Exhaust sealant - recommended type?

[Barson]

I removed my cat over the weekend - bolts were easy peasy with a little heat.


I'm ready to install the bypass, but wonder what sealant compund i should use on the gasket end (and also the muffler clip end?) - I've never messed with exhausts before :oops:



cheer me dears!

you can get an exhaust putty from Halfrauds, et all - cant remember the name, but it comes in a red tube with either silver or white writing from memory.

You wont need much though - in fact, I dont think I've got any on my car, it was "just" a case of put the bypass pipe on, put the U clamp on and the gasket (mine matched up to a Daewoo when I took my bypass pipe into Partco!), put the bolts and nuts on, get the toolbox out and be prepared to swear alot getting the bugger to line up

Have fun! :wink:

from memory, there were certain by-pass pipes that needed the lip ground off, just to let you know cheers tt

If your talking about the end with the square flange on ? Didnt you get a purpose made gasket with it ? You can buy gasket material to make your own up or go with the putty as kindly suggested above

thanks for the replies.

I got a gasket with it, I just wanted to know whether I need to compliment the paper gasket with a sealant.


I already had a go at lining up the bypass...didn't seem to want to fit. :wink: :?

In that case you only need the gasket on the flange end, the other end just clamps on 'snugly'. test fit this end first to make sure it doesnt need 'braying' in.

If the flanged end doesnt fit properly you will have to, as suggested above, cut the lip off.

Where did you get your bypass pipe from bud?

Ordinary silicone sealer works bang on. I know its probably not the first thing you would think of, me neither, but all the companies who manufacture the bike exhaust I supply, use it when they put them together.
I've used it loads of times on various stuff since & it works a treat. (You would thinkit would melt, but it does'nt)

will the semi hardening red hamerite do? same stuff i use on my rocker gaskets?
