Gents, refitting my Y-piece due to some leakage that was causing backfire. Was going to apply some copper grease, but though I'd ask first what everyone else uses? Cheers

Put the cat back and it won;t back fire
y piece and std can you can get some awesome bangs :-D
Shouldn;t be as bad with a remus and db killer tho


Hi Temperature silicon![]()
Was looking at that today in halfords, but instructions said 'not advised for exhaust systems'. Tim, do you have a certain brand you recommend?

Go to your local Exhaust fitter and see what they use.
When the instructions say 'Not Advised...ask yourself, why not?![]()
Its because silicone is supposed to kill the Cat, as you have removed yours it wont affect you. Dont worry about special expensive silicone use a cheap £1 builder's clear silicone in a mastic gun. works wonders.
Cheers ....
I'm getting my rear end re-packed next week so when I push it back in I'll use silicone to stop the leaks ......![]()

Doesn't silicone kill the O2 sensor? That said, for all I know you leave the O2 sensor screwed into the cat when you fit a Y-piece so same difference on a GS?
