Exhaust assembly cream

[jordan1]

I need some exhaust assemby cream/paste for my bike new exhaust, leaking in a few places. It seems like tight fits but blows when running. I have seen Ed China use some on Wheeler Dealers which would be ideal, it appears very smooth and creamy, unlike some thick pasted I have used in the past. Anyone any idea what make it was?.
TIA

I use high temp flue silicone and steer clear of the pastes that go hard. I have used normal clear bath silicone sealant before on bikes, the nice thing about it is you can get them apart again and it seems to keep the corrosion at bay too.

Yes, I need it for where the pipes push on to the short head tubes.

my megane had a similar issue, liberal amounts of rtv did it for me

Only ever used the holts branded exhaust gear before. Cant say if it goes hard the exhaust only lasted a year before i had to scrap it.

It's called Firegum.
We used to use tons of the stuff.

I used liberal
Amounts of firegum on the megane and every time it would blow again after going for a drive...the rtv is still holding nicely and the exhaust is t blowing in that joint any more...it's blowing of the manifold now but I don't care about that

Firegum, hate the stuff, not used it for years. Best results I had with it were to get a good fit on the parts preferably removing any seams in the pipes and once fitted warm the joint to dry the paste as the water & acids combined with back pressure in the system blow and wash the paste out of any gaps. I'm sure being water based it's designed to start corrosion and form a proper seal you can never disassemble!

I just use a decent clear silicone, but bear in mind normal silicone will rot a steel exhaust

Gungum was the holts version?

Gun gum was/is repair paste not assembly.
Firegum works perfectly well if you know how to fit exhausts properly.

Please share.......

I'm just saying that I spent 8 years as an exhaust fitter and we never used anything other than Firegum for assembly.
If you fit the clamps properly then joints rarely cause a problem.

Ah - never heard of firegum before only gungum.

You need assembly paste rather than repair paste. They are very different. Assembly paste does not set hard and it is no problem taking joints apart.

What is the name of the paste you are using? Firegum goes rock hard.

No More Nails works for me.

I will have a look at it when I am in the workshop again, possibly later
