When Fitting New Exhaust, or Sections
Hi All,
Don't know if this tip has been aired before, but here goes:
When fitting a complete or part exhaust system, I always smear silicon mastic/sealer, (any brand will do the trick) onto all the joints...
Then if in the future it's required to remove, it all comes apart very easily, no rusted or seized connections...
Cheers

Presumably this has to be a particular type of silicone sealant to deal with the high temperatures and, if so, where do you normally ge it from?
Thanks,

Hi Richard,
As far as I am aware, silicon will tollerate very high temperatures, not sure of the limit, but it cerainly works on car exhausts.
Silicon tubing is also used for the exhausts on model diesel engine exhausts, that's why I tried it...
Any silicon sealer will do, cheapest you can find, my last purchase was from Wickes, two for the price of one, but I suspect that offer has finished.
Cheers

Don't use a silicone based mastic as it gives off moisture as it cures, which gets trapped in the join by the mastic, which then plays corrosion havoc.
The best thing to do with exhausts is to get the local tyre and exhaust shed to fit it - most do free fitting (so there's no point tring to save cash doing it yerself) on systems and you can still stand there and watch them to ensure it's done properly.

If anyone does allow kwik-fit to fit an exhaust for them, I would definitely stand and watch them. I once saw a pillock beating the floorpan out of the way with a clubhammer because the exhaust didn't fit properly. Owner knew nothing about it until I told him. I get the feeling he did an awful lot of damage to that car.

I had an exhaust fitted to my mother's car which didn't fit, but the guy that did it got out the oxy-propane torch heated it up and bent the exhaust to the shape it should have been made rather than fixing the car.
Customising your car to fit the exhaust seems a bit excessive, what happens if the next exhaust is a different shape too? [;)]

silicone
Just seen the thread and thought I'd add my 3 penn'eth. On a Harley Sportster I had; all the exhaust sections were put together with silicone. At the time I mentioned it to the dealer thinking it was maybe a temp thing 'til the bike was 'run in' and he said that they (Harley Davidson) had been using it for years and never had a problem with it. Obviously it didn't have a 'cat' though.
