Sealing the Exhaust

[Craigfa]

Have managed to get the exhaust fitted, but hit the expected problem of not getting it to seal properly at any of the join sections (all four of the joints arounf the link sections. Any top tips? Is there any sealant type stuff you can use when putting it together....or high temp sealant for applying around the joints after fitting?

You need to use an exhaust jointing paste I found GunGum was the best as it is a bit more fluid than some other makes. But you need to apply it and assemble within 2 or 3 minutes and any movement after 5 or so minutes is likely to reduce the likelihood of a good seal. I had to disassemble and re-assemble mine 3 times before I got a seal last time, but mine is a custom exhaust and is more complex than the standard setup (more joints and at funny and by awkward angles)

I agree and if I remember correctly you need to run the engine/exhaust system up to temp soon after fitting to get it to seal/set.I also found the clamps around the exhaust at the manifold joint tended to distort the diameter a bit (ie crush it)try and get these distortions to line up again if they are evident, the outer pipe will tend to bend back in again easier at this point.
Hope that makes sense.
