CAT to middle pipe fitting



atl

  Clio Trophy
Seems like every toy i buy has the exhaust botched...
Mine is currently blowing from where the cat meets the middle pipe. It has a rather rusty bracket holding them together and was blowing from the top part.

Surely this isnt meant to just press up against eachother to make an airtight seal?! Do i need exhaust paste or is there a better way?
Cant stand farting about with exhausts :mad:

High temp silicone is usually used to seal part or sleeving the joint by cutting off that olive joint and welding a small . pipe onto it

Looks like this is the thing to do then!

I thought you had one of those gauze flange bits in between! 😊

I'd seriously recommend spending a little bit of money on this getting the rubbish olive join removed once and for all.

The usual specialists and most exhaust places will be able to cut that off completely and weld a sleeve on. Have a search as many have had this done (including me).

Like this with a clamp on it:

I will do, i need a new middle section for my KTR system (that also doesnt sit right at the rear!! Right tailpipe is in the bumper and the left sticks out?!)
The whole thing has been cut a little bit short i believe. But i need to sort the blowing to drive it until i get that sorted.

You can get high temp stuff from Screwfix or Toolstation, it's rated to 300 deg max and 250deg continuous so pretty good.
It's what people use to seal stove pipes and such.
 
Much cheaper than halfords stuff I'm guessing? Il take a look in screw fix...interesting about the bathroom stuff, held up ok with the heat I take it then? Just don't want to be re-doing it again and again, read all the stories about paste crumbling away after no time at all and having to reapply, hoping to avoid that with the silicone :smile:

Does anyone know the size of the clamp needed for this cat to middle pipe flange? Am I right in think it's 50mm?
