Prius has a pinhole in the exhaust, apparently, at the bend where it starts going under the car. Seems likely to be caused by the misfiring filling the exhaust with petrol fumes I suppose, since they are meant to be very durable.

It’s so small I can’t really hear it, but not is due so I thought I’d maybe try a repair, maybe some of the bandage you can get. Reasonable for a bodge for a pinhole? Can they last a while?

Id just get a quick weld done. Bandage will work though

I bandaged the Galaxy for nearly a year – it was fine.

The recommended product if it’s near a bend seems to be Gun Gum flexiwrap, which looks like a strip of thin metal. Anyone used it? Can’t imagine how it would work..?

Exhaust putty and an aluminium can jubilee clipped in place. Basically the same as the Gun Gum flexiwrap. Used this after the old Mondeo’s exhaust split near the backbox. Forgot all about it until the MOT tester commented on Coca Cola making exhaust repair kits. The bodge was on for nearly a year before I replaced the exhaust.

GunGum splatttered in and soaked wet wrap bandage (hole right on a kink/join)
Belt n braces.

Bought the Gun Gum flexiwrap kit for £6. Given it’s such a small section this should armour it well enough to last a good while.
