Hi All, I recently fitted a pair of termignoni slip ons to my panigale. Whilst doing the install i had to remove all the piping from the engine and split all the pipes and refit. When doing this i cleaned up the pipe sections and reassembled without any sealant between each join. With everything fitted i now have a very strong smell of fuel constantly and in two areas i noticed leaks from the pipe joins. To note there are no cracks or anything and i did attempt to then push everything back in tightly (Springs on pipes are attached). This has now settle after i temporary sealed the joints with Gun Gum as a test before i readdress the install but i wanted to know when refitting all these pipes do you use a specific sealant on the joins? On every system i have installed i have never added anything more just ensured everything is fitted nice and snug but im wondering having removed and cleaned all the pipes maybe i have removed the sealant previously applied.
I’ve got a termi system and the joins have always leaked a bit of soot. I’m going to try some of this next time i have it apart. https://www.ebay.co.uk/itm/Wurth-Si...ature-Special-250-UK-KART-STORE-/331518792034
I was going to order some loctite exhaust sealant on amazon and literally apply liberally on all the pipe joins and then use a mallet to knock them all in correctly. Im hoping this will cure the issue and have everything sealed up tightly. Good to know others have wondered the same thing. From the factory is any kind of sealant used on these pipings?
Hard to say as the termi’s aren’t factory fit. The fit/ tolerance’s will be different to the ducati standard systems ( don’t know who manufactures them for ducati).
I once used Gun Gum on my 916 link pipe, sealed perfectly but was a pig to separate the next time I removed it. Don't use anything now and any leaks seem to seal once everything's hot.
I was reading about Austin racing exhausts, some of which are made from Inconel, http://www.austinracing.com/content/4-about-us
I asked the same question after refitting my 1199 exhaust and the joints were blowing what is the best recommendations ??
For those bikes with Catalytic converters (or possibly DPF for the one Diesel bike I've ever seen) make sure you don't use ANY* sealant prior (upstream) to the CAT. I've only used graphite powder (or just a soft pencil) to help slip things together.... *Manufacturers instructions supersede this.
I removed my earlier post as to not confuse others, my bikes do not have sensors so silicone works perfectly well. Steve
Agree, I was always told “don’t - you won’t get it appart in the future”. However, I respect @final_edition ’s knowledge but would like to know how easy they are to take apart again.

Steve, do you use that on ALL the joints? How easy/difficult is it to disassemble the exhaust system at a future date? Also, is any gas leak without it anything other than negligible? TIA
The copper sealer I use doesn't set hard, like a cement type sealer, Gun Gum etc. It remains flexible and the exhaust comes apart easily. I haven't used it with Co2 sensors, as I remove them.
i haven't read the whole thread. maybe its been said. i've seen standard Black or clear RTV silicon used on exhausts. it seams to work well, tho i dont use it. cleans off nice, comes apart nice to.
