Advice needed: exhaust sealing material

[Guest Stephen S]

My new Ixil silencer fits over the main exhaust, but there is a problem.

 

The stock silencer has a graphite seal between it and the exhaust, about 3mm thick and 30mm wide.

 

I can chip this off with no difficulty.

 

I think I need a replacement "interface" between slip-on silencer and exhaust to prevent them welding themselves together. They are a tight push fit.

 

What material (paste, seal, etc) would you recommend for this purpose?

 

Thanks all, and Happy Easter to you all.

I know little about the pros & cons of different materials but, when I fitted an aftermarket (British-made, can't remember the make) silencer to my Guzzi, the manufacturer's recommendation was a straightforward domestic (heat-resistant) silicone sealant.

 

Of course, me being me, I completely ignored them (I'd bought some exhaust-fitting cement whilst waiting for the courier & wasn't worried about swapping silencers at M.O.T. time as the new one was road-legal). The thought of using silicone sealant does however, in hindsight, make a sort of sense to me.

 

Sure others will be along with more detailed & more helpful answers after they've finished their eggs.

It seems wrong, but regular silicone sealant works. It shouldn't, but it does.

Can you still get "Gun Gum"? I used to use that as an exhaust gasket on every car I ever owned in the 80's and 90's.......

Steve have a look on Halfords site --don't buy from there they are too expensive --but just for info--as Keith say Gun Gum is what we use on cars or did use--there will be some new products that will do the same job.
