I have an original Ferrari exhaust on my GT4 and although fairly old it doesn't look to be in too bad a shape. I have however noticed that under one of the exit pipes a small hole has appeared, about the size of a thumb nail. I have prodded round it and made it about as big as it will go.
Deciding that this small hole doesn't warrent a new system, I went round a number of auto shops looking for something to repair the hole with and came back with a handfull of products. The most suitable seemed to be some self adheasive metal tape, which I applied over the cleaned and prepared area. The result looked pretty good and off I went for the afternoon. Upon return - having done about 90 miles - I checked that my splendid repair was still holding, but there was nothing there apart from a few marks where the tape had been! I then read the packet it came in (which maybe I should have done in the shop) and it said that the tape was only suitable for temperatures upto 172C (341F). This seems quite low and I assume that the pipe gets hotter than this (esp when driven hard).
Anyway, sorry for the ramblings, my question is - what is the best way to repair this type of hole, the products I have are 'repair putty' and 'repair bandage'. I think the bandage is out of the equation as you need to be able to wrap the bandage completely round the pipe in question, which I cannot as the bracket joining it to the other pipe prevents this. Sooo, I guess I am left with the putty, has anyone had any success with this stuff??
