Hi Folks

Working on my 1988 1000f-j today, I took my rear wheel out as I'm fitting new bearings and noticed that my right silencer is badly corroded round the joint with the downpipes, (a few pinholes), so I will probably need to replace my silencers in the next few months.

My question is, am I right in assuming the downpipes are stainless and although they are dirty should not be corroded? I'm looking at the cheapest option of fixing it so it may be just a pair of cans that I need rather than replacing the whole exhaust.

Thanks in advance for any advice.

Cheers, Steve

 

Sounds like the collector box pipe attachment collars ! ? you are talking about

I'd pull the cans off then go at it from inside the collector box and go at the pin
hole area's, and then outside around where the collars meet the collector box
WinPlus extreme epoxy putty is a good candidate for use & available on your side
of the pond.

Use a small light bbq grill wire brush knock off all the exterior rust

Just one thing tho' - if the collar(s) look too rusted & weak and there's a chance of
snapping one of due to excessive rust while removing the exhaust silencer, then I'd
just lightly brush clean and apply liberally from the outside only . Hate to see the
collar snap off removing the exhaust can - that can happen fairly easily if it's badly rusted.

 

Thanks for that, I'll get a couple of pics on later, your description sounds spot on. I imagine if the collar comes away from the silencer it could reduce the downpipes to scrap.

Photos to follow.

Cheers, Steve

 

Hi Sprock

I see what you mean now, the ends of the collector look ok, I'm guessing that is stainless, however, the right silencer above the collar is holed, the left looks ok. I reckon with the wheel out it should be easy enough to pack the holes with compound and use an exhaust wrap ro seal it for the time being.

Thanks for your help.

Cheers, Steve

 

Yeah, that will buff out just fine.

 

Haha, it's only a scratch

Cheers, Steve

 

Better put in a smiley face Teeks or we might just think that you were serious and going to apply some of that Britten/Munro type NZ ingenuity to the offending exhaust!

If it twer me - I'd be getting a new one.

We await the invention of clever welding rods that can adhere to rusty air.

I think maybe Woof will be interested in them for the Fiat resto.

Smiley face inserted as per directions, don't know that it actually adds to the overall tenor of the comment, but what the hell?, I'll take your advice on most things.

Cheers.

 

Hi Folks

Temporary/permanent repair done depending how long it lasts. Not got £250 for a pair of new cans, so it was a tenner spent in Halfords for two repair kits, Gun Gum Flexiwrap, (sticky foil) and a Gun Gum Bandage, cleaned up the surfaces as best as I could and it seems to have worked. Looks like someone had been there before me with the repair kits.

Cheers, Steve

 

Job done - good work Steve.
