40 years old!

Thanks, yes it’s 16mm and I appear to have the 2 small plates to lock it onto the grinder.

Could have done that with a hacksaw in the time it took to ask how to do it
